Tantalum 10 Tungsten Rod

Tantalum 10 tungsten rod, as a high-performance tantalum tungsten alloy material, has shown wide application potential in multiple industrial fields due to its unique physical and chemical properties. The Ta-10W alloy rod is mainly composed of two metal elements, tantalum (Ta) and tungsten (W), with tantalum content typically ranging from 88-92% and tungsten content ranging from 8-12%. This alloy not only inherits the high melting point, high corrosion resistance, and good ductility of tantalum, but also combines the high strength and hardness characteristics of tungsten, allowing Ta-10W alloy rods to maintain excellent performance in extreme environments.

In addition, Ta-10W alloy rods may also contain trace amounts of other elements such as carbon (C), nitrogen (N), oxygen (O), iron (Fe), chromium (Cr), etc. The content of these elements is usually controlled below 0.1% to ensure the purity and stability of the alloy. The high density (≥ 16.6g/cm ³) of this alloy is also one of its significant characteristics, making it excellent in various heavy-duty and high-temperature applications.

The production process of Ta-10W alloy rod is complex and refined, mainly including several steps such as powder mixing, compression molding, sintering, melting, forging, and annealing. Firstly, mix the ultrafine tantalum powder and tungsten powder evenly according to the required ratio to ensure the accuracy of the alloy composition. Then, the mixed powder is loaded into a mold and a preliminary alloy billet is obtained through compression molding. Place the alloy billet into a vacuum sintering furnace and perform high-temperature sintering to form metallurgical bonds between the powder particles, resulting in coarse ingots. Then, the coarse ingot is melted multiple times in a vacuum electron beam furnace or vacuum arc furnace to further purify and homogenize the alloy composition, resulting in an alloy ingot. Finally, the alloy ingot is subjected to multiple forging and vacuum annealing treatments to improve its mechanical properties and microstructure. Finally, Ta-10W alloy rods with excellent performance were obtained through machining and polishing processes.

Ta-10W alloy rod has a series of excellent performance indicators. Tantalum is a rare metal with a high melting point and high corrosion resistance, possessing excellent ductility and processability; Tungsten is one of the hardest metals in nature, with extremely high strength and hardness. The combination of these two metals enables Ta-10W alloy rods to exhibit excellent performance in extreme environments, such as high temperature stability, corrosion resistance, high strength, and good mechanical properties. At room temperature, the alloy has high strength and ductility. As the temperature increases, although the ultimate tensile strength decreases rapidly, the rate of decrease in yield strength and elastic modulus is relatively slow. At the same time, the elongation and cross-sectional shrinkage of the alloy will increase, especially exhibiting high plastic deformation ability at high temperatures.

These excellent properties make tantalum 10 tungsten rods widely used in multiple industrial fields, including but not limited to corrosion resistance and superconductivity, chemical industry, high-temperature technology, and atomic energy industry. In the corrosion-resistant and superconducting industries, it can be used as key components such as tantalum capacitors and tantalum electrodes; In the chemical industry, it can be used to manufacture equipment such as steamers, heaters, coolers, etc; In the field of high-temperature technology, it can be used to manufacture high-temperature components such as high-temperature furnace parts; In the atomic energy industry, it is an important material for key components such as nuclear fuel cladding.
