Tantalum Tungsten (Ta10W) Alloy Products Description
90% Tantalum 10% Tungsten (Ta-10W) alloy is perfect for high pressure, high temperature and anti-corrosion. It is widely used in chemical, aerospace, atomic industry and high temperature components. Ta-10W alloy can be used in liquid rocket engine thrust chambers whose gas temperature is above 3300 ˚C, high temperature parts of high temperature vacuum furnace heating element. Ta-10W can also be used as fasteners in chemical industrial corrosion protection.
Ta-10W alloy has high high temperature strength, good ductility, weldability and excellent corrosion resistance, suitable for high temperature, high pressure, corrosion resistance and other working environment, widely used in chemical industry, aerospace, atomic energy industry and high temperature technology, is a very important engineering, functional materials.
Ta10W alloy is an important member of the Ta-W alloy family. Its corrosion resistance is similar to that of tantalum, and its stability is good in acidic and neutral media. Compared with other materials, it can withstand the corrosion of high temperature and mineral acids (hydrochloric acid, nitric acid and sulfuric acid). At the same time, it has excellent thermal conductivity, the thermal conductivity is more than twice that of titanium, more than three times that of zirconium and stainless steel, and four times that of nickel-based alloy. It is an ideal material for manufacturing chemical reaction vessels, heat exchangers, and heat transfer components such as condenser, beaker heater, spiral coil, U-pipe, sprayer and reboiler, etc.
The density of Ta10W alloy is 16.78~16.90g /cm3, the melting point is up to 3080℃, has very good mechanical properties at room temperature and high temperature, at 2000℃, the tensile strength of Ta10W alloy can reach 100MPa, and has very good welding properties. The high temperature strength of Ta10W alloy is high, but the elongation rate is not more than 50%, high temperature creep resistance is good, high temperature durability is also very good, excellent properties make Ta10W alloy has a very important application in the field of aerospace.
Processing technology of Tantalum 10 Tungsten(Ta-10W)
The key of Ta-10W processing is the cogging. It can be used in a set of forging extrusion and package or use canned extruding into bar (glass powder lubrication), and then made the slab by heating (choose high temperature anti-oxidation coating protection), remove the defects and machined surface oxidation layer, and then warm rolling, pickling, vacuum annealing, cold-rolled, vacuum annealing.
