PRODUCT DESCRIPTION

2.4375 is a nickel-copper alloy which combines the excellentcorrosion resistance of MONEL alloy 400 with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanium to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3(Ti, Al) are precipitated throughout the matrix. The thermal processing used to effect precipitation is commonly called age hardening oraging.

We supply high-quality Monel K-500 in various forms, including:
  • Round Bars, Hex Bars, Flat Bars
  • Sheets, Plates, Strips
  • Wires, Tubes, Forgings
  • Custom Machined Components
