Tantalum Wire​ Mainly For Tantalum Electrolytic Capacitor Anode Lead.

2024-01-05 18:00:06

Tantalum wire is tantalum powder as raw material by rolling, drawing and other plastic processing method made of a filamentous tantalum material. Tantalum wire in the electronics industry on the largest amount, mainly for tantalum electrolytic capacitor anode lead.


Tantalum wire can be classified according to its chemical purity properties, use and status.

(1) high purity tantalum wire, purity 99.0% ~ 99.9% Ta; (2) ultra-high purity tantalum wire, purity 99.9% ~ 99.99 (3) metallurgical tantalum wire, purity 99.0% Ta; % Ta.

According to the performance is divided into four categories: (1) chemical corrosion tantalum wire; (2) high temperature and high strength tantalum wire; (3) anti-oxidation crisp tantalum wire; (4) capacitor tantalum wire.

(1) solid tantalum electrolytic capacitor lead with tantalum wire (TalS, Ta2s) (see Chinese national standard GB / T3463-1995); (2) liquid tantalum electrolytic capacitor lead with tantalum wire ( (See Chinese National Standard GB / T3463-1995); (3) Tons of tantalum (DTals, DTalL) for reliability indicators (see National Military Standard GJB2511-95).

(1) soft state (M), tensile strength σb = 300 ~ 600MPa; (2) semi-hard (Y2), tensile strength σb = 600 ~ 1000MPa; (3) Hardness (Y), tensile strength σb> 1000MPa.
