Alloy 500

Our product, containing 63% nickel, is a nickel-copper-based alloy with additions of titanium and aluminium. This material achieves considerably high strength after age hardening, benefiting from excellent mechanical property retention across temperatures ranging from 480°C to sub-zero. Low magnetic permeability is another attribute that makes the alloy highly suitable for electronics. With high fatigue strength, Alloy 500 is easy to fabricate and weld, although heavy machining is best achieved while the material is hot-worked and quenched or annealed.

Corrosion Resistance

The corrosion resistance of the alloy compares similarly to Alloy 400. It offers excellent protection in various industrial media, including chemical and marine environments, hydrochloric and sulphuric acids, alkalis, and non-oxidising mineral salts. The material also corrodes at a low rate in high-velocity seawater. Alloy 500 resists stress corrosion cracking (SCC) which gives it suitability for sour gas environments, although the alloy is susceptible if fully age-hardened.

Product Suitability

Alloy 500 should be considered for applications requiring excellent corrosion resistance, strength and hardness, which performs well across various temperatures. Market beneficiaries include sub-sea and above-sea service, oil, gas, petrochemical and marine applications.
