Molybdenum thread has unique qualities. She perseveres in aggressive environments, vacuum can withstand very high temperature up to 1800 °C, and compared with the tungsten filament, it is almost two times lighter, and therefore demonstrates a high specific strength up to 1370 °C has a high modulus of elasticity, and low coefficient of thermal expansion identical to glass, which allows the use of molybdenum filament for the input electrodes in vacuum devices. This thread is not as fragile as tungsten, is produced with less technological effort.
This thread has a high cost: molybdenum quite difficult to isolate in pure form, it is hard, refractory and difficult to process. However, the reliability and exceptional quality yarns made of molybdenum fully pay all costs.
First produced molybdenum wire Ø 1−10 mm, hot rolling the billet in a rotary forging machine. Then wire with lug pull in a very thin thread. It. can manufactured from pure molybdenum grades MCH and MCIT, and with the addition of cobalt or chromium. In this case, its adaptability and strength increase. From 1 gram of molybdenum is rolled into a filament with a length more than three meters.

Molybdenum filament used in the lighting devices. Depending on the diameter and surface condition to produce a spiral and respiratoorse cathodes, grids, springs, loop heaters electronic devices, springs of semiconductor devices. Also make entries, and traverse those parts of the device that do not require the use of doped tungsten.
