Properties of molybdenum

Molybdenum is a refractory metal, usually used at high temperatures. Its operational properties include:

• Low coefficient of thermal expansion (5.1x10−6 m / m / ° C), which is about half that of most steels;

• Good thermal conductivity;

• Good electrical conductivity;

• Good stiffness, which is higher than that for steel (molybdenum modulus is 317 GPa);

• High melting point (2615 ° C);

• Good strength;

• Good strength and ductility at room temperature;

• High density (10,200 kg / m ³).

The ability of a given metal to withstand high temperatures and maintain strength under these conditions is the reason that molybdenum finds the predominant part of its applications at elevated temperatures. In fact, it can operate at temperatures above 1100 ° C (in non-oxidizing media), which is higher than the steel and most nickel-based alloys.

If the temperature rises above 760 ° C in air, rapid oxidation can occur. Under these conditions, the oxide layer and the base metal begin to form on the surface of the metal. Thus, molybdenum works best in an inert environment.

Supplier — AvekGlob Company — offers molybdenum in a wide range of brands and profiles, and at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Application in electronics and electrical engineering

Molybdenum and its alloy are used to make:

Pins, hooks and supports for tungsten filaments in traditional incandescent lamps, mandrels for the production of single and double coils of tungsten wire, shields for dimming car headlights;

Pins for vacuum-sealed connections, gold-plated nets for improving the emission of electrons, anode tubes, auxiliary electrodes, cathode supports and other structural elements for emitter tubes, short-wave tetrodes, high-power tetrodes, microwave magnetrons, etc .;

Details of transistors and semiconductor elements, in particular, cathode contacts, special contacts, as well as contacts in mercury switches and telephone relays;

Lamp electrodes for creating an arc in gas-discharge lamps, as a wire for halogen lamps, pipes for annealing fiber wires, evaporative boats for coating cold-light reflectors;

Semiconductor support plates, pipe components, such as crucible grids, rings and anode and cathode holders, radiators of passive cooling devices, boats and cups for sintering capacitors.

Supplier — AvekGlob Company — offers to purchase a wide range of brands of various types of molybdenum profiles used in electrical engineering and electronics. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
