Quick Answer: What Is N6 Nickel?
N6 (GB/T 5235 / Ni 99.5) is the standard commercial-purity wrought nickel, providing >=99.5% Ni+Co at the most economical price point in the pure nickel spectrum. It is the first-choice material for general alkaline corrosion service, plating anodes where ultra-low iron is not specified, and cost-sensitive chemical equipment. Shanghai Hangbo Alloy Group supplies N6 as round bars, plates, and cold-rolled strip.

Product Overview
N6 is the entry-level pure nickel grade under the GB/T 5235 classification system, equivalent to the purity of standard electrolytic nickel cathode. It is the most widely produced and consumed pure nickel wrought product in China, used extensively for caustic soda handling equipment, nickel plating anodes, and alkali-resistant chemical process components.
While its higher iron and carbon content make it marginally less corrosion-resistant than N4 or N5 in the most aggressive alkaline conditions, N6's cost advantage (typically 10-20% lower than N5) makes it the default choice for general corrosion service.
N6 vs NI200 comparison: N6 (>=99.5% Ni) is the Chinese standard equivalent to the Western NI200 (>=99.0% Ni), with N6 actually having a slightly higher minimum nickel content. For international procurement, N6 and NI200 are generally interchangeable.

FAQ
Q1: N6 vs N5 vs N4? Purity: N4(99.9) > N5(99.8) > N6(99.5). Cost: N6 is 10-20% cheaper than N5. Choose N6 for general alkaline service; N4 for high-purity applications.
Q2: N6 vs NI200? N6 >=99.5% Ni; NI200 >=99.0%. N6 has slightly higher minimum purity. Functionally interchangeable.
Q3: Price? $20-35/kg EXW. Most economical pure nickel grade. Contact sales@hangboalloy.com.
Q4: Forms? Bars(6-200mm), plates, cold-rolled strip, wire. SGS available.
