The Common materials of Die casting

Alloy die castings used mainly non-ferrous alloys, as ferrous metals (steel, iron, etc.) As the mold material and other issues, less use. The colored aluminum alloy die castings again using more extensive, followed by zinc alloy. Following is a brief look at the situation of non-ferrous metal die-casting.
(1), classification die-casting non-ferrous alloys hindered shrink shrink shrink freely mixing lead alloy ----- 0.2-0.3% 0.3-0.4% 0.4-0.5% low-melting alloy solder alloy zinc alloy -------- 0.3 -0.4% 0.4-0.6% 0.6-0.8% 0.5-0.7% LAS --0.3-0.5% 0.7-0.9% copper aluminum-magnesium alloy die-colored aluminum alloy aluminum --- 0.5-0.7% 0.7-0.9% 0.9-1.1% refractory alloy aluminum and zinc based alloys ---------- 0.5-0.7% 0.7-0.9% 0.9-1.1% Cu alloy

Magnesium alloy 640-680 ℃ 660-700 ℃ 640-670 ℃ 650-690 ℃
Copper alloy ordinary brass 910-930 ℃ 940-980 ℃ 900-930 ℃ 900-950 ℃
Silicon brass 900-920 ℃ 930-970 ℃ 910-940 ℃ 910-940 ℃
* Note: ① generally casting temperature of molten metal holding furnace to a temperature measurement.

② zinc alloy casting temperature must not exceed 450 ℃, in order to avoid coarse grains.
