How is the wear resistance and corrosion resistance of Copper-Nickel Alloy Materials?

As an important alloy material, Copper-Nickel Alloy has been widely used in many fields for its excellent wear resistance and corrosion resistance. From marine engineering to electronic equipment, from chemical equipment to shipbuilding, copper-nickel alloys are favored for their unique properties.
Wear resistance is the ability of a material to resist wear and is one of the important indicators for measuring the service life of a material. Copper-Nickel Alloy exhibits good wear resistance due to its unique alloy composition and microstructure. During friction and wear, a dense oxide film can be formed on the surface of the copper-nickel alloy, which can effectively reduce further wear and thus extend the service life of the material.
NiCu30Fe (2.4360): This is a high-copper alloy, commonly known as Copper-Nickel Alloy 70/30. Its high copper content (28.0-34.0%) and nickel content (≥63.0%) give it good wear resistance. In marine and coastal engineering, such as ship cooling and drainage systems, seawater desalination equipment, etc., NiCu30Fe alloy is highly regarded for its wear resistance.
C96200 copper-nickel alloy: This alloy material is mainly composed of copper (84.5-87.0%) and nickel, with high strength and hardness, and also has good wear resistance. In the fields of ships, chemical equipment and marine engineering, C96200 alloy can withstand long-term seawater erosion and corrosion due to its wear resistance, thereby extending the service life of the equipment.
Corrosion resistance refers to the ability of a material to resist corrosion in a specific environment. Copper-Nickel Alloy is widely used in many fields due to its excellent corrosion resistance. The infinite solid solution characteristics of copper and nickel make the alloy not undergo phase change in later processing, thereby maintaining its excellent corrosion resistance.
NiCu30Fe (2.4360): This alloy is known for its excellent corrosion resistance and is particularly suitable for applications in seawater and salt spray environments. Its high nickel content and moderate copper content make the alloy perform well in seawater and corrosive environments, and it is not easily affected by corrosion and oxidation.
Ordinary white copper (such as BFe10-1-1 and BFe30-1-1): These alloys have good resistance to seawater erosion and corrosion and are called "marine engineering alloys". They not only have high heat transfer coefficients and excellent mechanical/welding properties, but also effectively inhibit the attachment of marine microorganisms, so they are widely used in cooling water pipes for main and auxiliary engines of ships, fire protection pipelines of offshore oil production platforms, etc.
Manganese white copper (such as BMn3-12): Although its main use is not directly for corrosion resistance, manganese white copper has a low resistance temperature coefficient and good electrical properties. When making standard resistors and other resistance elements of precision instruments, it also indirectly reflects the importance of its corrosion resistance.
Application field
Copper-Nickel Alloy has been widely used in many fields due to its excellent wear resistance and corrosion resistance:
Marine engineering: including shipbuilding, seawater cooling systems, seawater desalination equipment, etc. These applications require materials to maintain stable performance in long-term seawater erosion and corrosion environments.
Chemical equipment: In the chemical industry, many equipment need to handle corrosive media, such as acids and alkalis. Copper-Nickel Alloy is competent for these tasks due to its excellent corrosion resistance.
Electronic equipment: In the electronic and electrical fields, Copper-Nickel Alloy is used to manufacture cable shielding, electrical connectors, battery terminals and other components due to its good conductivity and corrosion resistance.
Other fields: Such as the food industry, medical equipment, etc., these fields have strict requirements on the corrosion resistance and safety of materials, and Copper-Nickel Alloy is widely used due to its excellent performance.
