ABSTRACT:
A low-alloy zinc material is disclosed containing a minor amount of titanium, e.g., 0.05 to 1.0 weight percent titanium. The alloy material can be formed into objects which have good cold workability, strength and resistance to corrosion. The zinc alloy materials are tarnish-resistant and can readily be embossed, hollowed, pressed, bent, or the like. They are especially useful as coining material to form coins, coin blanks, plaques, medals, and other useful and/or decorative objects.
