Tungsten filamentHengmi uses stable quality tungsten and molybdenum raw materials to customize and process tungsten filament, tungsten coil, tungsten heater, tungsten stranded wire, electron gun filament, ion source filament, EB filament, etc. for vacuum heating field. Its creep resistance, durability, thermal conductivity, reliability and mechanical stability can meet the customer's customized requirements.
Advantages of hengmi tungsten filament：
1.It has excellent high temperature bearing capacity, anti sagging, corrosion resistance and other properties.
2.Special materials for vacuum coating, tungsten and molybdenum materials with purity greater than 99.95%, can prevent the pollution of evaporation materials and substrates; special rare earth or potassium elements are added to further optimize the performance of high temperature, creep resistance and corrosion resistance, and the recrystallization temperature is increased, which can ensure that the filament is not easy to deform in the working process and meet the customer's customized requirements.
3.Our tungsten materials are highly densified, with relatively high density, uniform internal structure, constant resistance, stable heat resistance, etc., and obviously better service life.
4.We have more than 10 years of tungsten and molybdenum products processing experience, accurate filament size control. Customized tungsten filaments of various shapes and precision, and provide different grades of tungsten materials. The filaments are made of pure tungsten (99.95-99.98%), doped tungsten (99.95%), rare earth tungsten and other raw materials, or customized materials according to customer requirements.
