Name

Surface Condition

Surface Color

Forged molybdenum rods

No crack, divided layer, burr, but sign with slight hammer mark is admitted.

Surface with oxide is admitted.

Straightened molybdenum rods

No crack, burr, obvious ripple, screw and dimple, but slight notch, furrow, which will not influence usage, are admitted.

The sacrificial color is always black and dark grey.

Polished molybdenum rods

forged molybdenum rod

Forged molybdenum rod

Forged molybdenum rod is also called black molybdenum rod. The surface of it is black brown, but smooth, straight, and no defect such as crack, divided layer, variole, and groove are allowed. They are mainly used for electric boosting glass kiln electrode, blender, electronic components, making different irregular molybdenum products.)

straightened molybdenum rod

Straightened molybdenum rod

When molybdenum rod has small diameter, it can be rolled into coiling as molybdenum wire. Its surface condition is required lower than black molybdenum rod, but higher than polished molybdenum rod.

Polished molybdenum rod

Polished molybdenum rod, which can also be called cleaned molybdenum rod, must have much higher requirements on its surface condition. Its surface is chemically cleaned to remove all lubricants and oxides it should presents metallic luster and has no oxidized phenomenon notably. What’s more, the surface should have no defects, such as divided   layer, crackle, burr and vertical crackle, etc.
