Classification:

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%~99 %Ta.

Divided into 4 categories according to performance: (1) Chemical corrosion-resistant tantalum wire: (2) High temperature and high-strength button wire; (3) Oxygen-resistant and brittle tantalum wire; (4) Capacitor button wire.

Capacitor tantalum wires are divided into three categories according to their use: (1) Tantalum wires for solid tantalum electrolytic capacitor leads; (2) Tantalum wires for liquid tantalum electrolytic capacitor leads; (3) Tantalum wires for capacitor claws with reliability indicators.

According to the state of the capacitor tantalum wire, there are 3 categories: (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.

Application:

Tantalum wire is mainly used to make anode leads of tantalum electrolytic capacitors. The capacitor grade tantalum wire currently produced by Tantalum Niobium can be divided into more than 30 varieties according to different states and different specifications. The smallest diameter tantalum wire is Φ0.10mm, and it can also be made into tantalum yarn or tantalum mesh. Tantalum wire is the key material for making tantalum capacitors. Tantalum capacitors are the best capacitors. About 65% of tantalum in the world is used in this field. Used to compensate for muscle tissue, and can be used to suture nerves and tendons. Tantalum-niobium can provide tantalum wire in different states and specifications. The smallest diameter tantalum wire is medium Φ0.1mm. Tantalum wire can also be used to make heating parts for vacuum high temperature furnaces.

Tantalum wire is used the most in the electronics industry and is mainly used for anode leads of tantalum electrolytic capacitors. The high resistance to oxygen and brittle tantalum wire can also be used to make tantalum foil capacitors. It can be used in potassium dichromate and sulfuric acid energizing liquid, under the conditions of high 772 temperature (100°C) and extremely high flash voltage (350V). In addition, tantalum wire can also be used as a vacuum electron cathode emission source, ion sputtering and spraying materials, etc.
