Pure Tantalum Bar

Product Introduction

The Pure Tantalum Bar is a premium-grade refractory metal product characterized by excellent corrosion resistance, high melting point, and outstanding ductility. It is manufactured using high-purity tantalum (≥99.95%) and advanced processing techniques, ensuring uniform composition and fine-grained structure. Pure tantalum bars exhibit exceptional chemical stability in acidic and high-temperature environments, making them ideal for use in the chemical, electronic, aerospace, and medical industries. Shaanxi Chuanghui Daye Metal Material Co., Ltd. provides Pure Tantalum Bars in various sizes and specifications according to ASTM B365 and other international standards. They are widely used in manufacturing furnace components, electrolytic capacitors, evaporation boats, and precision machining parts that require superior corrosion and heat resistance.

Chdymetal can offer pure tantalum bar with various purities and sizes. Tantalum bar have unique properties such as high melting point, corrosion resistance, and biocompatibility, making them the preferred material in medical, mechanical parts, aerospace, and laboratory equipment industries. Tantalum bar can be shaped in a tantalum round bar and tantalum square bar.

More details information as below:

Tantalum metal is stable in air at room temperature, when heated above 500 ° C, oxidation is accelerated to produce Ta205. Tantalum has a series of excellent properties such as high melting point, low steam pressure, good cold working performance, high chemical stability, strong resistance to liquid metal corrosion, and large dielectric constant of surface oxide film, and has important applications in high-tech fields such as electronics, metallurgy, steel, chemical industry, cemented carbide, atomic energy, superconducting technology, automotive electronics, aerospace, medical health and scientific research.
