Product Details

Tantalum Wire Products Standard

Firmetal is also the sole supplier of powder metallurgical grade Tantalum 7.5% Tungsten (Ta7.5W), Tantalum 10% Tungsten (Ta10W) and Tantalum 40% Niobium (Ta40Nb) wire. Our products follow ASTM 365 standard.

Tantalum Wire Production Technology

  • Tantalum powder as raw material is processed into tantalum wire through rolling, drawing and other plastic processing working. The majority of tantalum wire is used in tantalum electrolysis and anode connection in the field of electronic industries.

  • Powder Metallurgy Method:Process: raw material (tantalum powder) → mixing → forming → fusion → rotary swaging → intermediate annealing → drawing → final annealing → inspection → packing

  • Smelting Method:Process: raw material (tantalum powder) → mixing → forming → pre-sintering → electron-beam smelting → precision forging → intermediate annealing → rotary swaging → intermediate annealing → drawing → final annealing → inspection → packing
