Tungsten rod can be manufactured in random length pieces or
cut to meet customers' desired lengths. There are three
different surface processes which are provided upon the
desired end use:
1.
Black tungsten rod - Surface is "as swaged" or "as drawn";
retaining a coating of processing lubricants and
oxides;
2.
Cleaned tungsten alloy rod- Surface is chemically cleaned
to remove all lubricants and oxides;
3.
Ground tungsten rod- Surface is centerless ground to remove
all coating and to achieve precise diameter
control.
Features: pure
tungsten welding rod
The
outstanding feature of tungsten rod is that they can be
batch operated. Among the rod-like metal materials,
tungsten rod has the highest melting point. In heat,
electric conduction and electron emission, it performs very
well. The tungsten rod is also characterized by high
density, low dilatation coefficient and lowest metallic
vapor pressure.he density of our tungsten rod is higher
than 18.8g/cm3; purity, 99.5%. This has met the GB 4187-84
and AKM QB/WB-2006 Standard.

Application:
Tungsten rods are mainly used as heater, support pillar, feeder and fastener in vacuum or reducing atmosphere high temperature furnace. Moreover, serve as light source in lighting industry, electrode in glass and tombarthite melting, and welding equipments manufacture emitting cathode, high temperature setting lever, support, lead, print needle and all kinds of electrodes and the quartz furnace heater.
