UNS C70600

UNS C70600 is a 90% copper and 10% nickel alloy with tiny traces of other elements such as iron and manganese. Copper increases the material's overall strength, and the trace elements improve corrosion resistance. The result is an engineering alloy that offers outstanding corrosion resistance, particularly in marine/saltwater environments.

Machinability & Weldability

UNS C70600 provides good strength and creep resistance while being easy to machine and weld with good cold and hot forming capabilities. The alloy is highly suitable for applications in the marine sector, including forged components. It represents an ideal alternative for operating environments where chloride stress corrosion cracking is problematic, as stainless steel is unsuitable.

Biofouling Performance

The alloy's typical resistance to biofouling and marine corrosion is excellent. Biofouling is a common issue in above-sea and subsea scenarios, where contaminants such as algae, micro-organisms, and even small animals can impair a component or structure's performance. The alloy's biofouling resistance also reduces the risk of pitting, although the material is susceptible to pitting in contaminated water containing hydrogen sulphide.
