Copper Nickel Alloy

Ultibron Copper Nickel Alloy

ULTIBRON by Smiths Metal Centres Ltd - our brand of extra high strength copper nickel alloy which also offers outstanding corrosion resistance.

For Extreme Environments

This high-performance alloy boasts a mechanical strength exceeding that of nickel aluminium bronze and this is achieved in the 'as supplied' condition to the benefit of the user. The overall property combination makes the material highly suitable for use in a diverse range of extreme environments, particularly in the marine, offshore oil and gas and aerospace markets.

  • Oil & gas, marine and naval applications
