Tantalum Plate

Category:

Edgetech Industries LLC can furnish tantalum plate and tantalum tungsten alloy plate, tantalum niobium alloy plates with 2000mm maximum length.

Tantalum has a melting point exceeded only by tungsten & rhenium. Major use for tantalum is in the production of electronic components, mainly capacitors and some high-power resistors. Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer. The dielectric layer of tantalum capacitor can be very thin, a high capacitance can be achieved in a small volume. Tantalum capacitors are attractive for cell phones, computers, and automotive electronics for its size and weight advantages. Due to its high melting point and oxidation resistance tantalum is used in the production of insulation barriers in vacuum furnaces. Since it resists attack by body fluids and is nonirritating, tantalum is widely used in making surgical instruments and implants. For example, porous tantalum coatings are used in the construction of orthopedic implants due to its ability to form a direct bond to hard tissue.

We provide tantalum plate with following dimensions and specifications:
Specification: ASTM B708
Material: R05200, R05400, Ta-Nb3, Ta-Nb20, Ta-2.5W (R05252), Ta-10W
Size: 5.0-10.0mm Thick x 30-1000mm width x < 2000m L

We also provide thicker tantalum, as tantalum block.

Packing information for our Tantalum Plate

Our tantalum plates are mostly packed in wooden crates, this can protect the tantalum plate during transportation and handling. Carton is used for small pieces of tantalum plates.

Specification for different tantalum & tantalum alloy products
Rod & Wire: ASTM B365
Plate, sheet, strip & foil: ASTM B708
ASTM F560-Unalloyed Tantalum for Surgical Implant Applications

We can also provide custom other tantalum products, please send us your request to sales@edge-techind.com for any needs on tantalum rolling products.
