Best Tube Ray Cathode

Oiyagai 10 Pcs Common Cathode 10-Pin 1 Bit 7 Segment 0.56\ Red LED Display Digital Tube

Purity: W ≥ 99% . Dimensions: diameter:0.04-0.1mm(Buy on demand) , length:1m. Package: 1 x Tungsten wire.
Tungsten and its alloys are widely used in electronics and power industry because of its strong plasticity, low evaporation rate, high melting point and strong electron emission ability. For example, due to its high luminous efficiency and long service life, tungsten filament is widely used in the manufacture of various bulb filaments, such as incandescent lamp, iodine tungsten lamp, etc,.
Tungsten wire is used to make direct hot cathode and grid of electronic oscillator tube and side hot cathode heater in various electronic instruments. The properties of tungsten make it suitable for TIG welding and other electrode materials similar to this kind of work..
It is widely used in aerospace, aviation, oil drilling, electrical instrument and other industries, such as manufacturing heat sink, balance weight of control rudder and contact materials of switch, circuit breaker, spot welding electrode, etc..
