The quality requirements of Tungsten rod surface
| Surface state | Surface color |
Forged tungsten rod | No cracks, delamination, burrs, allowing a slight traces of forging | Allows oxygen Membrane |
Sintering tungsten rod | No cracks, burrs and obvious ripples, thread, pits, allowing a slight nick does not affect the use of trench | Black to dark gray |
Polished tungsten rod | Allowed to have cracks, vertical lines and traces of roughness |
