Tantalum tubes have the following characteristics:
1. Excellent corrosion resistance:
• At room temperature, tantalum tubes do not react to hydrochloric acid, concentrated nitric acid and aqua regia, and also have strong resistance to many other corrosive media.For example, in the chemical industry, tantalum tubes can be used to transport a variety of corrosive liquids and gases.However, tantalum will be corroded in hot concentrated sulfuric acid, fuming sulfuric acid, high temperature phosphoric acid and hydrofluoric acid, but its corrosion resistance is still prominent below a certain temperature range.
2. High melting point and high boiling point: the melting point of tantalum is as high as 3017℃, and the boiling point is more than 5000℃.This enables tantalum tubes to maintain stable physical and chemical properties in high temperature environments, and can be used in high-temperature furnaces, aerospace engines and other fields that require high temperature resistance of materials.
3. Good coefficient of thermal expansion: The coefficient of thermal expansion of tantalum tubes is very small, and the size change is small when the temperature changes, which is very important for some application scenarios with high dimensional accuracy requirements, such as the manufacturing of electronic components and parts of precision instruments.
4. Good electrical conductivity: tantalum has high electrical conductivity, which makes tantalum tubes widely used in the electronics industry, such as for manufacturing capacitors, electrodes, rectifiers and other electronic components.
5. Good plasticity and ductility: tantalum has moderate hardness, good plasticity and ductility, can be drawn into fine wire or made into thin foil, and is also easy to process into various shapes of tantalum tubes to meet the needs of different application scenarios.
6. High strength and hardness: tantalum tubes have high strength and hardness, can withstand certain pressure and mechanical stress, and perform well in some occasions that need to withstand external forces.
7. Good biocompatibility: Tantalum has good biocompatibility, and in the medical field, tantalum tubes can be used to manufacture medical devices implanted in the human body, such as orthopedic implants, vascular stents, etc.
8. Good oxidation resistance: tantalum is not easy to be oxidized in the air, and a stable oxide film will be formed on the surface, which can protect the inside of the tantalum tube from further oxidation, improving the stability and service life of the tantalum tube.

Product Description

Tantalum tubes have many advantages such as corrosion resistance, good thermal stability and biocompatibility, and the following are its main application areas:

Chemical industry

• Tantalum tubes are widely used in the chemical industry. Due to its excellent corrosion resistance to strong acids (such as hydrochloric acid, sulfuric acid, nitric acid) and strong alkali, tantalum tubes are used to make various chemical reaction vessels, heat exchanger pipelines, and pipeline linings, etc., to ensure the safe transportation of corrosive fluids in chemical production.

Electronics industry

• Tantalum capacitors are one of the important applications of tantalum.Tantalum tube can be used as the shell of tantalum capacitor, used to manufacture high-performance, high-stability capacitors, widely used in computer motherboards, mobile phones, digital cameras and other electronic equipment, can effectively filter the clutter in the circuit, stable current.

Medical field

• Tantalum has good biocompatibility, and in the medical field, tantalum tubes can be used to make medical devices implanted in the human body, such as prosthetic joint joint components, vascular stents, etc., to help patients restore physical functions.

Aerospace field

• Aerospace equipment needs to withstand extreme environments, tantalum tubes can be used for some high-temperature and corrosion resistant parts of aircraft engines, or as a part of the fuel delivery pipeline of aerospace vehicles to ensure the stable operation of aircraft in harsh environments.
