Nickel 200
UNS N02200 EN / W.Nr. 2.4060 / 2.4066
99.0% minimum commercially pure nickel — caustic-alkali processing, food-handling equipment and electronic leads. Not used above about 315 °C where graphitisation occurs.
Nickel Alloys — Pure Nickel & The Alloy Family
Commercially pure nickel for chemical and electronic duty, plus the gateway to the full nickel-alloy family — Monel, Inconel, Incoloy and Hastelloy.
Nickel Alloys — Material Overview
Nickel is the base of the most corrosion- and heat-resistant engineering metals. Commercially pure Nickel 200/201 combines good corrosion resistance (especially to caustic alkalis) with outstanding thermal and electrical conductivity and magnetostrictive properties.
The wider nickel-alloy family is organised on its own pages here: Monel (nickel-copper, seawater and hydrofluoric acid), Inconel & Incoloy (nickel-chromium and nickel-iron-chromium, for heat and oxidation resistance), and Hastelloy (nickel-molybdenum, for the strongest acids and the most aggressive chemical duty).

Frequently Asked Questions
What is the difference between Nickel 200 and 201?
Nickel 201 is the low-carbon (≤ 0.02%) version of 200. Above roughly 315 °C, Nickel 200 can precipitate graphitic carbon that embrittles it, so 201 is specified for elevated-temperature service.
Where is pure nickel actually used?
Its two stand-out duties are caustic-alkali service (it resists sodium and potassium hydroxide better than almost any common metal) and electronic/lead applications that exploit its conductivity and magnetostriction.
Which nickel alloy should I choose for seawater?
Monel 400 and nickel-copper alloys are the classic seawater choice — see the Monel page. For hot chloride or sour service, Inconel 625 and Hastelloy C276 are the usual answers.
Do you supply all nickel alloys or only pure nickel?
This page covers pure nickel; the alloy families each have their own page — Monel, Inconel and Incoloy, and Hastelloy — with grades, compositions and product forms. Enquire for anything not listed.
