Molybdenum wire

Molybdenic wire possess low coefficient of temperature expansion, high rates of elasticity and hardness, viscosity and firmness in hostile gas and liquid environment. It has the high mechanical durability, corrosion firmness, reliability that allows to use it in many branches of a national economy. One of the defining shortcomings of such wire, the high cost of production is. Mo - rather rare metal, differs in complexity of smelting, badly gives in to processing, refractory. In pure form it is heavier than steel and iron and is fragile metal though gives to alloys durability. At usual temperatures it differs in low plasticity

According to requirements of TU, the surface of a molybdenic wire should not have traces of greasing, oxidation and other types of pollution. A wire from molybdenum to 0,4mm - dark gray or black. Thicker wire light gray. The surface of a wire has to be rather smooth, without agnails, cracks, etc. similar defects. On a wire more 0,5mm agnails if they do not exceed tolerances by the size can be diameter. Norms are specified a gap and stretching in special tables. The high-quality wire from Mo has to maintain spiralling.

Molybdenum is known for the exclusive properties as the heat resisting and heat-resistant material capable to resist to corrosion, refractory. Provolok from this metal widely apply in easy and heavy mechanical engineering. Such wire, as well as tungsten, is used in illuminants, for tools with high thermal stability, corrosion firmness and high durability. Distinguish a molybdenic wire of several brands, excellent on the content of impurity and a way of production. The wire of the MCh brands is most popular
