Materials
Alloys we source, by family
Certified stock with mill test certificates traced to heat and lot. The relative cycle-time factor drives our lead-time model; it is not a price factor.

Need an alloy not listed? Add it as a note on the RFQ line. It is routed for manual review with a sourcing check before we quote. We do not decline on the alloy alone.
Finishes
Every finish names its specification
A finish call-out without a specification is not one we accept on a drawing or publish here. Where a treatment has no governing standard, the parameters are agreed in writing per job.
| Item | Governing specification | Added lead time | Applies to |
|---|---|---|---|
Bead blast | Media and pressure recorded per job | +1 working days | Aluminium, Titanium, Corrosion-resistant steel, Nickel alloy, Magnesium |
Anodise Type II | MIL-A-8625 Type II, Class 1 & 2 | +3 working days | Aluminium |
Hard anodise Type III | MIL-A-8625 Type III | +3 working days | Aluminium |
Chemical conversion | MIL-DTL-5541 Type I / II | +3 working days | Aluminium |
Passivation | ASTM A967 / AMS 2700 | +2 working days | Corrosion-resistant steel |
Titanium anodise | AMS-2488 Type 2 | +3 working days | Titanium |
Electroless nickel | MIL-C-26074 | +4 working days | Aluminium, Titanium, Corrosion-resistant steel, Nickel alloy, Magnesium |
Vacuum bake-out | Profile agreed per programme | +4 working days | Aluminium, Titanium, Corrosion-resistant steel, Nickel alloy, Magnesium |
Inspection
Inspection levels
Chosen per line on the RFQ. Where a vendor or an accredited lab took the measurement, our report says reviewed by or witnessed by, never inspected by.
| Item | Added lead time | Included |
|---|---|---|
Standard dimensional | No added time | On every line |
First Article (AS9102) | +1 working days | On request |
Full CMM report | +2 working days | On request |
CMM + NDT (DPI/UT) | +3 working days | On request |
