NICKEL201 UNS N02201 Pure Nickel Alloy Wire Excellent Corrosion Resistance for

Product Specification

Nickel 201 (UNS N02201) is a commercially pure wrought nickel alloy with a nickel content of over 99%. It is essentially the same as Nickel 200, but with a significantly lower carbon content (max 0.02%), which prevents intergranular embrittlement at temperatures above 315°C (600°F). The lower carbon content also reduces hardness, providing excellent ductility and making it ideal for cold forming, spinning, and applications requiring sustained exposure to temperatures up to 1260°C. Nickel 201 exhibits outstanding resistance to a wide range of reducing chemicals, caustic alkalis, and neutral/alkaline salt solutions. It is ferromagnetic at room temperature and offers excellent electrical and thermal conductivity.

Rating: ★★★★★ = Excellent, ★★★★☆ = Very Good, ★★★☆☆ = Good, ★★☆☆☆ = Fair. Data for reference at ambient temperature unless otherwise noted.

• Excellent Corrosion Resistance: Outstanding resistance to reducing chemicals, caustic alkalis (NaOH, KOH), and neutral/alkaline salt solutions. Resistant to distilled and natural waters.
• High Electrical & Thermal Conductivity: Superior electrical conductivity (0.096 Ω·mm²/m resistivity) and thermal conductivity (79.3 W/mK), making it ideal for electrical and heat transfer components.
• Low Carbon Content: Max 0.02% carbon prevents intergranular embrittlement at elevated temperatures above 315°C, enabling reliable high-temperature service.
• Excellent Ductility: Low work hardening rate allows extensive cold forming, deep drawing, and spinning without intermediate annealing.
• Good Weldability: Readily weldable by GTAW (TIG), GMAW (MIG), SMAW, and resistance welding with proper Nickel 201 filler metals.
• Ferromagnetic: Exhibits ferromagnetic behavior at room temperature (Curie temperature ~360°C), suitable for magnetic applications.
• High Purity: ≥99% nickel ensures contamination-free processing, critical for food and pharmaceutical applications.
• Wide Temperature Range: Serviceable from cryogenic temperatures up to 1260°C in appropriate environments.
