1. 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. For a variety of light bulb for the tungsten wire, also need to mix a small amount of potassium, silicon and aluminum oxides. Nowadays, the tungsten wire is generally made of a variety of drawing dies. The main application is to create the filament and high-speed cutting steel, also used in optical instruments, chemical apparatus and so on.

2,Tungsten Wire Product Feature

Doped tungsten wire are manufactured by the high tech of doping, acid washing, isostatic pressing, PLC controlled direct-sintering, swaging and auto feeding, The products are featured with minimum deformation at high temperatures, high recrystallization temperatures, uniformity in dimension and excellent coilability. For tungsten rod weighing 3kg.pc, its rough welding tungsten wire weighing 5kg/pc, this technology lakes lead in China, Customers are allowed to choose various types of tungsten wire in accordance with their specific applications.
