Pure Tungsten Filament
Pure Tungsten Filament Description
Material selection and processing
Our company uses high-quality and high-purity tungsten powder through pressing, high-temperature sintering, wire drawing, heat treatment, surface coating treatment and performance testing. Tungsten's high melting point and high tensile strength are very suitable for the production of heating wires of various shapes.
Characteristics
- High strength, high hardness, high melting point, good processing performance
- Low vapor pressure, good dimensional stability, strong deformation resistance
- Excellent thermal and electrical conductivity, large resistance, easy to maintain high temperature form
- Corrosion resistance, oxidation resistance, long service life
Application
Pure Tungsten Filament is mainly used as filament material for conventional lamps such as incandescent lamps, halogen lamps or fluorescent lighting. It can also be used as heating wire in electron tubes, lighting systems in semiconductor engineering, microscopes in scientific research, medical equipment or jewelry manufacturing.
