Nickel 205 N02205 Wire With High Purity For Marine And Aerospace Industries
Nickel 205 (N02205) Wire is a high-purity nickel alloy (minimum 99.9% nickel) designed for applications requiring excellent corrosion resistance, high thermal and electrical conductivity, and good mechanical properties. It offers superior resistance to alkalis, acids, stress corrosion cracking, and hydrogen embrittlement, making it ideal for use in harsh chemical environments. The wire exhibits moderate tensile strength, high ductility, and non-magnetic properties, ensuring reliability in sensitive electronic and industrial applications. Nickel 205 is easy to machine, weld, and fabricate, allowing it to be formed into fine wires or complex shapes. It performs well in elevated temperatures up to 600°C (1112°F) and is commonly used in electrical components, resistance wires, connectors, and chemical processing equipment. Its combination of high purity, durability, and excellent conductivity makes Nickel 205 a preferred material for demanding applications in electronics, aerospace, and chemical industries.
