Tantalum is dark (blue-gray), dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. It is extremely inert and is therefore formed into a variety of corrosion resistant parts. In addition, tantalum tubes can work under 1500°C. After that, the high melting point and oxidation resistance lead to the use of the metal in the production of vacuum furnace parts. We provide various dimensions with strict tolerance, and purity is up to 99.95% and 99.99% at your choice. Our tantalum material is from Non-Conflict Resource.
Application: Tantalum response vessel, tantalum heat exchangers and etc.
