Unalloyed nickel combines good mechanical properties with good corrosion resistance. In application temperatures above
300°C (572°F), Nickel 201, which stands out for a low C-concentration, is preferable over Nickel 200. The
lowered C-concentration reduces strength and the work hardening rate, and it raises ductility.

Typical applications are:

• Food manufacturing such as handling of cooling brine, fatty acids and fruit juices due to the material’s resistance against acids.
• Alkalis and neutral salt solutions and against organic acids.
• Tanks in which fluorine is produced and where it reacts with hydrocarbon (CFC) due to the material’s resistance against fluorine.
• Storage and transport of phenol.
• Production and treatment of caustic soda.
• Production of synthetic fibres and soaps.
• Production of hydrogen chloride and chlorination of hydrocarbons such as benzene, methane and ethane.
• Production of vinyl chloride monomer due to the material’s resistance against dry chlorine gas and hydrogen chloride in increased temperatures.
• Electrical and electronic components.
• Electrode contacts and current conductors in batteries.
• Current conductors in alkali fuels.

Nickel 200 and Nickel 201 are unalloyed nickel with a nickel concentration of at least 99.2%. Nickel 201 is the low carbon version of Nickel 200.

They are characterized by:

• Excellent resistance in alkaline media.
• High ductility in a wide temperature range.
• Ferromagnetism.
• High electrical and thermal conductivity.

The use of the following fillers is recommended for gas-shielded welding methods:
