Tantalum tungsten alloy

Tantalum has strong resistance to chemical and atmospheric erosion below 150℃. Except for hydrofluoric acid, fuming sulfur trioxide and concentrated sulfuric and phosphoric acid at high temperature, all other acids are the most stable in pairs.

The reliability of Ta-W alloy is even higher than that of gold and foil in acidic and neutral medium at 200℃. Placer reserves: Tantalite minerals are mainly distributed in Guangdong, fine SPAR minerals in Hunan and Guangdong, the former 55.5%, the latter 44.4% superconducting material industry, some niobium compounds and alloys have high superconducting transition temperature, so it is widely used in the manufacture of various industrial superconductors. Superconducting generators, such as the accelerator high-powered magnets, superconducting magnetic energy storage device, such as nuclear magnetic resonance (NMR) imaging equipment carbide grain size is the same as the components (or phase) in microns, use a metal binder together tantalum carbide grain besides is a particularly special erosion resistance, and good hardness, plasticity, thermal conductivity and processing performance, So chemical equipment more valuable structural material. Tantalum products are widely used in chemical processing industry, petroleum industry, pharmaceutical manufacturing industry and food processing industry.

Tantalum can be used to make various malleable alloys with high melting points. Those alloys can be used to make superhard metals and superalloys for use in jet engines and chemical testing equipment.

Tantalum is most commonly used in surgical devices and implants because it is resistant to biological fluids. For example, tantalum can indirectly bond hard tissue, so many bone implants are porous tantalum coatings.

The use of tantalum ① in the collection of all kinds of inorganic acid in the assembly, tantalum can be used as a substitute for stainless steel, the number of years is dozens of times higher than stainless steel. (2) In chemical industry, electronics, electrical and other industries, tantalum can replace the responsibilities carried by precious metal platinum in the past, so that the cost is greatly reduced. ③ Half of the world's production of tantalum is used in the production of tantalum capacitors, which can be installed in military assembly.

Synthesis reaction in chemical medium tantalum tungsten alloy has good quality, tantalum can form a surface oxide film quickly and wrap it on the metal matrix carefully in other environment basically, the oxide film is thin and dense, is impervious to basically all the media, and can immediately recover if it is damaged.

Because of an excellent protective film like this one, tantalum is more resistant to corrosion. Tantalum is impervious to erosion in most media except fluorine, hydrofluoric acid, acidic sols containing fluorine ions, fuming nitric acid, and strong bases. The table below shows the corrosion resistance of tantalum compared with titanium and zirconium.

Performance tantalum tube can produce welded tube and seamless tube, has a wide range of uses. Seamless tubes are made by extrusion, tube reduction, or sheet deep drawing. The method of welding is to produce the strip first, then make the tube shape, The joints are then welded using gas tungsten arc (GTAW) Strong corrosion resistance, high temperature resistant pressure high, use fixed number of year is very long, low professional good safety crisis: domestic patent technology patent, used in various fields of erosion environment and gain access to all kinds of anti-corrosion, supply timeliness fast, cost-effective, cost far less than the pure tantalum, obtain working condition requirements, higher value-added items, goods price.

Tantalum tungsten alloy is of excellent quality. Tantalum is a kind of non-ferrous metal which is steel grey. Because it has many peculiar characteristics, it is also said to be a "noble metal" and because of its widespread application, it is called a generalist of "metal kingdom". Tantalum is a contemporary functional material worthy of attention because of its good mechanical properties, stable chemical properties and high dielectric constant of oxide film.
