Molybdenum and molybdenum alloy, molybdenum machined parts are widely used in manufacturing the core wire, lead wire, hook, bracket, sidebar and other parts of the spiral the filament in the bulb.

Molybdenum has good conductivity and high-temperature properties, especially, it's thermal expansion coefficient is very similar to that of glass. Molybdenum and molybdenum alloy, molybdenum machined parts are widely used in manufacturing the core wire, lead wire, hook, bracket, sidebar and other parts of the spiral the filament in the bulb, and can also be used as the grid and anode supporting material in the tube. The "bimetallic effect" can be eliminated by placing the integrated circuit (IC) on molybdenum, which is used as the MOS gate in Very Large Scale Integration (VLSI).

Molybdenum tube

Ultra-thin seamless molybdenum tube (about 15μm) can be used as anode support for high definition TV picture tube. The TV has an image scan of 1,125 lines, which is twice as fast as a typical TV. Molybdenum foil can also be used as a power transistor insulation screen and silicon rectifier substrate and heat sink.

Molybdenum alloy

In addition to pure molybdenum, Mo-Re alloys can be used as structural materials for electron tubes and special light bulbs, and Mo-50Re and TZM alloys can also be used as thermionic cathode structural elements in high power microwave tubes and millimeter wave tubes. Its operating temperature can reach 1200, and the current density can reach 10 amperes/cm 2.

Molybdenum wire

The recrystallization temperature of pure molybdenum wire as the lead wire is low, and it is easy to be embrittlement at high temperature, which affects the service life. In recent years, Si, k, C and other elements were added to improve the recrystallization temperature and produce "high temperature molybdenum wire".

The addition of rare earth elements yttrium, cerium and lanthanum in the production process of molybdenum oxide can effectively improve the recrystallization temperature and overcome the problem of brittleness at high temperature. Molybdenum wire containing 0.1-0.3% zirconium and 0.1% scandium is nitrized at 1200 to disperse scandium into the whole alloy. The tensile strength of molybdenum wire can reach 1400 million pascals at 20.

With the rapid development of die industry, electric discharge machining (EDM) technology is widely used. Molybdenum wire is an ideal electrode wire for EDM machine tool, which can cut various kinds of steel and hard alloy, and process extremely complicated parts. Its steady discharge machining can effectively improve the precision of the mold.

Molybdenum-copper material

Tungsten-copper alloy has been widely used as an electrode for EDM tools, and molybdenum has been used as an electrode instead of tungsten in recent years. The results show that the corrosion resistance of tungsten and molybdenum based electrodes varies with the content of copper (50% by weight). When heating pulse and mechanical load pulse exist, the corrosion resistance mainly depends on the brittle process. The duct-brittle transition temperature of molybdenum is lower than that of tungsten, so the brittleness is small and the corrosion resistance is strong.

Molybdenum-copper, the molybdenum-silver alloy has good ablative resistance and electrical conductivity, and can be used as the contact of air switch, high voltage switch and contactor. The molybdenum-copper composite film contains a large number of discrete molybdenum particles on the continuous copper body, with uniform microstructure, good conductivity, and conductivity through-thickness, and can be used as metalcore in multilayer circuit boards.

Molybdenum trioxide

Recently, molybdenum trioxide, a discoloration material that changes color when exposed to strong light and can be easily reduced, has been developed for use in electronic computer optical storage components and reproduces materials used many times.
