Description
Superior Nickel 201 Wire – High-Purity 99.6% Alloy for Industrial Use
📖 Product Overview
The nickel 201 wire is a high-purity, commercially pure wrought nickel alloy containing at least 99.6% nickel. Known for its outstanding corrosion resistance, exceptional mechanical stability, and impressive heat resistance, it is a preferred choice for demanding industrial, chemical, and scientific applications.
Manufactured to precise industry standards, this high purity nickel wire offers excellent ductility, weldability, and formability, making it suitable for use in electronics, chemical processing equipment, marine environments, and heat-treating operations. Its low carbon content (<0.02%) ensures improved resistance to graphitization and better performance in high-temperature and reducing environments compared to Nickel 200.
Whether used for intricate electrical connections, thermal resistance components, or chemical-resistant apparatus, the pure nickel wire delivers consistent, reliable performance under the most challenging conditions.
🧪 Chemical Composition (Nickel 201 – ASTM B160 / UNS N02201)
