Brass vs Bronze vs Pure Copper vs Copper Alloys: An in-depth look at their differences

The comparison of brass to bronze to copper and its copper alloys is crucial as these metals can be easily confused. In addition, the distinction between these materials is also very subtle. As a result, development engineers or designers can be seriously confused when it comes to material selection. In particular, the similarity of these metal constituent elements makes it more difficult to classify and select them.

Although they differ in color, they are not noticeable, and you may not be able to quickly identify which models of these metals are. What's harder is that you can't use any of them for all apps. Although they have many similarities, such as the same proportion of copper-containing elements. However, the proportions of other metal elements are different, which results in different copper alloys with many unique properties. Therefore, the choice of copper in different application scenarios is not the same and needs to be taken seriously.

This article provides you with a detailed comparison that will go from material type differences in different countries to establishing the differences between brass, bronze, copper, and copper alloys. It also outlines their unique properties, available alloys, applications, and more. The information here will help you choose the best metal for your metal project.

1. Comparison table of copper and copper alloy national grades

The reason why copper models in different countries are different is because different countries and regions have their systems and practices in standardization and naming. As an important metal material, copper is widely used in various applications in different countries and regions, such as industrial manufacturing, construction, electronics, and other fields. To ensure the quality, performance, and suitability of materials, each country and region has developed its standards and specifications, including the nomenclature and model system of copper.

Standards and norms in different countries and regions may be affected by factors such as history, technology, industrial demand, and domestic and foreign markets, so the naming and model of copper materials may vary internationally. This difference sometimes leads to difficulties in understanding cross-border exchanges and cooperation but it is better able to meet specific needs and requirements in the respective domestic markets.

The following is a comparison table of copper and copper alloy models in major countries in the world:

2. Brass vs Bronze vs Copper vs Copper Alloys: A Detailed Comparison

The above table describes the model standards of copper and copper alloys in major countries in the world, and engineers, technicians, and procurement personnel are invited to pay special attention to relevant data, which is an important basis for global supply chain management.

2.1 Commonly used copper alloys and a brief description

Commonly used copper alloys are divided into four categories: copper, brass, bronze and cupronickel. As a more common type of copper on the market, the following is the difference between these types of copper by richconn:

Copper: An alloy composed of one or several other elements added to a pure copper matrix. Pure copper is purple-red, also known as copper. Pure copper has a density of 8.96 and a melting point of 1083 °C, which has excellent electrical conductivity, thermal conductivity, ductility, and corrosion resistance. It is mainly used to make electrical equipment such as generators, busbars, cables, switching devices, transformers, heat exchangers, pipelines, flat collectors, and other heat-conduction equipment for solar heating devices.

Brass: A copper alloy with zinc as the main added element, with an aesthetic yellow color, collectively known as brass. Copper-zinc binary alloys are called ordinary brass or simple brass. Brass above the ternary is called special brass or complex brass. Brass alloys containing less than 36% zinc are composed of solid solutions and have good cold working properties, such as brass containing 30% zinc is commonly used to make cartridge cases, commonly known as bullet case brass or seven-three brass. Brass alloys containing zinc between 36~42% are composed of solid solutions, of which the most commonly used is 64 brass containing 40% zinc. To improve the performance of ordinary brass, other elements such as aluminum, nickel, tin, silicon, lead, etc. are often added. Aluminum can improve the strength, hardness, and corrosion resistance of brass, but reduce plasticity, suitable for sea wheel condenser pipes and other corrosion-resistant parts. Tin can improve the strength of brass and corrosion resistance to seawater, so it is called naval brass, which is used as ship thermal equipment and propellers. Lead can improve the cutting performance of brass; This free-cutting brass is often used as a watch part. Brass castings are commonly used to make valves and pipe fittings.

Bronze: originally refers to copper-tin alloys, and copper alloys other than brass and white copper are called bronze, and often preceded by the name of bronze with the name of the first main added element. Tin bronze has good casting performance, friction reduction, and mechanical properties, and is suitable for the manufacture of bearings, worm gears, gears, etc. Lead bronze is a bearing material widely used in modern engines and grinding machines. Aluminum bronze has high strength, good wear resistance, and corrosion resistance, and is used to cast high-load gears, bushings, marine screws, etc. Bronze plating and phosphor bronze have high elastic limits and good electrical conductivity, suitable for the manufacture of precision springs and electrical contact elements, bronze plating is also used to manufacture non-sparking tools used in coal mines and oil depots.

Cupronickel: A copper alloy with nickel as the main added element. Copper-nickel binary alloy is called ordinary copper; Copper alloys with iron, zinc, aluminum, and other elements are called complex cupronickel. Industrial cupronickel is divided into two categories: structural cupronickel and electrical cupronickel. Structural cupronickel is characterized by good mechanical properties corrosion resistance, and beautiful color. This cupronickel is widely used in the manufacture of precision machinery, chemical machinery, and ship components. Electrical cupronickel generally has good thermoelectric properties. Manganese copper, constantan, and copper are suitable copper with different content and are materials used in the manufacture of precision electrical instruments, rheostats, precision resistors, strain gauges, thermocouples, etc.

2.2 Brass, bronze and copper material properties

Understanding the properties and differences of copper materials will help you make better choices between brass, bronze, or copper alloys. Only if you have a deeper understanding of its different characteristics and differences, you are a qualified developer, designer, engineer, or senior procurement, the following provides you with some details we summarize, which will always help you in some aspects.

Different element composition: the essence of material properties

Trace elements into copper are inevitable, due to the different characteristics of the elements, they cannot be solid soluble in copper, trace solid solution many solid solutions, infinite miscibility, solid solubility with the temperature decline and drastic decrease, solid phase transition under the solid phase, so the impact on copper properties is very different.

Pure copper is a non-ferrous metal that exists in a pure state. Unlike bronze and brass, this naturally occurring metal can be processed directly.

Brass, on the other hand, is an alloy of copper and zinc. It usually contains lead and may also contain manganese, iron, aluminum, silicon, and other elements.

Bronze is an alloy of copper and usually contains large amounts of tin as its main element. However, it also contains nickel, aluminum, phosphorus, zinc, etc.

More detailed "Influence of Elements on Copper and Copper Alloys"

1.Corrosion resistance

One way for manufacturers to distinguish bronze from copper is by corrosion resistance. Bronze, as an alloy of copper, usually oxidizes when exposed to air. As a result, it forms a protective layer (mottled passivation film). Therefore, bronze is well protected against corrosion.

Bronze can withstand saltwater environments. Therefore, it is very useful in marine applications and marine accessories. However, copper is reduced in constant exposure to chlorine compounds. Copper also forms a protective layer of oxidation and has excellent corrosion resistance.

Brass, on the other hand, is less resistant to corrosion than bronze and copper. However, some brass varieties that contain a lot of manganese are generally more resistant to corrosion. In summary, bronze is the most corrosion-resistant of the three metal options.


Bronze is a strong and durable material that does not bend easily. Its high corrosion resistance also makes it very durable. Copper is also a strong material. However, it is softer than bronze. You can stretch and bend it easily, but it will hardly crack or scratch. Therefore, it is a durable material. However, brass is prone to cracking and breakage. Its corrosion resistance is also poor.

Thermal conductivity

The thermal conductivity of pure copper does not change with increasing temperature, while the thermal conductivity of alloy copper increases with increasing temperature. Therefore, the thermal conductivity of red copper does not change, and the thermal conductivity of brass changes.


Red copper has excellent electrical conductivity and is used as a measure of electrical conductivity, that is, the conductivity of red copper is defined as 100%, which measures the conductivity of other metals. According to this standard, brass has a conductivity of 28%.


The hardness of a material refers to its ability to resist local deformation. In terms of hardness index, brass has a hardness of 3-4 and pure copper has a hardness of 2.5-3, so brass is harder, and the higher the zinc content, the harder the brass is.


The weight factor also plays a vital role in helping you choose between brass, bronze, or copper. According to their density, bronze, and brass are very close in weight. However, if you must choose bronze or brass for projects that require lightweight metal, brass is a better choice. This is because it is the lightest of the three metals. Its density is about 8720 kg per cubic meter.

Bronze, on the other hand, has a density of about 7400 to 8900 kg per cubic meter. Copper is the heaviest of the three metals, with a density of 8930 kilograms per cubic meter.


Compared to brass and bronze, copper has better workability. It is a more flexible metal that can be bent, rotated, and other machining. In addition, copper alloys are generally highly malleable. Bronze is a harder, stronger metal that is not prone to bending. Brass is also less flexible, which makes it less workable.


In their respective fields, brass, bronze, and copper are all weldable. These metals are joined using silicon bronze welding, MIG equipment, or other techniques. Oxygen-free copper is generally easier to weld. The same goes for copper oxide. MIG and TIG are the most popular techniques for welding this metal.

Brass alloys also support MIG, TIG, and silver welding. However, leaded alloys are more difficult to solder. Alloys with lower zinc content are easier to weld. Among bronze varieties, lead-free bronze is fair in weldability. However, they often crack under stress, and SMAW may be the best technique. But our common cast brass is not weldable.

8.Surface finish

In terms of surface finish, there are significant differences between brass, bronze, and copper. Because different materials require different surface treatment methods when facing specific needs. Making the right choice can guarantee how a material will perform in a specific environment.

For example, brass and bronze often require special oxidation treatment to form a protective oxide film. This film can prevent the external environment from attacking the metal surface. Copper, on the other hand, may require stricter corrosion protection measures to ensure a stable service life over a long period.

Therefore, when considering the use environment and requirements of materials, it is particularly important to choose the appropriate surface treatment method. Different metal materials require different care to ensure they are always in top condition


The price of copper is relatively low, averaging around 60 yuan per kilogram. The price of alloys varies depending on their composition, ranging from tens to thousands of dollars. In general, alloys containing rare metals (such as platinum, palladium, etc.) are more expensive, while alloys containing common metals (such as aluminum, magnesium, etc.) are less expensive.

There are many reasons why the price of alloys is higher than copper, such as higher technical costs and equipment investment costs for alloy production; more R&D and experimental costs are required for the ratio between different components; the cost of raw materials and transportation costs of some alloys is also higher.

2.3 Differences in material properties: an introduction to essential differences.

Differences in electrical conductivity of brass, bronze, and copper

The difference in electrical and thermal conductivity will help you choose the best material for your application.

1.Electrical conductivity

Copper is one of the materials used in the manufacturing industry to grade electrical materials. Manufacturers express the conductivity grade of these materials in terms of copper. Therefore, we can say that copper has a conductivity of 100%.

Brass, on the other hand, conductivity is about 28% that of copper, while bronze has about 15%. The lower rating of bronze may be due to its alloying element composition.

2.Thermal conductivity

Of the three metals, bronze has the highest thermal conductivity. Its thermal conductivity is between 229 and 1440 BTU/hr-ft2-°F. Copper followed by 223 BTU/hr-ft2-°F. Brass has the worst thermal conductivity of the three metals, with a thermal conductivity of 64 BTU/hr-ft2-°F.

The difference in the strength between brass, bronze, and copper

The strength of the material is critical to helping you decide on the most appropriate application. Therefore, you must consider this factor when comparing brass vs bronze vs copper.

3.Tensile Strength

When metal strength is critical to the application, bronze is often the ideal choice. This is because its tensile strength is between 350 and 635 MPa. Brass is second, with the highest tensile strength of 338 to 469 MPa. Copper, on the other hand, has a tensile strength of 210 MPa.

4.Yield strength

Compared to brass and copper, bronze has a higher yield strength. It has a yield strength of 125 - 800 MPa, while brass has a yield strength of about 95 to 124 MPa. Copper has the lowest yield strength at 33.3 MPa.

5.Molding capability

Your materials must meet quality requirements in terms of formability. Therefore, it is better to make the right choice.


Copper can withstand plastic deformation without damage. As a result, it has exceptional formability, and manufacturers can make micron-sized threads from this metal. Some bronze alloys are also very malleable. A good example is PB1 phosphor bronze, which achieves cold forming. On the other hand, brass is difficult to form due to its very low flexibility.

7.Melting point

The lower the melting point of the material, the better its formability. Copper's melting point of 1085°C may limit its formability. Bronze, on the other hand, has a melting point of 913°C, while brass has a melting point of 927°C.

8.Look and feel

Distinguishing between brass, bronze, and copper can be difficult because they have similarities in appearance. However, there are some subtle differences to be aware of.


It can be easy to distinguish bronze from brass by color. The brass has a dark gold color, similar to ordinary stone. This makes brass an ideal material for fittings. Bronze, on the other hand, has a slightly reddish-brown color. The color of bronze is very similar to the color of copper. But the reddish-brown color of bronze has a dull golden hue, while the reddish-brown color of newly exposed copper is very distinctive.


Copper has a score of 35 on the Brinell hardness scale, while brass scores between 55 and 73. Bronze, on the other hand, scores between 40 and 420. This result shows that bronze is the hardest of the three metals. In addition, it is more brittle and therefore more likely to break.
