Difference Between N4, N5, N6, Nickel 200 and Nickel 201

N4 vs N5 vs N6 vs Nickel 200 vs Nickel 201 Comparison Table

Pure nickel materials are widely used in chemical processing, alkali service, electronics, and heat-resistant industrial applications.
Among the most frequently searched grades are N4, N5, N6, Nickel 200, and Nickel 201.
Understanding the differences and relationships between these grades can help buyers, engineers, and distributors choose the right material for pipes, bars, plates, and other nickel alloy products.

Note: Nickel 200 and Nickel 201 are internationally recognized pure nickel grades.
N4, N5, and N6 are commonly used Chinese commercial pure nickel grades.
Their exact equivalence should be confirmed according to the applicable chemical composition and material standard.

Recommended Website Wording

N4, N5, and N6 are commonly used Chinese commercial pure nickel grades, while Nickel 200 (UNS N02200) and Nickel 201 (UNS N02201) are internationally recognized pure nickel grades.
Nickel 201 has lower carbon content than Nickel 200, making it more suitable for elevated-temperature applications.
N6 is often compared with Nickel 200 in the market, but the exact equivalence should be confirmed according to chemical composition and applicable standards.

Quick Relationship Summary

  • Nickel 200 = UNS N02200
  • Nickel 201 = UNS N02201
  • N4 / N5 / N6 are commonly used Chinese pure nickel grades
  • N6 is often compared with Nickel 200 in the market
  • The exact equivalent of N4 / N5 / N6 should be confirmed by standard and chemical composition
