Product classification
Alloy 400 is a nickel-copper alloy known for its excellent corrosion resistance, particularly in marine environments. It is often used in applications such as pumps, valves, and marine hardware due to its ability to withstand harsh conditions.
Alloy 400 generally has superior corrosion resistance compared to nickel-copper. It is more resistant to corrosion in reducing media than pure nickel, and more resistant to corrosion in oxidizing media than pure copper. Its corrosion resistance to sulfuric acid, phosphoric acid, and carbon is very good. In particular, it has excellent resistance to hydrochloric acid corrosion and also shows good corrosion resistance to hot concentrated alkalis. Alloy 400 exhibits outstanding corrosion resistance in fluorine gas, hydrochloric acid, sulfuric acid, hydrofluoric acid, and their derivatives. Additionally, it is more corrosion-resistant in seawater than copper-based alloys.
