What Are the Advantages of Cast Aluminum Parts

The continuous development of society, people's lives are increasingly high demand for aluminum casting process is also increasing in demand. In our use and use of aluminum casting process, do we understand the aluminum casting production out of aluminum die casting parts have what advantages?


Advantages are as follows.

1, good product quality: castings of high dimensional accuracy, generally equivalent to 6 ~ 7, up to level 4; surface finish is good, generally equivalent to 5-8: high strength and hardness, strength is generally higher than the sand casting 25-30%, but the elongation rate decreased by about 70%; dimensional stability, interchangeability is good; can die-casting aluminum thin-walled complex castings. For example, the current zinc alloy die casting aluminum parts minimum wall thickness of up to 0.3mm; aluminum alloy castings up to 0.5mm; minimum casting aperture diameter of 0.7mm; minimum pitch of 0.75mm.

2, high production efficiency machine productivity, such as J Ⅲ 3 horizontal cold air die casting aluminum machine average eight hours can die casting aluminum 600 ~ 700 times, small hot room die casting aluminum machine average every eight hours can die casting aluminum 3000 ~ 7000 times; die casting aluminum type life long, a pay die casting aluminum type, die casting aluminum bell alloy, life up to hundreds of thousands of times, or even millions of times; easy to


Mechanization and automation.

3, the economic effect is excellent because of the die-casting aluminum parts size is accurate, the table flood clean and other advantages. Generally no longer mechanical processing and direct use, or processing is very small, so both improve the utilization of metal, but also reduces a large number of processing equipment and man-hours, casting price is cheap; Can use a combination of die-casting aluminum to other metal or non-metallic materials. Both save assembly time and save metal.

4, aluminum castings in the use of the process of its advantages (interpretation: can overwhelm each other's favorable situation) is quite remarkable, the use of products in the field, the automotive industry occupies a large part, especially now the automotive industry pay special attention to the characteristics of the lightweight, because of the aluminum castings in the automotive industry in order to get a relatively wide range of applications, aluminum casting density than the density of its iron casting as well as steel casting requirements of light! The density of aluminum castings is actually lighter than the iron castings and steel castings, and the strength of aluminum castings in the use of the process is relatively large.

5, aluminum castings of their own weight is relatively light, but its products can withstand a relatively high weight, in the design process can effectively reduce the weight of the casting structure, so such equipment in industry, transportation machinery and power machinery to achieve a relatively wide range of use.

6, in the chemical industry, its aluminum (Al) castings to a certain extent is also more widely used, in the use of its aluminum alloy and pure aluminum in the thermal conductivity, will be made of aluminum castings can be used in chemical production after the heat exchange device (type: hybrid and surface type and power machinery to have good thermal conductivity of the parts. Non-ferrous metal casting in the use of non-ferrous metal materials accounted for a large share (sometimes nearly half), the formation of a large and complex casting alloy series. Non-ferrous casting non-ferrous alloy casting, in non-ferrous metal alloys, copper alloys, aluminum alloys, magnesium alloys, zinc alloys, etc. can be used for casting.

7, aluminum (Al) castings density than cast iron and cast steel is small, while the specific strength is higher. Non-ferrous metal casting non-ferrous metal smelters tend to a certain chemical composition of the metal ingot supply, for subsequent processes to formulate various types of alloys; smelters and processing plants are often set up separately. Therefore, in accepting the same load conditions, the use of aluminum alloy castings, can reduce the layout of the weight, so in the aviation industry and power machinery and transport machinery production, aluminum castings are widely used.

8, aluminum castings have outstanding casting function. Because of the low melting point, it can be widely used in metal type and pressure casting and other casting methods, in order to improve the casting of the connotation of quality, scale accuracy and appearance of the degree of smoothness and production power.

9, aluminum castings because of the latent heat of condensation, under the same conditions as the portion, the aluminum liquid condensation process time continuous than cast steel and cast iron much longer, put the mobility is outstanding, is conducive to casting of thin-walled and layout of the castings of the messy.
