High ductility, toughness and strength of molybdenum allow laminating a sheet of any format. The addition of cobalt increases the ductility of the sheet in the annealed condition. Molybdenum sheet is small in coefficient of thermal expansion, high elastic modulus, excellent chemical resistance, allowing it to be used, including in aggressive environment. The melting point of molybdenum 2620 °C refractoriness, it is second only to tungsten, rhenium, osmium, iridiu. Molybdenum sheet retains adequate strength at temperatures of 2000 °C. To 1370 °with its relative thermal strength is higher than that of tungsten. High performance: heat resistance, corrosion resistance, mechanical strength, molybdenum sheet allow you to work effectively in the toughest industrial conditions. In addition, such a sheet of biologically inert and absolutely safe to human body, meets all sanitary requirements
The disadvantage is the high production cost of molybdenum sheet. Due to the considerable refractoriness molybdenum difficult technological processing. Production it time-consuming, and obtaining it in its pure form is quite difficult. In normal circumstances, this is not enough technological material.
Normalized GOST 17431−72. Molybdenum sheet produced in the following grades: MCH and M. cold-Rolled sheet is rolled, thickness 0.1 — 0.9 mm, hot-rolled — thickness 1 — 30 mm. surface of the sheet must not contain traces of oxidation, grease, etc. contamination. The surface should be smooth, without cracks, burrs or other defects.

Molybdenum sheet is in the manufacture of heat-resistant fencing, in heat-resistant containers, boats, etc. With a thin sheet and ribbon used in the manufacture of heating elements heat the ovens, as well as input electrodes in devices that are operated in a hydrogen atmosphere, at temperatures up to 1600 °C. Molybdenum plate is used in x-ray tubes, and electronics.
