Purity: ≥99.95%,99.99%
Implementation standard: ASTM B365 ASTM F560
Density: 16.67g/cm3
High oxygen resistant brittle tantalum wire can also be used to make tantalum foil capacitors, which can be operated in potassium dichromate and sulfuric acid energizing solution at a high temperature of 772 (100℃) and extremely high flash voltage (350V). It is used to compensate muscle tissue, suture nerves and tendons, and make blood vessel stents and other heating parts of vacuum high temperature furnace. Used as a vacuum electron cathode emission source, ion sputtering and spraying materials.

Application:
Capacitor grade tantalum wire is mainly used to make anode leads of tantalum electrolytic capacitors. The smallest tantalum wire is Φ0.10mm. Tantalum wire is the key material for making tantalum capacitors. Tantalum capacitors are the best capacitors. About 65% of the world's tantalum is used in this field.

Detection:
Chemical composition testing
Mechanical performance testing
Inspection of appearance quality
Electrical performance testing
Packing:
Tantalum wire is wrapped with pearl cotton and then packed in wooden box. Our reasonable packing method can avoid the collision and damage of tantalum wire during transportation, and also prevent the impact of external goods on the product, so as to ensure the integrity of the product in the delivery process after leaving the factory.
