High Purity Customized Polished Tungsten Rod,Tungsten Round Rod
Brief introduction:
Tungsten rodis 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.
Applications:
Tungsten rod is widely used to produce cathode, components for
electron tubes, grid siderod, lead, support, etc.
Appearance:
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
