Used for casting various aluminum alloy parts. According to the different alloy composition and performance requirements, can be divided into aluminum-silicon, aluminum-copper, aluminum-magnesium, aluminum-zinc casting aluminum alloy ingots. For example, the common ZL102 belongs to aluminum-silicon casting aluminum alloy ingot. It has good casting performance, corrosion resistance and wear resistance. It is commonly used for casting automobile parts, such as engine blocks, cylinder heads and pistons, as well as various mechanical parts.
