Tantalum wire is a kind of filamentous tantalum material made from tantalum powder by rolling, drawing and other plastic processing methods. Tantalum wire is widely used in electronic industry and is mainly used as anode lead of tantalum electrolytic capacitor.
Brand: TA1, TA2, taw2.5, taw7.5, taw10, tanb3, tanb20, tanb40, etc
Manufacturing method of tantalum wire
1.Powder metallurgy
The technological process is as follows: raw material (tantalum powder) → mixing → forming → vertical melting → rotary forging → intermediate annealing → drawing → finished product annealing → quality inspection → packaging and warehousing.
2.Smelting process
The technological process is as follows: raw material (tantalum powder) → mixing → forming → pre sintering → electron beam melting → precision forging → intermediate annealing → rotary forging → intermediate annealing → drawing → annealing of finished products → quality inspection → packaging and warehousing.
Mechanical property
Main uses of tantalum wire
The smallest diameter of tantalum wire is Φ 0.10 mm. It can also be made into tantalum yarn or tantalum mesh. Tantalum wire is the key material for tantalum capacitor. Tantalum capacitor is the best capacitor. About 65% of tantalum in the world is used in this field.
