Corrosion resistance

CuZn36 has a good resistance to water, water vapor, various salt solutions, many organic liquids. However, a corrosion in the form of "dezincification" occurs under certain conditions (water with high Cl content and low carbonate hardness). Further, this material has a tendency in the cold worked condition at the outer and / or inner tensile stress with simultaneous action of certain pleas (ammonia, amines, ammonium salts) to "stress corrosion cracking". Tensile stresses can also be subsequently introduced by incorporation or further processing. Heat treatment can prevent stress corrosion cracking. Even composite products can be obtained in the relaxed state. Components can become stress relief annealed or soft annealed.
