Properties of Tantalum

Tantalum has a series of outstanding properties, such as high melting point, low vapor pressure, good cold processing performance, high chemical stability, strong resistance to liquid metal corrosion, and large surface oxidation film dielectric constant.
Therefore, Tantalum is widely used in many fields including electronic metallurgy, steel industry, cemented carbide nuclear superconductivity technology, automobile, electronics, aerospace, medical and health, scientific research and other high-tech fields.
