1) Strong corrosiveness;
2) High temperature resistance
3) Long service life
WB001 has good winding performance, no sagging, suitable for ordinary incandescent lamps, double helix or triple helix fluorescent lamps, holiday lights, bracket wires, etc.
WB150 has good high temperature resistance and excellent processing performance, and is suitable for halogen lamps, spiral incandescent lamps, etc.
WB584 has high recrystallization temperature and good high temperature and sagging resistance, which is suitable for special lamps such as seismic filament and high color temperature filament.
Use:
1. Manufacture of electric light source and electric vacuum parts;
2. Used as high-temperature heating element and high-temperature structural parts;
3. Used to make tungsten spiral for vacuum evaporation;
Appearance: The surface of tungsten wire is coated with graphite emulsion, which is relatively uniform black, and the graphite emulsion is removed to show a metallic luster.
