Rhenium is expensive, and the alloys containing rhenium are mostly used in applications, among which tungsten rhenium and molybdenum rhenium are the most widely used. Tungsten rhenium alloy contains 10%~26% Rhenium and molybdenum rhenium alloy contains 11%~50% Rhenium. In addition, there are W-33.3Mo-33.3Re, Mo-Re-Hf-Zr and Mo-Re-Hf -V alloys, the latter two alloys have high strength. Tungsten Rhenium and molybdenum Rhenium alloys have good high temperature strength and plasticity, and can be processed into plates, sheets, wires, wires and rods, which are used in aerospace and aerospace high temperature structural parts, elastic components, electronic components, etc. They can also be used in manufacturing heating elements, workpieces, light bulbs, X-ray instruments and medical instruments. W-Re-tho2 alloy can be used as high-temperature heating workpiece. Tungsten-rhenium and molybdenum-rhenium alloy contacts have high resistance to thermal corrosion and high-temperature conductivity, which can improve the service life and working reliability of power supply equipment. For example: platinum-rhenium alloy; Platinum-tungsten rhenium alloy; Tungsten rhenium alloy; Molybdenum rhenium alloy and so on.
Advantages: Compared with other rhenium content of rhenium tungsten wire, doped W-3Re alloy silk unique performance, high strength, good plasticity, with the highest of doped W-3Re recrystallization temperature of 2500 ℃, melting point is 3360 ℃, in the high temperature technology, electric vacuum industry, the light bulb, the original can industry and analysis technology, medical and chemical industry in areas such as widely used, is one of the rare, hard to replace the high temperature materials.
Disadvantages: Up to now, W-3Re alloy wire used in many fields in China still depends on import, such as picture tube electron gun, gas chromatograph thermal conductivity detector, electron tube in electric vacuum industry, tungsten rhenium wire for probe card used in electronic packaging test, etc.
