Tantalum fabricated sheets and plates |
- Chemical process equipment including lining, cladding, tanks, valves, heat exchangers |
Superior corrosion resistance - equivalent in performance to glass |
|
Tantalum fabricated sheets, plates, rods, wires |
- Prosthetic devices for humans - hip joints, skull plates, mesh to repair bone removed after damage by cancer, suture clips, stents for blood vessels |
Attack by body fluids is non-existent; highly bio-compatible |
|
Tantalum fabricated sheets, plates, rods, wires |
- High temperature furnace parts |
Melting point is 2996°C although protective atmosphere or high vacuum required |
|
Tantalum ingot |
- Sputtering targets |
Applications of thin coatings of tantalum, tantalum oxide or nitride coatings to semi-conductors to prevent copper migration |
|
Tantalum ingot |
- High temperature alloys for: |
Alloy compositions containing 3-11% tantalum offer resistance to corrosion by hot gases, allow higher operating temperatures and thus efficiency and fuel economy |
|
Tantalum ingot |
- Computer hard drive discs |
An alloy containing 6% tantalum has shape memory properties |
|
Tantalum ingot |
- Explosively Formed Projectile for TOW-2 missile |
Balance of density and formability allow for a lighter and more efficient system |
