Why Aluminium
Aluminium offers an excellent strength-to-weight ratio, good corrosion resistance and superb machinability — so parts are produced fast, accurate and economical. It is the default choice for equipment structures, enclosures and motion parts where weight matters.
We hold tight tolerances and good surface finishes on aluminium and integrate anodizing and other finishes through our process. CNC Machining · Tight Tolerance
Common Grades We Machine
| Grade | Character | Typical use |
|---|---|---|
| 6061-T6 | General-purpose, weldable, corrosion-resistant | Brackets, frames, housings |
| 7075-T6 | High strength | Structural, load-bearing parts |
| 5083 / 5086 | Marine-grade corrosion resistance | Subsea, outdoor equipment |
| 6082 | European general-purpose (EN AW-6082) | Structural components |
| MIC-6 / cast plate | Stress-relieved, stable | Bases, precision plates |
Machining Notes
- High speeds — aluminium cuts cleanly at high spindle speeds
- Surface finish — easily achieves fine Ra
- Finishes — anodizing (clear, black, hard coat) for protection and appearance
- Stability — stress-relieved plate for precision bases
Quality, Inspection & Traceability
For equipment manufacturers, one failed component can stop a production line or compromise a field product. ProtoTech provides dimensional inspection, inspection reports, material certification and full traceability — so your quality team can qualify us for recurring production with confidence.
Our in-house metrology includes a Zeiss coordinate measuring machine (CMM) for full dimensional inspection and First Article Inspection (FAI), plus a benchtop material spectrometer that verifies incoming stock against the specified grade. Every shipment can be supplied with EN 10204 3.1 material certificates and lot-level traceability, backed by ISO 9001:2015 (AENOR).
