Non-Ferrous Crucible Inc. provides high-purity tantalum foil and strips to universities, research labs, and manufacturing companies. Tantalum Niobium Alloy Foil is also available on request.
The width limit of foil is generally narrower than that of sheet and strip, and the size limits of rolled products are mutually restricted. This is related to the specifications of the rolling mill required for the corresponding thickness product.
We provide Tantalum foil with the following dimensions and specifications:
Specification: ASTM B708
Material: R05200, R05400, TaNb3, TaNb20, Ta2.5W (R05252)
Size: 0.01-0.09mm Thick x 30-150mm width x L, in roll
Surface: Cold rolling

Sintered and pure molten grades of tantalum have the following common properties:
-Melting point up to 2996 °C
-Good cold ductility
-Recrystallization between 800 °C and 1200 °C (depending on the degree of deformation and purity)
-Excellent resistance to aqueous solutions and metal melts
-Superconductivity
-High biocompatibility
Tantalum and its alloy products are also available in the form of sheets, plates, wires, rods, ribbons, pellets, powder, sputtering targets, and discs.
