Rare refractory metals and alloys

Tungsten is a metal to which special weight, hardness and refractoriness are characteristic. Tungsten a basis of firm alloys and many heat resisting alloys, is a part of durable alloys and tool staly. Characteristics of metal Tungsten: • temperature of melting makes 3380 °C• temperature of boiling...
