Tantalum metal (Ta) is a slightly blue-light gray metal, due to its many exotic properties, has a wide range of applications, and, therefore, is known as the "metal kingdom" of generalists. Tantalum is used in electronics, medical devices, aerospace components, and chemical processing equipment due to its excellent electrical conductivity, corrosion resistance, and biocompatibility.
HSG Metal is a leading manufacturer and supplier of tantalum products in China. We provide a wide range of tantalum products including tantalum powder, tantalum wire, tantalum rod, tantalum sheet metal, and tantalum tube at affordable prices. Different grade options for tantalum products. Custom sizes are availale. Check out the details of our tantalum metal products. Contact us if you have any needs or questions.
Atomic Number: 73
Symbol: Ta
Melting Point: Approximately 3,017°C (5,463°F), making it one of the highest-melting metals.
Density: About 16.69 g/cm³
Electrical Conductivity: Excellent conductor of electricity, with low resistivity.
Corrosion Resistance: Highly resistant to chemical attack, especially by acids, making it suitable for harsh environments.
Tantalum has excellent plasticity, making it well-suited for plastic processing. Using conventional methods such as extrusion, forging, rolling, and stretching, it can be shaped into various industrial profiles, including Tantalum tubes, Tantalum rods, Tantalum wires, and Tantalum tapes.
Tantalum and tantalum alloy ingots initially have a coarse grain structure, which must be refined by extrusion or hot forging to enable further processing. During processing, pure tantalum can penetrate alloy substrates, forming a hard permeable zone that may crack. Therefore, it is essential to protect the metal surface from oxidation throughout the process. Currently, common protective methods for tantalum billets include salt bath heating, coatings, and gas shielding.
Pure tantalum can undergo forging at room temperature, whereas tantalum alloys require high temperatures (100–1200°C) to avoid surface oxidation and the formation of porous oxides. Tantalum can also be made into welded and seamless tubes, which are used across a broad range of applications.
The process of reducing pure tantalum compounds to metallic tantalum with a reducing agent. The raw materials of pure tantalum compounds used are tantalum pentoxide, tantalum pentachloride, tantalum pentafluoride and fluoride salts (such as K2TaF7). Reductants include sodium, magnesium and other active metals, carbon and hydrogen. The melting point of tantalum is as high as 3669K, so it is powdered or cavernosum metal after reduction. The dense metal can only be obtained by further smelting or refining.
Tantalum is one of the most chemically stable metals at temperatures below 150 ° C. Only fluorine, hydrofluoric acid, acidic solutions containing fluoride ions and sulfur trioxide can react with tantalum.
Tantalum is very hard, with a hardness of 6-6.5. Its melting point is as high as 2996℃, third only to tungsten and rhenium.
Tantalum is malleable and can be drawn into filaments or made into thin foil.
Its coefficient of thermal expansion is small, at 6.6 parts per million per degree Celsius
In addition, it is very strong, even better than copper.
