Introduction:
Tungsten rod is divided into firing W rod, forging W rod and polished W rod according to different production processes. The crystal structure of w rod is compact.
Applications:
W rod is widely used to produce tungsten wire, cathode, components for electron tubes, grid siderod, lead, support, etc.
Appearance:
W rod has no camber, crack, burr, peeling or other defects affecting the further uses.
The surface of firing W rod appears silver gray metallic luster;
The surface of forging W rod has a layer of oxide and slight forging hammer mark, so the surface is black;
The surface of polishing W rod appears silver gray metallic luster and has no obvious oxidized phenomenon.
Aceon can provide required W rod according to customers’request. We also provide tungsten carbide rod and tungsten welding rod.
Tungsten rod and other tungsten products are all industrial products. These tungsten products are manufactured by special factory. Whether it is 99.95%, 99.96%, 99.97%, 99.98% tungsten rod or 99.99% tungsten rod, all tungsten rods are made by Powder Metallurgy Method.
The followings are several production steps of Tungsten Rod:
Step one: Produce tungsten powder. Manufacturers need ensure the purity and particle size of tungsten powder. Ore of tungsten adds ammonium tungstate, after two reduction and purification, tungsten powder is made.
Step two: Put tungsten powder into leather sheath, hammer the tungsten powder into rod shape by using machine.
Step three: Then put the tungsten rod embryonic form into high temperature to sinter by using sintering furnace.
Step four: Finish tungsten rod producing by hammering, straightening and grinding.
Aceon can provide customized tungsten rods according to the requirements of customers. We are also able to offer tungsten rod samples.
