Supply of Zinc White Copper C75200 High Strength Corrosion-Resistant Plate, Bar, C75200 White Copper Strip, Factory Direct Sales

Material Name: C75200 Zinc White Copper Bar

Grade: C75200

Standard: GB/T 4423-1992

C75200 Zinc White Copper Bar Characteristics and Application Range:

It is a structural copper-nickel alloy with a beautiful silvery-white appearance, commonly known as German silver (originally Chinese silver). This alloy has high strength and corrosion resistance, good plasticity, and can withstand pressure processing well in both hot and cold states. It has poor machinability and weldability, and its elasticity is superior to QSn6.5-0.1.
