Cobalt chrome / CoCr
- Alternative Designations: CoCr | F - 75 (ASTM)
Description:
Cobalt Chrome is a high corrosion resistance alloy. The formation of a passive film of Cr203 protects the primary material of this alloy. The mechanical properties are excellent due to increased hardness and tensile strength. This alloy has seen wide applications in the medical and dentistry industries due to its biocompatibility, wear resistance, and chemical inertness. In addition, it is used in the production of wind turbines, cutting tools, and other mechanical parts that require high wear – resistance.

CNC machined part without surface finishes (3D render, aluminium)Bead blasting (3D render)
Bead blasting
Bead blasting involves spraying a pressurised stream of tiny beads of media, plastic or glass beads, from a nozzle onto the surface of the part. This removes the burrs and imperfections, leaving a smooth finish.
Notes:The recommended part size is 6-600 mm in both height and width. Smaller parts are hard to hold and tough to produce an even surface.
Final result:
- Uniform, matte or satin-like appearance
- Slightly grainy in the touch

Custom Finishing
If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually takes 1-2 business days.
Notes:Submitting for manual review with a custom request does not guarantee a quote.
