TANTALUM FINISHED 

Tantalum alloy

 

Tantalum is dark, dense, ductile, very hard, easily fabricated, and highly conductive of heat and

electricity. The metal is renowned for its resistance ,as the metal powder, is in the production of

electronic components, mainly capacitors and some high-power resistors.
