VT machining offers CNC Punching for 3003 Aluminum (UNS A93003 / EN AW-3003), typically supplied H14. Mn adds ~20% strength over 1100 with excellent formability.
CNC Punching Notes for 3003 Aluminum
3003 Aluminum punches cleanly with standard clearance; minimum hole diameter is about the sheet thickness.
For estimating, a 100 × 100 × 10 mm block of 3003 Aluminum weighs about 0.27 kg.

What is CNC Punching 3003 Aluminum and how is it done?
CNC Punching 3003 Aluminum refers to cNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. Applied to 3003 Aluminum — lightweight with excellent machinability — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What surface finish is achievable on 3003 Aluminum with CNC Punching?
Surface finish on 3003 Aluminum is controlled to your specification; we confirm the achievable Ra against your callout.
What is the typical lead time and minimum order for CNC Punching 3003 Aluminum?
CNC Punching prototypes for 3003 Aluminum can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Punching 3003 Aluminum?
Achievable tolerances for 3003 Aluminum punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Punching 3003 Aluminum?
Punching suits 3003 Aluminum sheet roughly 0.5–6 mm thick, with clearance matched to the gauge.
