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 aircraft and space technology

Molybdenum and its alloys are used in the form of plates, volumetric profiles, wires, pipes and foils, obtained by powder metallurgy and further deforming treatment. Pressing is carried out using linear and isostatic presses. Pressed compacts are sintered in a hydrogen atmosphere at temperatures of 2000−2200 ° C, resulting in increased strength and density of materials.

The high melting point and high high-temperature strength of molybdenum allow it to be used at temperatures up to 1900 ° C, typical for aviation and rocket engines, high-temperature fasteners, outer skin of fuselages and bodies of space and aviation equipment. In aviation and cosmonautics molybdenum is used due to its exceptional mechanical stability at high temperatures.

Supplier — AvekGlob Company — offers to purchase a wide range of brands of different types of molybdenum profiles used in aviation and cosmonautics. 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.
