Product
Application Areas :
Sugar
Industries, hand Pumps, Plumbing, Furniture, General
Engineering, Ammunitions.
Characteristics
:
A
Copper and Zinc Alloy containing Aluminum and small
amount of Arsenic. This is added as inhibitor against
dezincification. The alloy exhibits a good combination
of strength and ductility and is commonly selected
whenever excellent cold working properties and
relatively low cost are desirable. Severe environment
must be considered to predict corrosion behavior. The
alloy is often used for variety of deep drawn
components.
