Copper-nickel Strips
Copper-nickel alloy is made of copper, iron, nickel, zinc and trace elements, through processing by ingots, hot rolled, cold rolled, heat treatment, surface cleaning, cutting, finishing, packing and other processes. the product has a beautiful gloss, excellent hot and cold workability, ductility, corrosion resistance, fatigue resistance, high flexibility, good electrical and mechanical properties and shielding performance. It is widely used in the manufacture of wet and corrosive media in the work of structural components, flexible components, precision instruments, communications industry, liquid crystal oscillation element housings, medical equipment, construction, wind instruments and utensils, and daily necessities and so on.
