Standard Zinc Alloys

Among all standard zinc alloys, #2 zinc alloy possesses higher strength and hardness which last over a long period of time. Its good creep resistance (deformation under high temperature and stress) and anti-wear property make it an ideal material for products requiring durability and strong mechanical properties.

Applications

Industrial fittings and gravity casting of high-strength operations, such as automotive parts, gears, metal moulds, injection moulding tools
