BZn18-26 Zinc White Copper Composition Standard GB/T 4423-1992

Supply of highly malleable BZn18-26 zinc-nickel copper rods and plates, high-strength copper-nickel alloy, factory direct sales

Grade: BZn18-26 zinc-nickel copper

Standard: GB/T 4423-1992

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...
