VT machining offers CNC Milling for 1050 Aluminum (UNS A91050 / EN AW-1050A), typically supplied O / H14. Commercially pure; very soft and gummy, so sharp polished tools and high rake are needed.
CNC Milling Notes for 1050 Aluminum
1050 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 1050 Aluminum weighs about 0.27 kg.

Request a QuoteFrequently Asked Questions
Does CNC Milling 1050 Aluminum require dedicated tooling?
Most 1050 Aluminum machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What material thickness or size range suits CNC Milling 1050 Aluminum?
We machine 1050 Aluminum across a broad size range; share your part envelope for confirmation.
What is the typical lead time and minimum order for CNC Milling 1050 Aluminum?
CNC Milling prototypes for 1050 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 Milling 1050 Aluminum?
Achievable tolerances for 1050 Aluminum machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom 1050 Aluminum parts to my drawing?
Yes. 1050 Aluminum machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
Why is 1050 Aluminum a good choice for CNC Milling?
1050 Aluminum is lightweight with excellent machinability, which makes it well suited to CNC Milling. We tune the process to the alloy so the finished 1050 Aluminum machining part meets your dimensional and functional requirements.
