乌克兰材料研究所研制成一种新型的钨钼合金 ,该合金具有很高的耐磨性和耐电弧性 ,特别适用于制作导电触头和熔化焊条。用这种合金制造的导电触头 ,其使用寿命要比青铜、黄铜等铜制触头延长5～ 10倍 ;用它制造的电焊条 ,不仅可以提高焊接质量 ,而且可以降低焊条的消耗。这种合 Ukraine Institute of Materials developed a new type of tungsten and molybdenum alloy, the alloy has high wear resistance and arc resistance, especially for the manufacture of conductive contacts and melting electrodes. Conductive contacts made of this alloy have a service life that is 5 to 10 times longer than copper contacts such as bronze, brass, etc .; welding electrodes made of it can not only improve the welding quality but also reduce the consumption of welding electrodes. This combination
