Tantalum Foil (Ta Foil)
Edgetech Industries LLC provides high purity tantalum foil to universities, research labs and manufacturing companies. Tantalum and tantalum alloys products are also avaibale in forms of sheet, plate, wire, rod, ribbon, pellets, powder, sputtering targets, disc and cusomized parts per drawings.
We provide Tantalum foil with 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
Pure Tantalum Grades
R05200, unalloyed tantalum, electron-beam furnace or vacuum-arc melt
R05400, unalloyed tantalum, powder-metallurgy consolidation.
We guarantee the purity of 99.95% for our sintered quality tantalum (metallic purity without Nb) with bother melted tantalum (R05200) & sintered tantalum (R05400). Our sintered tantalum is used for those tricky situations: due to our powder metallurgy production process, sintered tantalum is particularly fine-grained. As a result, the material is very easy to work with and excels due to its excellent surface quality and robust mechanical properties. Melted tantalum is usually more economical to produce than sintered tantalum and provides sufficient quality for many applications. However, the material is neither as fine nor as homogeneous as R05400 tantalum. They both work excellently in different fields.
Pure sintered and melted tantalum share the following properties:
-High melting point of 2996 °C
-Good cold ductility
-Recrystallization between 800 °C and 1200 °C (depending on the level of deformation and purity)
-Outstanding resistance against aqueous solutions and metal melts
-Superconductivity
-High level of biocompatibility
