Shanghai Metal Corporation is one of the main suppliers of  Nickel silver strips/Copper nichel zinc strips/Nic in Shanghai. we can supply all the prime quality Nickel silver strips/Copper nichel zinc strips/Nic to meet your request. With strong emphasis on quality and customer satisfaction, Shanghai Metal Corporation has become one of the most reliable sources of quality Nickel silver strips/Copper nichel zinc strips/Nic products  in the international market.

With a beautiful color with, scalability, anti-fatigue and corrosion resistance are excellent, full of deep-drawing performance.

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.
