VT machining offers CNC Milling for 3004 Aluminum (UNS A93004 / EN AW-3004), typically supplied H34. Mg addition makes it stronger than 3003; can-body alloy.
CNC Milling Notes for 3004 Aluminum
3004 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 3004 Aluminum weighs about 0.27 kg.
