Classification of copper nickel alloys

Copper nickel alloys are classified as manganese white copper, ferrous white copper, ordinary white copper, aluminum white copper and zinc white copper. Due to the different contents of the Ni element, their properties are different and their applications are also different. Compared with traditional alloys, it has unparalleled corrosion resistance and excellent performance, thus having great potential in application fields.

Nickel copper alloy composition

The main components of copper nickel alloy include elements such as nickel (Ni), copper (Cu), iron (Fe), manganese (Mn), etc. The nickel content is in excess, providing excellent corrosion resistance and high-temperature stability; the copper content is 27.00% - 29.00%, enhancing conductivity and corrosion resistance; the iron content is 2.00% - 3.00%, increasing strength and corrosion resistance; the manganese content is 1.20% - 1.50%, improving processing performance and oxidation resistance; carbon (C) ≤ 0.30%, silicon (Si) ≤ 0.30%, sulfur (S) ≤ 0.03%, phosphorus (P) ≤ 0.010%.

Usage

The nickel-copper alloy is widely used in various fields due to its excellent corrosion resistance, high strength and good processing performance. Its specific applications include:

Marine engineering: used in seawater desalination equipment, marine propellers, seawater desalination equipment, etc.

Petrochemical industry: used in heat exchanger tubes, reactor linings, etc.

Electric power industry: used in nuclear power condensers, high-voltage cable sheaths, etc.

Aerospace industry: used in hydraulic system components, engine parts, etc.

Electronic field: used in electrodes, conductive springs, and corrosion-resistant heat dissipation components, etc.
