VT machining offers CNC Milling for 3003 Aluminum (UNS A93003 / EN AW-3003), typically supplied H14. Mn adds ~20% strength over 1100 with excellent formability.
CNC Milling Notes for 3003 Aluminum
3003 Aluminum mills well with conventional strategies; finishing passes are planned to meet flatness and finish callouts.
For estimating, a 100 × 100 × 10 mm block of 3003 Aluminum weighs about 0.27 kg.
