The copper-nickel alloy with extremely low nickel content is also called nickel free cupronickel. It comes with excellent elasticity, corrosion resistance and much lower nickel content than the international standard. The low nickel copper alloy is ideal for manufacturing glasses accessories, zippers, fasteners, decorations and other metal components. Powerway copper-nickel alloy has been listed among the new national key products and has been ranked first in the market for eight continuous years.
