  • Detailed Description
  • Monel K500 – Nickel-Copper Alloy

    Monel K500 is a Nickel-Copper alloy that is precipitation hardenable, due to the additions of Aluminium and Titanium. It combines the corrosion resistance of Monel 400 but gives the added advantage of extra strength and hardness (as a result of its age hardening ability).
