Features
* Good ductility
* Good plasticity
* Excellent acid-resistance
* High melting point, high boiling point
* Very small coefficients of thermal expansion
* Good capability of absorbing and releasing hydrogen
Application
Tantalum is used to produce various types of alloys with high melting point, strength and malleability.
By alloying with other metals, we can manufacture cemented carbide tools for metal processing, jet engine parts, chemical processing equipment, nuclear reactors, missile parts, heat exchangers, superalloys for tanks and containers, etc. Used for purposes.
