Finishing Options

Alloy K500 Nickel Bar

Excellent corrosion resistance.


We stock Alloy K500 bars in the cold drawn and hot worked condition and in various sizes.

Alloy K500 aged-hardened nickel-copper bars offer increased hardness and strength with excellent corrosion resistance.


Alloy K500 (NA18) is an age-hardened nickel-copper alloy with excellent corrosion resistance. The product benefits from increased hardness and strength but is more susceptible to stress corrosion cracking (SCC) due to being age-hardened. With exceptionally high dimensional stability, the material is highly suitable for cryogenic applications.


Further Benefits

Alloy K500 (NA18) displays excellent corrosion resistance in fast-flowing and stagnant or slow-moving saltwater and finds extensive use in offshore and marine applications. Alloy K500 retains its mechanical properties at sub-zero and elevated temperatures. The material is very similar in performance characteristics to Alloy 400 but with greater strength and hardness.
