钨呈银白色，其熔点高达3400℃，是熔点最高的金属。密度为19.3克/厘米3。为钢的2.5倍与黄金相当。钨的导电性较好，其导电率高于镍、铁、磷青铜及铂。钨的膨胀系数较小。钨在常温下比较稳定，温度不高时，表面生成棕色和深蓝色氧化膜，在较高温度时，氧化激烈生成三氧化钨。

Tungsten is silver white, its melting point is as high as 3400, which is the highest melting point. Density was 19.3 g / cm 3. For steel 2.5 times as much as gold. The electric conductivity of tungsten is good, and its conductivity is higher than that of nickel, iron, phosphor bronze and platinum. The expansion coefficient of tungsten is small. Tungsten is stable at room temperature, temperature is not high, formed on the surface of brown and dark blue oxide film, in the high temperature, intense oxidation generated WO3.
