Alloy K-500 Nickel AlloyAlloy K-500

Precipitation Hardenable Nickel-Copper Alloy

Alloy K-500 is a precipitation/age hardenable nickel-copper alloy providing high mechanical strength combined with excellent corrosion resistance.

Tensile strength is typically twice and yield strength three times that of alloy 400 nickel-copper. The alloy exhibits outstanding properties at sub-zero (including cryogenic) temperatures at which ductility and toughness are virtually unimpaired. It also possesses low permeability and is non-magnetic to temperatures as low as minus 101°C.

Corrosion Resistance:

Alloy K-500 provides excellent resistance to corrosion in seawater, oil & gas environments and a wide variety of industrial media. The corrosion resistance of alloy K-500 is substantially equivalent to that of alloy 400 (non-hardenable nickel-copper alloy) except that, when in the age-hardened condition, alloy K-500 has a greater tendency toward stress corrosion cracking in some media.

Fabrication:

Heavy machining of alloy K-500 is best achieved when the material is in the annealed or hot-worked and quenched condition.

It is common practise to machine slightly oversize, age-harden, then finish to size. However, age hardened material can be finish machined to close tolerances and fine finishes. The alloy can be joined by industry-standard welding, brazing and soft soldering processes.
