Tantalum Rod and Tantalum Bar

Tantalum Rod is made from high-purity tantalum metal, known for its excellent corrosion resistance, high melting point (around 3000℃), and outstanding oxidation resistance. It is commonly used to produce high-performance capacitors, transistors, chemical reactors, and high-temperature components.
