Molybdenum alloy is a non-ferrous alloy composed of molybdenum as the matrix and other elements added. The main alloying elements are titanium, zirconium, hafnium, tungsten and rare earth elements. Titanium, zirconium and hafnium elements not only play a solid solution strengthening effect on molybdenum alloys and maintain the low-temperature plasticity of the alloys, but also form stable and dispersed carbide phases to improve the strength and recrystallization temperature of the alloys. Molybdenum alloy has good thermal conductivity, electrical conductivity and low expansion coefficient, high strength at high temperature (1100 ~ 1650 ℃), easier to process than tungsten. It can be used as the grid and anode of electron tubes, the support material of electric light source, as well as for making die-casting and extrusion molds, parts of spacecraft, etc. Because molybdenum alloy has low temperature brittleness and welding brittleness, and it is easy to oxidize at high temperature, its development is limited. Industrially produced molybdenum alloys include molybdenum titanium zirconium series, molybdenum tungsten series and molybdenum rare earth alloys, which are widely used. The main strengthening methods of molybdenum alloys are solid solution strengthening, precipitation strengthening and work hardening. Through plastic processing, molybdenum alloy sheets, strips, foils, pipes, bars, wires and profiles can be obtained, and their strength and low temperature plasticity can also be improved.
Molybdenum alloy plate (stamping tool)
An alloy based on molybdenum with other elements added. Among the refractory metals, molybdenum and its alloys have good thermal conductivity, electrical conductivity and low expansion coefficient (similar to the glass used in electronic tubes), and have high strength at high temperature (1100 ~ 1650 ℃), compared with tungsten, Easy to process, it is used in the manufacturing sector of electronic tubes (grids and anodes), electric light sources (support material), metalworking tools (die-casting and extrusion dies and perforated plugs), and the aerospace industry. Molybdenum is resistant to corrosion by molten glass, and its oxides do not contaminate the glass. Molybdenum has been used in the glass industry as heating electrodes since 1943. Mo-30W alloy has excellent corrosion resistance to molten zinc and has been successfully used in zinc smelting industry. Molybdenum is also used to make components such as heat exchangers and valves in sulfuric acid production.
