Alloy 405, also widely known as Monel R-405 and UNS N04405, is a specially optimized nickel-copper solid solution alloy developed for high-efficiency mechanical processing. Unlike heat-treatable high-strength alloys, Monel 405 cannot be hardened through heat treatment. Its mechanical strength can only be improved by cold working, which ensures stable and consistent material performance during mass production. As a professional and reliable Chinese nickel alloy supplier, ZYTC Alloy provides high-purity, stable-quality Alloy 405 bar stock tailored for automatic screw machine manufacturing and industrial corrosion-resistant components.
