Permissible variations in diameter for rods and wires
Jul 03, 2017

The product of tantalum wire is highly ductile, very hard, easily fabricated, conductive of heat and electricity; resistant to corrosion by acids, has high melting point of 3017 °C. The diameter range from 0.09mm to 10mm, product capability is 2 tons per month.

The tantalum production of our company is remarkable for its flexible technology of processing of any kinds of tantalum raw materials into high quality. This technology allows manufacturing products with the set quality parameters. Our major products are tantalum wire. We also produce tantalum as mesh, sheet, vessels and other shapes are available by request. 


Tantalum wire is highly conductive of heat and electricity. It is renowned for its resistance to corrosion by acids. The major use for tantalum wire is in the production of electronic components, mainly capacitors and some high-power resistors. We offer all the normal sizes and customer specific (Non standard) sizes for various purposes in any industry.
