Cupro NS (CuNi2SiCr) Hard Copper Alloy
Cupro NS (CuNi2SiCr)
Cupro NS® is a nickel and silicon-based alloy designed for use in high temperature and corrosive environments.
What is Cupro NS® (CuNi2SiCr) Material?
Cupro NS® is a copper alloy developed by Sağlam Metal. Cupro NS® is a nickel and silicon-based alloy designed for use in high temperature and corrosive environments. Cupro NS® material is widely used especially in power plants, chemical processing plants and petrochemical industries due to its resistance to high temperatures and resistance to corrosion. The durability of CuproNS® is ensured by the formation of a passivating oxide layer that does not corrode at high temperatures. This alloy is also ideal for high temperature resistant electrodes, heating elements and other high temperature applications.
