Manufacturing Process And Application Of Tantalum Wire

2024-01-05 18:00:06

  Tantalum wire is a kind of filamentary tantalum material made of powder by rolling and drawing.

 

  Manufacturing process:

  Powder metallurgy method

 The technological process is as follows: raw material (tantalum powder) mixture molding vertical melting rotary forging intermediate annealing drawing finished product annealing quality inspection packaging and storage.

   They can be classified according to their chemical purity and properties.

 

   According to chemical purity, it can be divided into three categories: (1) metallurgical tantalum wire with 99.0% Ta, (2) high purity tantalum wire with 99.0% ~ 99.9% Ta, (3) ultra-high purity tantalum wire with 99.9% ~ 99.99% Ta.

 

   According to their properties, they can be divided into four categories: (1) chemical corrosion-resistant tantalum wire; (2) high-temperature and high-strength wire; (3) oxygen-resistant brittle wire; (4) capacitor wire.

 

   Product attributes:

   Trademarks: Ta1, Ta2, TaW2.5, TaW7.5, TaW10, TaNb3, TaNb20, TaNb40, etc.

   Standard: GB / T3463 - 1995; Purity: Purity of tantalum is more than 99.95%; State: annealed (M) or hard (Y);

   Size: disc wire: 0.6~ 5mm 1.~, 3*L2m (Max)

   Use:

   Tantalum wiresare the most used in the electronics industry, mainly used for the anode lead of tantalum electrolytic capacitors. Tantalum foil capacitors can also be fabricated with high oxygen resistance and brittle tantalum wires. They can operate at high 772 temperature (100 C) and ultra high flash voltage (350V) in potassium dichromate and sulfuric acid energizing solutions. In addition, tantalum wires can also be used as vacuum electron cathode emission sources, ion sputtering and spraying materials.
