Brief Introduction of?Tungsten Wire?There is a kind of?tungsten?wire named Doped Tungsten Wire, also known as 218 tungsten wire or non-sag tungsten wire. It is the forging of?tungsten bar, and made of fine wire drawing, mainly used in incandescent, halogen and other electric light sources.
Heating Resistors are used as heating components to plate the substrates of kinescope,mirrors,plastics,metal and various decorations.Stranded wires are used as raw material of heating elements,and also as heating components of semiconductors and vacuum devices directly.
The surface of electrolytic polished tungsten wire shall be smooth, clean gray silver with metal luster, Thetungsten wire features excellent formability, long life and super lighting efficiency , Mainly applied for making various electron tube, H series auto lamp, balogen lamp and other special lamp.
