Materials & Finishes
Material and finish choices directly affect CNC machining cost, lead time, appearance and part performance. Sendot Technology helps customers compare practical options for prototypes, small batches and production parts.
Common CNC Metal Materials
- Aluminum is lightweight, easy to machine and suitable for anodizing or cosmetic finishes.
- Stainless steel offers corrosion resistance and strength for demanding environments.
- Brass is useful for electrical, decorative and precision components.
- Carbon steel and alloy steel are often selected for strength, wear resistance and functional parts.
Surface Finish Options
- Anodizing improves aluminum appearance and corrosion resistance.
- Bead blasting creates a uniform matte surface before finishing.
- Plating can improve corrosion resistance, conductivity or wear performance.
- Polishing and brushing are used when visual appearance is important.
How to Choose
Start with the part function, environment, load, appearance requirement and target quantity. If you are not sure which material or finish is best, Sendot can review your application and suggest practical options before machining.
