die casting the alloy is mainly nonferrous alloys, as black metal ( steel, iron ) as the mold materials, being less frequently used. And non-ferrous alloy die casting with aluminum alloy is used widely, the zinc alloy. To briefly introduce the situation of die casting non-ferrous metals.

( 1), die casting non-ferrous alloy classification hindered contraction of mixed shrinkage free shrinkage of lead alloy - the 0.2-0.3% 0.3-0.4% 0.4-0.5% of low melting point alloy tin alloy 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% aluminum silicon casting non-ferrous alloy aluminum alloy alcu aluminium-magnesium system - 0.5-0.7% 0.7-0.9% 0.9-1.1% high melting point alloy aluminum zinc magnesium alloy - 0.5-0.7% 0.7-0.9% 0.9-1.1% copper alloy

( 2 ), all types of die casting alloy casting alloy casting temperature recommended species average wall thickness less than 3mm casting average wall thickness > 3mm has the advantages of simple structure of complex structure has the advantages of simple structure of complex structure

* Note : the casting temperature to heat furnace temperature measurement of liquid metal.

The zinc alloy casting temperature can not be higher than 450 centigrade, in order to avoid coarse grain.
