Formula: Cu 62/Ni 18/Zn 20
Form: Tube
Material: Copper/Nickel/Zinc (Nickel Silver)
Commodity: Alloys
Nickel Silver Alloy Tube (Cu62/Ni18/Zn20) combines the mechanical strength of copper, the corrosion resistance of nickel, and the workability of zinc in a precise 62-18-20 composition. This alloy exhibits excellent cold-forming capability, high wear resistance, and a stable, tarnish-resistant surface finish, making it suitable for both functional and decorative purposes. It finds extensive use in marine hardware, precision engineering components, musical instrument manufacturing, and decorative architectural fittings. Specific applications include corrosion-resistant tubing in fluid handling systems, load-bearing structural elements in mechanical assemblies, and high-quality fittings where aesthetics and durability are equally important. In research and product development, this composition is prized for its balanced properties, supporting innovations in hybrid structural-functional designs. Its combination of performance, machinability, and appearance ensures value in both industrial and artisanal applications.
