1. High melting points and high corrosion resistance
2. Super thermal efficiency
3. Long life

Tungsten wires are made of selected high-quality material of tungsten, with the properties of excellent thermal conductivity, finely processed, and long duration.
Unusual stranded tungsten wires are applied as evaporator (heating element) in the vacuum metallizing (evaporation) process to coat thin film on surface of mirrors, kinescope, toys, home appliance, machine and various decoration, etc.
