Tantalum Rod Bar/Wire Applications

Tantalum and tantalum alloy rods (such as Ta-2 5W, Ta-10W, Ta-40Nb etc.) have the characteristics of high melting point, corrosion resistance and good cold working performance. They are widely used in aviation and aerospace industry, high temperature technology, atomic energy industry and chemical industry, mainly used in the production of supersonic aircraft, rocket engine, spacecraft combustion chamber parts, high temperature resistant furnace parts, etc. Resistance to nitric acid, sulfuric acid, hydrochloric acid corrosion parts, etc.
