Nickel silver strips/Copper nichel zinc strips/Nickel silver copper alloy
Contact now
Copper nickel increase significantly enhance the strength, corrosion resistance, hardness, resistance and pyroelectricity, and reduce the temperature coefficient of resistance. Therefore, other than the copper-nickel alloy of copper alloy mechanical properties, physical properties are simply too good, good ductility, hardness, color, appearance, corrosion resistance, full of deep-drawing performance, widely used in shipbuilding, petrochemical, electronics, instrumentation, medical devices, Daily necessities, handicrafts and other fields, and is an important resistance and thermocouple alloys.
Features:
Good color, high toughness, high strength, high stability, excellent elasticity with fine silver gloss, good fatigue, rust and corrosion resistance properties. C7521 and C7541 have very good deep-drawing performance.
Application:
Shielding material for communication electronics, antenna material, EMI-shielding material, spring contact, flexible terminal, environmentally-friendly plating-free electronic parts and components, quartz oscillator, high-level material and electric material.
