Product Characteristics

Tungsten Wire

 

Tungsten wire, made of thin wire after forging and drawing tungsten bars. Tungsten wire is mainly used in incandescent lamps, halogen tungsten lamps and other electric light sources. Tungsten wires used as various luminaries in light bulbs also need to be mixed with a small amount of potassium, silicon and aluminum oxides in the smelting process, which is called doped tungsten wire (Doped Tungsten Wire), also known as 218 tungsten wire or Non-sag TungstenWire.

The use of tungsten wire
1. Make the filament.
2. High speed cutting alloy steel.
3. Chemical instruments.
4. High temperature  wire for vacuum furnace.
5. Used as a filament for automotive halogen lamps.

Appearance of tungsten wire
1. The surface of tungsten wire is coated with graphite milk, and the surface is uniform black.
2. Tungsten wire after alkali washing, remove the surface graphite milk, metallic luster.
3. Tungsten wire is treated by vacuum hydrogen furnace, and the surface is bright.
4. Tungsten wire after electrochemical polishing treatment, the surface is bright.
