VT machining offers CNC Milling for 1100 Aluminum (UNS A91100 / EN AW-1200), typically supplied O / H14. Small Cu addition gives slightly more strength than 1050 while keeping formability.
CNC Milling Notes for 1100 Aluminum
1100 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 1100 Aluminum weighs about 0.27 kg.
