FW & HW two series tungsten wires both are doped with Potassium (K), Silicon (Si), Aluminum (Al), which have a good reputation with customers both domestic and overseas.

FW series wire is our standard non-sag, high quality, and characterized by long grain recrystallized, especially good for high speed coiling. As the raw materials, FW wire is often used to be filaments for fluorescent lamp. 

HW series wire excels in high temperature vibration resistance and anti-blackening property. It varies from a standard non-sagging wire, which is developed especially for halogen lamp filament by our original production control.

We produce these wires via a technology well established by our experience and knowledge of customers needs. We also undertake consignment processing on customer's request, such as heavy tungsten wire for redraw.
