Tantalum Tungsten Alloy Ta2.5W Tube

97.5% Tantalum 2.5% Tungsten (Ta-2.5W) alloy is widely used in the chemical industry. The corrosion resistance of tantalum-tungsten alloy is better than that of pure tantalum.Ta2.5W can be used as anti-corrosion parts for heat exchange equipment, pipelines and linings in chemical industry, anti-corrosion of instruments and meters, and crucibles for rare earth smelting.

Ta2.5W alloy steel pipe is mainly used for making vacuum blast furnace with heat generating parts, heat insulation parts and charging vessels; used in chemical anticorrosion industry, the production of composite plate manufacturing anticorrosive containers, reaction kettles, distillation towers, corrosion of ships.

Because the strength of tantalum-tungsten alloy is higher than pure tantalum, and the corrosion resistance is similar to pure tantalum, it has been used in the chemical industry and aerospace industry, thus it has been used in the chemical industry and aerospace industry.Ta-2.5W alloy is mainly used in the manufacture of heaters, cooling coils, heat exchangers, and reactors, etc. Ta-7.5W alloy is mainly used as the spring material in the chemically corrosive equipments and other corrosion-resistant elastic components. Due to the high potential of tantalum and tantalum alloys, they become cathodes when they are in contact with other metals and easily absorb atomic hydrogen to make metal tantalum and tantalum alloys brittle. Therefore, when used in the manufacture of chemical equipment, it must be prevented from becoming a cathode.Ta-10W alloy can be used as a gas temperature of 3300 ℃ above the liquid rocket engine thrust combustion chamber, high-temperature vacuum furnace heaters and other high-temperature parts.
