0.54mm, DIN200 Spool, NiMn2, NiMn3, NiMn5 Pure Nickel Manganese Alloys wire / Stranded wire
Nickel 201 is a low carbon variety compared with Nickel 200, possessing low annealed hardness and a very low work-hardening rate, desirable for cold forming operations. It is highly resistant to corrosion by neutral and alkaline salt solutions, fluorine and chlorine, but in oxidising salt solutions severe attack will occur.
The applications of pure nickel includes food and synthetic fiber processing equipment, electronic parts, aerospace and missile components, handling of sodium hydroxide above 300℃.

Description
Manganese compounds have been used by man for thousands of years. The ancient Egyptians and Romans used manganese compounds for dyeing in glass manufacture. In 1774 Johann Gottlieb Gahn succeeded in extracting pure manganese from brownstone. In the structure of the earth's crust manganese is the second most common heavy metal after iron.
Important manganese ore deposits are to be found in South Africa, Australia, India, China, Mexico, Ukraine and Russia amongst others.
"Manganese nodules" can also be found in the deep sea.

Manganese is a grey-white, hard heavy metal. In the air it remains stable by the formation of an oxide film.

Application
Due to its high affinity to sulphur and oxygen it is a vital element for the metal industry.
About 90 to 95% of the produced amount, preferably ferromanganese is used in the iron and steel industry
1. for deoxidizing and desulphuring iron and steel
2. as nickel substitute in corrosion-proof stainless steels
3. as strength-increasing alloy element for steels
