VT machining offers CNC Milling for 1070 Aluminum (UNS A91070 / EN AW-1070A), typically supplied O / H14. Higher purity grade for conductivity and anodised finish.
CNC Milling Notes for 1070 Aluminum
1070 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 1070 Aluminum weighs about 0.27 kg.
