Description
Tantalum is dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity and is featured the third highest melting point 2996℃ and high boiling point 5425℃. It has the characteristics of high temperature resistance, high corrosion resistance, cold machining and good welding performance. Therefore, tantalum and its alloy are widely used in electronics, semiconductor, chemical, engineering, aviation, aerospace, medical, military industry etc. It can be found in cell phones, laptops, game systems, automotive electronics, light bulbs, satellite components and MRI machines.
