The alloy used in the die casting is mainly nonferrous alloy, and the black metal (steel, iron, etc.) is less used because of the mold material and so on. In the nonferrous alloy die casting, the aluminum alloy is widely used, and the zinc alloy is the second one. The following is a brief introduction to the situation of the die-casting of non-ferrous metals.
(1) classification, die casting of nonferrous alloys blocked contraction composite shrinkage free shrinkage of lead alloy -----0.2-0.3% 0.3-0.4% 0.4-0.5% alloy with low melting point alloy of tin zinc alloy --------0.3-0.4% 0.4-0.6% 0.6-0.8% --0.3-0.5% 0.5-0.7% 0.7-0.9% Al Si casting nonferrous alloy Aluminum Alloy Al Cu Al Mg ---0.5-0.7% 0.7-0.9% 0.9-1.1% high melting point alloy Al Zn Mg alloy ----------0.5-0.7% 0.7-0.9% 0.9-1.1% copper alloy
(2), all kinds of die casting alloy recommended casting temperature alloy type casting wall thickness less than 3mm casting average wall thickness >3mm is simple in structure and complex structure of simple structure with complex structure
