Nickel 200/201

PRODUCTION DESCRIPTION

Black Annealed Wire is also called black iron wire, soft annealed wire, and annealed iron wire. It includes annealed wire and black oiled wire. Black annealed iron wire gets its name from its plain black color.

Nickel 200/201

CLASSIFICATION:

Alloy wire,Coated wire,High carbon iron wire,Low carbon steel wire

Chinese Standard Grade:

Nickel 200/201

Ni200 pure nickel alloy has a slightly lower nickel content than Ni201, in which the content of Ni and Co is greater than 99.5%, and the content of other impurities is not higher than 0.5%. Ni200 has the characteristics of acid and alkali resistance, especially its outstanding alkali corrosion resistance, which makes it the main raw material for making various strong alkali resistance equipment. At the same time, it also has excellent corrosion resistance to salt media such as carbonate, nitrate, sulfate, chloride and acetate. In addition, it also has good processing performance, high electric vacuum performance, and stable performance in the atmosphere, fresh water and sea water. Therefore, Ni200 is widely used in batteries, alkali production, chemical industry, mechanical and electronic industries, etc. Its strong anti-corrosion ability makes it indispensable in materials such as food, rayon and caustic that need to ensure product purity.
