What surface finish is achievable on 1100 Aluminum with CNC Polishing?
Our finishing processes refine 1100 Aluminum surfaces to Ra values as low as 0.05 µm for cosmetic or sealing faces.
What is the typical lead time and minimum order for CNC Polishing 1100 Aluminum?
CNC Polishing 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.
Can VT machining make custom 1100 Aluminum parts to my drawing?
Yes. 1100 Aluminum finishing 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 1100 Aluminum a good choice for CNC Polishing?
1100 Aluminum is lightweight with excellent machinability, which makes it well suited to CNC Polishing. We tune the process to the alloy so the finished 1100 Aluminum finishing part meets your dimensional and functional requirements.
