Filament is in the form of very thin coil wire or straight wire, which is used to convert electrical energy into light energy. This was the first optical power source, tungsten filaments were used in incandescent lamps or light bulbs.
Tungsten wire diamond wire, also known as tungsten wire rope, tungsten wire diamond cutting wire or tungsten-based diamond wire, is a kind of diamond wire with pure tungsten wire or doped tungsten wire as the busbar.
Producing tungsten wire is a complex and difficult process. The whole process must be strictly controlled by controlling the proper chemical composition to ensure the physical properties of the finished tungsten wire.
