Machinability
Aluminum usually machines efficiently, but thin walls, deep pockets and cosmetic surfaces still require DFM review.
- Good for milling and turning
- Suitable for anodized parts
- Useful for prototype-to-production

Cost and tolerance impact
Aluminum can reduce machining time, but tolerance stability depends on geometry and wall thickness.
- Thin sections may deform
- Anodizing may change dimensions
- Critical features need clear inspection notes
Industry usage
Common in UAV, robotics, electronics and industrial equipment.
- Lightweight brackets
- Housings and frames
- Heat sink style components
Engineering Trade-Offs
Lightweight and efficient but less stiff than steel
Good cosmetic finish but anodizing needs planning
Complex thin-wall parts need careful fixture strategy
