Pure nickel (commercially wrought nickel) contains nickel ≥99.0 wt%, represented by Nickel 200 (UNS N02200) and low-carbon Nickel 201 (UNS N02201). It is not superalloy. Pure nickel excels in caustic alkali corrosion resistance and performs stably in reducing and neutral salt environments. It owns great ductility, formability, weldability plus high electrical and thermal conductivity. Nickel 200 suits service below 315°C, while Nickel 201 avoids graphitization embrittlement for elevated temperature working conditions.

Nickel 200
Nickel 200 (UNS N02200) is a commercially pure nickel alloy containing a minimum of approximately 99% nickel. Its key advantages include good resistance to caustic alkalis, excellent thermal and electrical conductivity, and good ductility and formability. Nickel 200 also offers useful resistance to neutral and reducing environments, making it suitable for chemical processing, food processing, electrical components, and caustic soda equipment. Compared with Nickel 201, its higher carbon content makes Nickel 200 more suitable for applications where elevated-temperature carbon-related limitations are not critical.
Nickel 201
Nickel 201 (UNS N02201) is a low-carbon version of commercially pure Nickel 200, with a significantly reduced carbon content. Its main advantage is improved resistance to graphitization and embrittlement during prolonged exposure to elevated temperatures. Nickel 201 retains the good corrosion resistance, ductility, thermal conductivity, and electrical conductivity associated with commercially pure nickel. It is particularly suitable for chemical processing equipment, caustic alkali service, electrical components, and applications where both corrosion resistance and low-carbon performance are required at elevated temperatures.
Process of Pure nickel
The production of pure nickel is a rigorous metallurgical process, primarily designed to secure high material purity and consistent corrosion resistance. Key steps include:
Vacuum Induction Melting (VIM): Melting nickel feedstock under vacuum conditions to eliminate gaseous impurities and precisely regulate chemical composition.
Electroslag Remelting (ESR): Refines molten nickel to reduce inclusions, minimize segregation and deliver uniform, clean metallurgical microstructure.
Hot Rolling & Cold Working: Deforms nickel ingots into plates, bars or tubes; cold working enhances strength, while subsequent annealing restores ductility for forming operations.
Surface Finishing & Heat Treatment: Controlled annealing relieves residual stress, and surface treatment removes oxides, delivering clean, smooth surfaces for corrosion service.
Through these production technologies, pure nickel retains its high purity and stable corrosion resistance, which are essential for chemical, electronic and marine critical applications.

Q:Can pure nickel resist corrosion? A: Pure nickel delivers exceptional corrosion resistance, particularly in caustic alkali environments. It also performs well against dry fluorine, chlorine and many non-oxidizing corrosive media.
Q:Is pure nickel suitable for high temperature use? A: Pure nickel can be used at moderate high temperatures. It maintains oxidation resistance but lacks the creep strength of superalloys, so it is not recommended for heavy-load high-temperature structural components.
Q:Can pure nickel be welded and formed? A: Yes. Pure nickel has excellent ductility. It can be cold stamped, deep drawn and welded with standard processes. Stress relief annealing is recommended after heavy forming operations.
Q:What are common product forms of pure nickel? A: Pure nickel is supplied as round bars, plates, sheets, seamless tubes, wires and foils. These semi-finished forms cover requirements for chemical, battery and electronic manufacturing.
