The whole process of the application of aluminum castings in production is to deal with many other castings with unparalleled advantages. Its advantages are from the perspective of the lightweight automobile manufacturing industry. Common applications are especially for cars. The key is that the relative density of aluminum castings is lower than that of iron and steel castings, and the compressive strength is very high. After a series of competitions, aluminum castings excel, which relieves a part of it. Therefore, in the well-known aviation and machinery manufacturing industries, aluminum alloy profiles have a very large weight. Because of its low melting point, aluminum castings also have particularly important functions in the whole process of operation. Aluminum casting is widely used in metal material type and working pressure casting, and it has become the basic original method. In that way, the essential quality of the casting is improved, the surface is smooth and the precision is higher, and the output power of the production is also improved a lot.
Aluminum castings have an excellent casting effect in the whole process of operation. The key is that the melting point of its products is low, so it can be widely used in metal material type and its working pressure casting and other casting methods, so that it will develop The meaning of casting quality, limit precision and surface smoothness level and its production output power.
The solidification and vaporization heat of aluminum castings is relatively large. Under the same weight standard, the solidification time of lithium bromide solution is much longer than that of pig iron and steel castings. It has good liquidity and is very beneficial in casting thick-walled and chaotic castings.
After aluminum castings are burned into the mold with high-temperature metal material, there will be a lot of vapor in the aluminum casting processing plant. This must be smoothly drained from the mold. This type of characteristic that allows vapor to pass is called It is air permeability, otherwise there will be insufficient air vents inside, which will endanger the quality. Its air permeability and moisture clay composition have a certain connection.
