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.
