Aluminum vs Stainless Steel for CNC Parts
Aluminum (6061/7075) machines faster and lighter — ideal for brackets, frames, and drone structures.
Stainless (304/316) resists corrosion and looks premium, but cuts slower and costs more in cycle time.
Rule of thumb: indoor structures → aluminum; washdown / marine / chemical exposure → stainless. Share the environment in your RFQ.
