Description

The material ZnAl12Cu1, a fine zinc block metal alloy acc. to ASTM B 669, german marking ZA 12, is usually the first choice with the transition coming from steel, brass or aluminum. It possesses best casting bar during conventional sand casting assembly. The alloy does not exhibit best workability and has not hard places. It is outstanding pressure tight, even in thin cross sections and is on high polish sharpening and polishingable. The alloy is used mainly for sand and ingot casting, in addition, for pressure casting on cold chamber machines.
