Product Application Areas :
General Engineering Furniture, Architectural Grill Work.

Characteristics :
A Copper and Zinc Alloy containing small amount of Arsenic which is added as an inhibitor against dezincification. The alloy exhibits a good combination of strength and ductility and is commonly selected whenever excellant cold working properties and relatively low cost are desirable. Service environment must be considered to predict corrosion behaviour. Alloy is often used for a variety of deep drawn components.
