Nickel Tube

Nickel Tube is a seamless metallic tube available in purities from 99% (2N) to 99.5% (2N5), in as-drawn, annealed, and hard tempers, combining excellent corrosion resistance with retained strength and ductility under mechanical and thermal load. With a melting point of 1453 °C, thermal conductivity of 90.9 W/m·K, and tensile strength ranging from 400 MPa in the soft condition to 660 MPa in the hard condition, it delivers a reliable balance of thermal performance and mechanical robustness across its full temper range. Its face-centered cubic structure and good toughness support reliable performance under cyclic mechanical and thermal stress, while its resistance to corrosion in acidic and high-temperature conditions extends service life in aggressive chemical environments where many other metals would degrade. The choice of temper allows the tube to be matched to the application: as-drawn and hard tempers provide maximum mechanical strength and dimensional rigidity for structural and high-pressure applications, while annealed tube offers greater ductility for forming, bending, or coiling operations. Typical applications include chemical processing equipment handling caustic and acidic media, heat exchanger tubing where thermal conductivity and corrosion resistance must be combined, oil and gas pipeline components, and vacuum apparatus requiring a clean, outgassing-resistant metallic conduit. Its purity range and temper options also support precision laboratory and instrumentation applications where reproducible mechanical and thermal behavior is required.
