Special require of tantalum wire to be agreed on by the supplier and buyer of negotiations.

Tantalum applications:

1) In devices for producing various inorganic acids , tantalum instead of stainless steel, tantalum devices’ life is stainless steel devices’ life many times.
2) in the chemical, electronic, electrical and other industries, tantalum instead of the precious metals platinum, costs is greatly reduced.
3) Tantalum is an important alloy element in smelting Super steel, corrosion resistant steel and heat-resistant steel.
4) Tantalum is used in modern medicine. Tantalum has no harm to the human body, and human muscle can grow on tantalum.
