Alloy 400 – High Performance as Standard

Alloy 400 is a nickel-copper alloy that is used extensively in the energy sector, especially in off-shore operations. This is because it displays a strong resistance to seawater and doesn’t lose structural integrity in areas with strong currents. Also, it performs well in high temperatures and is often used in heat exchangers and boilers.

Due to its strength and resistance to corrosion, Alloy 400 performs well in a variety of different conditions. In fact, it represents an excellent choice, as it is relatively cheaper to produce than other metals while still offering first-rate resistance to most alkalis, salts, and a variety of atmospheric conditions.

Alloy 400 tubing and fittings are commonly used in the following industries:

  • Marine engineering
  • Petrochemical operations
  • Chemical plants
