MAIN CHARACTERISTICS 

CuZn36 is the major brass alloy for the cold forming process. Even though brasses with lower Zinc content have better cold forming properties, CuZn36 is the most used alloy. Reasons for this are on the one hand economical due to lower price of Zinc compared to Copper, on the other hand the forming properties of this alloy meet the demand of many applications.

Characterized by a good resistance to water, water vapour, different saline solutions, many organic liquids and, sea and industrial atmosphere. Not particularly resistant under certain conditions to water with high chlorine-content and low carbonate-hardness. A form of corrosion called “dezincification” can occur. A heat treatment can help to avoid stress corrosion cracking.
