Nickel 201

Material: Nickel 201, UNS N02201, 2.4061, 2.4608
Nickel 201, also known as commercial pure nickel, nickel 201, UNS N02201, German standard grades are 2.4061, 2.4068. Nickel 201 material is mostly used in reducing media, and shows good corrosion resistance in many acidic and alkaline corrosive environments. In particular, it is resistant to corrosion in alkaline media, such as caustic potash and caustic soda, and is widely used in ion membrane caustic soda processes.

Nickel 201 Introduction:

Nickel 201 alloy is a pure nickel alloy with good performance and wide application. It has excellent acid resistance, salt resistance and alkali resistance. Nickel 201 has excellent caustic resistance and can even resist molten caustic corrosion.


Nickel 201 can maintain good thermal conductivity, electrical conductivity and mechanical properties. Because nickel alloy 201 has good strength and plasticity, it is widely used in industry. In addition to its value, pure nickel can be used as corrosion-resistant structural materials and functional materials due to its good properties. For example, according to the ASME Boiler and Pressure Vessel Code, Nickel 201 is approved for the construction of pressure vessels with working temperatures up to 1250°F.


JN Alloy has a large amount of imported spot inventory of nickel 201 material with complete material specifications and can provide original material guarantees. Welcome to consult.

Nickel 200 vs Nickel 201

The main difference between the two is the carbon content.


N02200: C% not more than 0.15; N02201: C% not more than 0.02.


Nickel200 has a relatively high carbon content and may be graphitized under high temperature conditions, which may impair product performance. Therefore, Nickel 200 is usually limited to use in environments below 600°F, while Nickel 201 is relatively more resistant to high temperatures and is approved for service at 1250°F.


Generally speaking, there is little difference in the corrosion resistance of the two, and Nickel201 is more resistant to intergranular corrosion during welding.


In terms of deep stamping performance, Nickel201 performs significantly better, so the ultra-thin nickel box used for electronic components and electronic products is made of Nickel201 and Nickel205 with higher standards.


Note: German VDM and other manufacturers control the carbon content to produce materials that meet the dual standards of 200 and 201 under general conditions, which are suitable for a wider range of application environments.
