Product Features in Detail

1. Corrosion resistance: Tantalum wire has good corrosion resistance and can be used in extreme environments. It has good corrosion resistance to most acids and bases, such as at 150 ° C, it will not corrode in any concentration of hydrochloric acid, nitric acid, phosphoric acid, and organic acids, but is sensitive to hydrofluoric acid and mixtures of hydrofluoric acid and nitric acid

2. Conductivity: Tantalum wire has good conductivity and is suitable for use in electronic components. For example, it can be used to manufacture electrodes in electronic components such as capacitors, inductors, and resistors

3. Processability: Tantalum wire can be processed at high temperatures and is easily combined with materials such as ceramics and glass, making it suitable for making other components of electronic devices

4.Low Thermal Expansion Coefficient: The wire maintains dimensional stability under temperature changes, ideal for precision applications.
