Tantalum Mill Products

TANTALUM SHEET, PLATE, ROUND DISK AND FOIL

H.C. Starck’s tantalum sheet and foil are popular for chemical processing applications, where customers can convert it into lining for columns, vessels, tanks, reactors, parts for heat exchangers, and more.

Customers transform our tantalum plate into products for military, chemical processing, and other anti-corrosion type applications.

Both tantalum sheet and plate are used by customers in the manufacturer of components for anticorrosion equipment. Round discs cut from tantalum plate are employed to repair and reinforcement work in anti-corrosion equipment.

Because of their strength and workability, very thin sheets of tantalum can be clad to other surfaces, providing superior corrosion protection and cost effectiveness.

Our tantalum sheet and plate are supplied with a cold-rolled and chemically cleaned surface. The sheet and plate may be locally conditioned to remove defects, provided that thickness tolerance is maintained.

Depending on your specifications and needs, all of our tantalum sheet, plate, and foil are visually inspected for slivers, laminations, excessive roll marks and handling scratches.

ULTRA76 Ta alloys offer higher corrosion resistance in most environments generating value added by extending product life time, reducing material thickness and improving processes throughput.

  • Higher temperatures possible, shorter cooling/heating cycle times
  • Constant surface finish (Ra<0.8 micrometers)
  • Material only from non-conflict sources, H.C. Starck is EICC certified
  • Uniform wall thickness
  • Best flatness for explosion clad applications
