钨铼合金丝是在不下垂钨丝成份的基础上加入铼成份。铼的加入,多方面改善了钨丝的性能,它还可以弥补普通用钾—硅—铝掺杂的不下垂钨丝的不足,制成长寿命、高可靠阴极加热灯丝,改善使用性能。 钨铼合金丝的优良性能表现在:
Tungsten rhenium alloy wire is not sag tungsten wire composition based on the rhenium ingredients. The addition of rhenium can improve the performance of the tungsten wire in various aspects. It can also make up for the shortage of conventional tungsten-silicon-aluminum-doped non-sagging tungsten wire and make the long-life and highly reliable cathode heating filament to improve the serviceability. Tungsten rhenium alloy wire excellent performance in:
