Published typical values for 6061-T6. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Thin walls relax after roughing. We rough, let the part stabilise, then finish — otherwise a 1.5 mm wall bows by more than the tolerance it was cut to.
Machining 3105 Aluminum with CNC Press Brake Forming
3105 Aluminum behaves predictably under CNC Press Brake Forming once parameters are dialled in: machinability is excellent; high cutting speeds and superb finishes achievable, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of 3105 Aluminum run consistently from one batch to the next.
Achievable Tolerances for CNC Press Brake Forming 3105 Aluminum
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 mm |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Design Tips for CNC Press Brake Forming 3105 Aluminum
We are happy to suggest design tweaks that improve manufacturability. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed 3105 Aluminum. If you send your model early, we will return practical DFM feedback before you commit to production.
Why 3105 Aluminum?
3105 Aluminum is chosen when a part needs what this grade offers — it is lightweight with excellent machinability. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC Press Brake Forming Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every 3105 Aluminum part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
CNC Press Brake Forming Tolerances & Surface Finish
Formed 3105 Aluminum holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Secondary Operations & Finishing
Finished 3105 Aluminum parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Applications of CNC Press Brake Forming 3105 Aluminum
Customers order CNC Press Brake Forming 3105 Aluminum components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.
How to Order CNC Press Brake Forming 3105 Aluminum
Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
Finishing Options for 3105 Aluminum
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Clear anodise (Type II) | 5–25 µm | Corrosion protection, keeps the natural colour |
| Colour anodise | 10–25 µm | Black, red, blue, gold; add 0.02 mm to close tolerances |
| Hard anodise (Type III) | 25–50 µm | 60–70 HRC surface, grows 50% into the part |
| Chromate / Alodine 1200 | < 1 µm | Conductive, meets MIL-DTL-5541 |
| Powder coat | 60–120 µm | RAL colours, needs 0.3 mm clearance on mating features |
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Press Brake Forming 3105 Aluminum
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact 3105 Aluminum grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.
