Material condition
Put the full grade, standard and temper on the drawing. A grade number alone does not define the supplied condition.
Metal / CNC MATERIALS
Aluminum CNC Machining
Also known as: Aluminium
Custom aluminum parts, from a first prototype to repeat orders. We regularly machine 2011, 5083, 6060, 6061, 6082 and 7075.

6061 or 6082: what actually changes the order?
Compare the temper and available product form first. A stronger reference value for one extrusion does not establish the properties of a plate, a different thickness or your supplied lot. Keep the drawing grade unless an alternative has been approved; check anodizing, stock size and final fits alongside strength.
01 / MATERIAL SPECIFICATION
Aluminum grades & conditions.
Match the full designation on your drawing. Frequent machining experience, published project evidence and specifications for review are shown separately.
| Grade / designation | Experience | Include with your drawing | Inquiry |

| 5083 | Regularly machined | Specify the temper and any welded or finished features in the project. | Quote grade ↗ |
| 6060 | Regularly machined | Include the temper and profile drawing if the part starts from an extrusion. | Quote grade ↗ |
| 6061 | Regularly machined | Specify the temper, finish and dimensions that apply after finishing. | Quote grade ↗ |
| 6082 | Regularly machined | Include the exact temper. Our published 6082 case does not state a temper. | Quote grade ↗ |
| 7075 | Regularly machined | Specify the temper. The published planet-carrier project used 7075-T6. | Quote grade ↗ |
| 6063 | Published project | Documented ball-head screw production; the published temper is unspecified. | Quote grade ↗ |
| 2024 | Specify for review | Send the exact grade and temper for sourcing and process review. | Quote grade ↗ |
OUJI machining experience: confirmed by the company owner, 10 September 2026. Family-level experience does not establish a specific grade, stock condition or customer end use; see individual row and case evidence.
Listed grades do not imply current inventory. Material condition, stock form and documentation are agreed with the quotation.
02 / MACHINING REQUIREMENTS
Make the drawing ready for review.
Focus on the details that change material purchasing, the machining route and finished-part acceptance.
Thin walls & multiple faces
Identify functional datums and critical features so fixturing and the machining sequence can be reviewed together.
Anodizing & final dimensions
State which dimensions apply after anodizing, plus coating requirements, masked areas and cosmetic faces.
Planning an optical instrument enclosure or mount? Review port locations, thin walls and dimensions after anodizing in our photonics mechanical parts guide.
SUPPLIER REFERENCE DATA
6061 and 6082: sourced extrusion examples
Minimum values for the named supplier products and section ranges. Use the required stock specification and lot documents for purchasing.
| Supplier product / scope | Tensile strength, minimum | 0.2% proof / yield strength, minimum | Basis / version | Source |
|---|---|---|---|---|
| Hydro 6061-T6 / T6511 extrusion; wall ≤ 6.30 mm | 260 MPa | 240 MPa | Bulletin revision 2019/01 (2/2019); tensile test standard not stated | Hydro — Alloy 6061PDF (opens in a new tab) |
| Hydro EN AW-6082 T6 flat profile; t ≤ 5 mm | 290 MPa | 250 MPa | EN 755-2 property basis; declaration 26 March 2024; test method not separately stated | Hydro — EN AW-6082 T6 declarationPDF (opens in a new tab) |
| Hydro EN AW-6082 T6 flat profile; 5 < t ≤ 25 mm | 310 MPa | 260 MPa | Same declaration; thickness range is part of the value | Hydro — EN AW-6082 T6 declarationPDF (opens in a new tab) |
These are extrusion references, not plate properties or OUJI inspection results. EN 755-2 is a product/property standard, not a test-method claim. No automatic substitution between 6061 and 6082 is implied.
03 / PROJECT EXPERIENCE
Aluminum in the workshop.
Read the actual machining route and evidence for each project. Requirements and individual inspection results retain their original scope.
EN AW-6082 aluminum; exact temper not published
Holding 0.02 mm Position in EN AW-6082 Aluminum with 3+2 CNC Machining
- Drawing requirement
- ⌀0.02 mm position to datums A | B | C
- Production process
- Datum-led dovetail setup with 3+2 indexed milling
What this case documents
Production confirmation reports the critical dimensions as OK, but the public case does not include measured values, inspection footage, cycle time or material temper.
5083 aluminum
5083 Aluminum CNC Turning: Improving Surface Consistency
- Project quantity
- 1,000 parts for optical equipment
- Production process
- Feed optimization and revised tool selection
What this case documents
The project owner confirms 5083, the order quantity, machining changes and rework. The approximate production figures describe appearance: about 40% initially and nearly 90% after optimization. They are not final delivery results. Material temper and numerical roughness are unspecified.
Aluminum alloy; exact grade and temper not published
Selective Machining After Black Anodizing on an Aluminum Prototype
- Production process
- Black anodizing followed by selective secondary machining
- Drawing requirement
- Specified surfaces left as clean bare aluminum
What this case documents
The photographs document the finished surface transition. No numeric inspection result, coating-thickness report or material certificate is published.

Is 6082 a direct replacement for 6061?
No substitution is assumed. Compare the specified product standard, temper, section thickness and required mechanical properties. The sourced extrusion examples below have different dimensional scopes; they are a starting point for discussion, not interchangeable purchasing specifications.
Does frequent machining mean a listed alloy is in stock?
No. The confirmed list describes machining experience. Availability of a particular diameter, plate thickness, temper and mill document is checked for each quotation.
Which dimensions should I mark for anodized aluminum?
Mark the dimensions accepted after anodizing and any areas that must remain uncoated. A bore fit, a threaded feature and a cosmetic face can require different masking and inspection decisions.
