Tungsten parts Tungsten Faced copper welding electrode used for
copper wire welding, enameled wire welding
Counting on our wide industry experience, our organization is
involved in manufacturing and supplying an excellent quality range
of Tungsten Faced Electrode Shaft.
It is used for copper wire welding, enameled wire welding, copper
lug welding, copper foil welding and copper crossing wire welding.
The electrode shaft is used for flash and butt welding electrodes
in applications in which high heat resistance, high malleability,
and low thermal expansion are required.
Tungsten Faced Electrode Shaft is also used in the liners of some specialty shaped explosive
charges for the defense and oil and gas industries.
Features:
Higher thermal conductivity
Wear resistant
Easy to use
