Sputtering gun barrels:
Computer disk manufacturers and other industries using sputtering processes are increasingly adopting tantalum to resist corrosion in sputtering gun barrels.
Machined fasteners:
Machined fasteners fabricated from tantalum offer superior corrosion resistance. They replace fasteners made of alternative materials prone to failure or that require expensive equipment shutdowns for maintenance.
X-ray/radiation shielding:
Tantalum's radio-opaque qualities make it ideal for X-ray and shielding applications seeking to prevent radiation leakage.
Vacuum furnace heating elements:
Because of tantalum's oxidation resistance and high melting point, many vacuum furnace components incorporate tantalum bars.
Machined parts for chemical processing equipment:
Tantalum's corrosion-resistant properties make it a choice material for machined parts used in chemical processing equipment.
