Pure nickel / nickel-chromium alloy-(1)

Pure nickel / nickel-chromium alloy-(1)

Pure nickel (Nickel 200/201) possesses extremely high purity (≥99%), exhibiting excellent resistance to alkali and reducing media corrosion in caustic soda, chlor-alkali, fluorochemical, and food processing equipment. It also boasts good thermal and electrical conductivity and processing performance, making it an ideal material for the chemical and electronics industries. Our company supplies a full range of pure nickel and nickel-chromium products (plates, bars, tubes, wires, strips) in various forms, supporting small-batch trial orders. We leverage major ports for efficient delivery, providing reliable materials for harsh chemical environments and high-temperature electrothermal applications.

Moderate corrosion resistance at room temperature.
Key FeaturesPure Nickel:High electrical/thermal conductivity; good mechanical properties and formability; ferromagnetic below 358℃; outstanding corrosion resistance in caustic and reducing media; low vapor pressure (suitable for vacuum service); service temperature up to 315℃ (Nickel 200) or higher (Nickel 201, up to 600℃ due to lower C).Ni-Cr Alloy:High resistivity, low temperature coefficient of resistance, excellent high-temperature oxidation resistance, thermal fatigue resistance, stable electrical performance.
Main ApplicationsPure Nickel:- Chemical: Caustic evaporators, reactors, tanks, piping; chlor-alkali equipment; fluorine chemical plants.- Electronics: Battery electrodes (Ni-Cd, Ni-MH), lead wires, EMI shielding.- Food/Pharma: Food processing equipment, caustic washing vessels.- Aerospace: Igniter tips, high-temperature cable sheathing.- Others: Coinage, electroplating anodes, catalyst supports.Ni-Cr Alloy:- Heating elements: Industrial furnaces, domestic appliances, ovens, air heaters.- Resistors: Precision resistors, rheostats, potentiometer windings.- High-temperature structural parts: Muffle furnace liners, radiant tube supports.- Welding/Spraying: Filler metals for stainless steel and Ni-based alloys.
Fabrication & WeldingHot Forming:Pure nickel: 870-1230℃, finish ≥870℃; similar for NiCr. Protective atmosphere recommended.Cold Forming:Pure nickel has excellent ductility, low work hardening rate; intermediate annealing generally not required.Welding:TIG, MIG, resistance welding, brazing. Filler: ERNi-1 or ERNiCu-7 for pure nickel; matching NiCr filler or ERNiCr-3. Clean surface, avoid sulfur/lead contamination.
