NS30 is a wrought copper nickel silicon alloy CuNi7Si2Cr1 designed for applications requiring a combination of high thermal dissipation, high strength, resistance to shocks and that is also corrosion resistant.

It is easily machined into complex components whilst being environmentally friendly, being both lead and beryllium free. It is a direct replacement to CuBe2 C172000 that exhibits a superior combination of properties.

NS30 is used within the automotive, tooling and welding industries thanks to its outstanding physical and mechanical properties. 

  • Key applications include Plastic Injection & Molding, Injection and Blow Cores and Cavities, High Pressure Die Casting Tooling, Plunger Tips / Pistons, Moving Plates Bushings
  • NS30 is used in tooling, thanks to the combination of its thermal and mechanical strength, excelling in high-speed production cycles where high and rapid heat dissipation is needed, thus allowing high production rates supported by high quality finishing.

 Composition, standards, norms: CuNi7Si2Cr1.
