VT machining offers CNC Turning 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 Turning Notes for 1100 Aluminum
1100 Aluminum turns with good chip control at standard cutting data.
For estimating, a 100 × 100 × 10 mm block of 1100 Aluminum weighs about 0.27 kg.

What is the typical lead time and minimum order for CNC Turning 1100 Aluminum?
CNC Turning prototypes for 1100 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 Turning 1100 Aluminum?
Achievable tolerances for 1100 Aluminum turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
Does CNC Turning 1100 Aluminum require dedicated tooling?
Most 1100 Aluminum turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is 1100 Aluminum a good choice for CNC Turning?
1100 Aluminum is lightweight with excellent machinability, which makes it well suited to CNC Turning. We tune the process to the alloy so the finished 1100 Aluminum turning part meets your dimensional and functional requirements.
How clean are the edges produced by CNC Turning on 1100 Aluminum?
Machined 1100 Aluminum edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What is CNC Turning 1100 Aluminum and how is it done?
CNC Turning 1100 Aluminum refers to cNC turning rotates the workpiece against a single-point tool to produce cylindrical features, threads and grooves. Applied to 1100 Aluminum — lightweight with excellent machinability — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
