What is aluminum casting? It is understood that castings obtained by forging aluminum or aluminum alloys are called aluminum castings. The actual development is to introduce liquid aluminum or aluminum alloy into the core of the metal material mold or sand mold to obtain aluminum or aluminum alloy parts. In addition, the appearance and specifications of the aluminum castings and steel molds may be different. In application, the application of aluminum castings is very common, in which automobile and industrial production parts account for the majority.
1. The key advantages of aluminum castings
Aluminum castings, not only from the application of raw materials, but also from other aspects, all have some advantages that other castings do not have. The key is:
(1) The appearance design is beautiful and generous, and the quality is light, so that the transportation can be carried out easily. And in the car, this is also a big benefit.
(2) The relative density of aluminum alloy is significantly lower than that of pig iron, steel castings, etc., but it is much higher in compressive strength and corrosion resistance. Therefore, under the same net load, the application of aluminum castings can greatly reduce the net weight of the structure.
(3) For the surface of raw materials such as aluminum alloy, the surface smoothness is very good, and the forging performance is also very good.
