tungsten rod
Tungsten rod is widely used to produce cathode, components for electron tubes, grid siderod, lead, support, etc.
Brief introduction:
Tungsten rod is divided into firing tungsten rod, forging tungsten rod and polishing tungsten rod according to different production processes. The crystal structure of tungsten rod is compact.
The surface of firing tungsten rod appears silver gray metallic luster;
The surface of forging tungsten rod has a layer of oxide and slight forging hammer mark, so the surface is black;
The surface of polishing tungsten rod appears silver gray metallic luster and has no obvious oxidized phenomenon.

Applications of tungsten rod:
Tungsten rod is widely used to produce cathode, components for electron tubes, grid siderod, lead, support, etc.Appearance of tungsten rod:
Tungsten rod has no camber, crack, burr, peeling or other defects affecting the further uses.The surface of firing tungsten rod appears silver gray metallic luster;
The surface of forging tungsten rod has a layer of oxide and slight forging hammer mark, so the surface is black;
The surface of polishing tungsten rod appears silver gray metallic luster and has no obvious oxidized phenomenon.
CLOT Co., Ltd can produce required tungsten rod according to customers’request. We also provide tungsten carbide rod and tungsten welding rod.
