Nickel 201 (Ni 201), also known as Alloy 201 with UNS N02201 and W.Nr. 2.4068, is a high-purity nickel alloy known for excellent corrosion resistance, particularly in alkaline environments and organic acids. This alloy is ideal for chemical processing, aerospace, and food processing applications, offering strong resistance to high temperatures and stress corrosion cracking.
With good weldability and formability, Nickel 201 is widely used in the manufacturing of components such as heat exchangers, electrical components, and precision instruments. Its resistance to corrosion and excellent mechanical properties make it a reliable choice for harsh environments requiring high-performance materials.
