Product Description
Purity 99.95% Pure Tungsten Filament
1. Description of Purity 99.95% Pure Tungsten Filament:
A tungsten bar is forged and drawn to create tungsten filament.
Electric light sources like incandescent lamps and tungsten halogen lamps are the principal uses for tungsten filaments.
The tungsten wire used for various luminous bodies in bulbs also needs to be doped with a small amount of potassium, silicon and aluminum oxides during the smelting process. This tungsten wire is called Doped Tungsten Wire, also known as Doped Tungsten Wire. Tungsten wire 218 or tungsten wire that doesn't sag (Non-sagTungstenWire).
Various drawing dies are typically used to draw tungsten wire. The production of filament and high-speed cutting alloy steel is the primary objective. These materials are also used to make optical and chemical instruments, among other things.
