Zinc alloy used for casting and die casting contains alloying additions of aluminum, copper, magnesium, silicon, titanium, and boron

摘要

Zinc alloy contains (in wt. %): 0.01-6 aluminum, 0.01-1.5 copper, 0.001-0.06 magnesium, 0.001-0.2 silicon, 0.002-0.05 titanium, and 0.0002-0.005 boron, and a balance of zinc. An Independent claim is also included for a process for the production of the zinc alloy in the form of pigs, sheets, strips or wires, comprising reacting a fine zinc alloy containing (in wt.%) 0.1-4.2 aluminum, 0.03-1.5 copper, 0.001-0.06 magnesium and 0.002-0.04 silicon with an aluminum-titanium-boron pre-alloy and optionally a silicon and/or chromium alloy and then processing to pigs, sheets, strips or wires. Preferred Features: The zinc alloy contains additionally contains up to 0.2 wt.% chromium. The alloy preferably contains 0.004-0.07 titanium, and 0.0002-0.005 boron.
