Uses of Tantalum And Tantalum Alloys

Tantalum is a hard, lustrous transition rare metal and it is highly corrosion-resistant. Electrolytic capacitor making from tantalum has the advantages of large capacity, small size and good reliability, which makes it the most important use of tantalum. Tantalum is also the material for making electron emission tubes and high-power tube parts. 

The chemical inertness of tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. Tantalum alloys, tantalum-tungsten alloys, tantalum-hafnium alloys are used as heat-resistant and high-strength materials for rockets, missiles and jet engines, as well as parts for control and regulation equipment. 

Tantalum carbide is an extremely hard (Mohs hardess 9-10) refractory ceramic material. The hardness is only exceeded by diamond. Tantalum borides, silicides and nitrides and their alloys are used as heat release elements and liquid metal cladding materials in the atomic energy industry. Cerium oxide is used in manufacturing advanced optical glass and catalysts. 

In 1981, the proportion of consumption of Tantalum in the United States was about 73% for electronic components, 19% for machinery industry, 6% for transportation, and 2% for others.

Nowdays, refractory metal is widely used in every areas, if you have any question, please feel free to contact us.
