Tantalum Wire

Tantalum Wire basic information

Tantalum wire, Tantalum alloy wire Grade: RO5200, RO5252, RO5255 Size: Dia0.3~4mm Standard:ASTM B 365-98

Purity: ≥99.95g/cm³.

Condition: annealed.

Tantalum wire is a wire-like tantalum material made of tantalum powder as raw material by plastic processing methods such as rolling and drawing. 

Tantalum wire is used the most in the electronics industry and is mainly used for anode leads of tantalum electrolytic capacitors.

Raw material (tantalum powder) → mixing → forming → vertical melting → rotary forging → intermediate annealing → drawing → finished annealing → quality inspection → packaging and storage.

According to chemical purity, it is divided into 3 categories: 

(1) Metallurgical tantalum wire, purity 99.0% Ta; 

(2) High purity tantalum wire, purity 99.0%~99.9% Ta;

(3) Ultra-high purity tantalum wire, purity 99.9%~99.99 %Ta.

(1) Chemical corrosion-resistant tantalum wire; 

(2) High temperature and high-strength tantalum wire;

(3) Oxygen-resistant and brittle tantalum wire; 

(4) Capacitor tantalum wire.

(1) soft state (M), tensile strength σb=300~600MPa; 

(2) semi-hard state (Y2), tensile strength σb=600~1000MPa; 

(3) Hard state (Y), tensile strength σb>1000MPa.
