Tungsten heater wire
Applied in vacuum metallizing
High melting point and high corrosion resistance
Good price and quality
Tungsten heater wire is 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.
