Metal Post-Processing Capabilities
After CNC machining, metal parts can undergo various post-processing treatments to enhance corrosion resistance, hardness, and appearance:
| Process | Applicable Materials | Effect |
|---|---|---|
| Shot Blasting | Aluminum, Stainless Steel, Magnesium Alloys | Uniform matte surface, eliminate tool marks |
| Anodizing | Aluminum Alloys | Increased hardness, corrosion resistance, available in natural color/black/red/blue, etc. |
| Hard Anodizing | Aluminum Alloys | Higher hardness (HV300-500), wear resistance |
| Nitriding | Stainless Steel, Alloy Steels | Surface hardening (HV800-1200), improved wear resistance |
| Electrocoating + Powder Coating | Carbon Steel, S550MC | Black uniform coating, excellent rust prevention performance |
| Polishing | Stainless Steel, Aluminum | Mirror or high-gloss surface |
| Passivation | Stainless Steel | Enhanced corrosion resistance |
