Material matrix
| Material group | Grades and families | Typical application | Processes |
|---|---|---|---|
| Steels | General structural, carbon, medium and high alloy, free-cutting, case-hardening steels | Shafts, gears, housings, frames | All machining, gear cutting, grinding, welding |
| Stainless steels | Austenitic, ferritic, martensitic, duplex, super duplex (1.4410 / 2507) | Food machinery, valves, pumps, rail | Milling, turning, Swiss-type, welding |
| Aluminium | 2xxx, 5xxx, 6xxx and 7xxx series | Switchgear housings, plates, aerospace parts | Milling, 5-axis, turning; alodine via supplier |
| Copper alloys | CuSnPb (leaded tin bronze) | Bushings, contact and bearing parts | Turning, milling |
| Engineering plastics | POM (incl. Delrin), ABS, PTFE | Wear parts, insulators, guides | Milling, turning |
| Titanium alloys | Ti-6Al-4V (Grade 5, 3.7165) | Aerospace brackets, housings and fittings | Milling, 5-axis, turning |
Material verification
Incoming material is checked against its certificate. Where the drawing or the customer requires it, composition is verified on our Oxford Instruments spectrometer before machining starts.
Material supply
We source material from established mills and stockists against the drawing specification.
Frequently asked questions
Do you machine super duplex stainless steel?
Yes. We machine super duplex grades such as 1.4410 (UNS S32750, "2507"). They are stronger and harder on tools than standard duplex, so cutting data, tooling and setups are planned from the first article. See the duplex machining guide.
Do you machine duplex stainless steel?
Yes — duplex grades are part of our regular work for food machinery and pump builders. See the duplex machining guide.
Do you machine titanium?
Yes. We machine the titanium alloy Ti-6Al-4V (Grade 5) on our milling, 5-axis and turning centres, typically brackets, housings and fittings for aerospace customers. Send the drawing with the material specification and we confirm the machining route and lead time.
