Advantages and disadvantages of Tungsten rhenium alloy

Advantages：Compared with other rhenium content of rhenium tungsten wire, doped W–3Re alloy wire 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.
