Product Surface
Surface Options
Cleaned – Chemically cleaned; no lubricants or oxides.
Black – As swaged or drawn; retains oxide and lubricant coating.
Finish Turning – Machined by turning for improved surface quality.
Ground – Centerless ground; precise diameter control and smooth finish.
Notes
Molybdenum easily oxidizes; mild oxidation can be removed with a soft cloth and warm water.
Cleaned surfaces may lose metallic luster.
For heavy oxide removal, professional chemical treatment is required (technical reference).
