The range of molybdenum is able to withstand high mechanical loads even at high temperature. It is characterized by heat resistance, heat and corrosion resistance, resistant in solutions of concentrated acids and alkalis, has a high modulus of elasticity, low coefficient of thermal expansion, viscosity, hardness. These advantages allow to apply it in various fields of modern industry. It has wonderful mechanical strength compared to tungsten — it is half the size, and therefore has a large specific strength (at t° to 1370°C).

A circle of titanium-molybdenum alloys easily transfers heat to t° 1500 °C. Molybdenum circle MCH, MC, MS (doped with silicon) is operated at temperatures above 2000 °C. the Circle marks MPH, MCH, and molybdenum with silicon-base additive, have high tensile strength and Flexural strength in the annealed condition, and the recrystallization temperature. Doping an impurity of cobalt increases ductility in the annealed condition.
