Very high strength & elasticity. _Hardness & friction resistance. _Corrosion resistance.

Our CuNiSn alloys are work hardened, hardened by spinodal decomposition, and – in some cases – cold worked. Their state of the art metallurgical treatments and conditions provide them with excellent mechanical elasticity and hardness properties. Copper Nickel Tin based products can compete with the mechanical performance of Beryllium Coppers and offer excellent surface properties: very good resistance to corrosion, shock, friction, and depolishing.

  • Beryllium free
  • Titanium free
  • Lead free 
  • Recyclability

CuNiSn alloys can replace copper-beryllium alloys, superalloys, and copper-titanium alloys.
