Stock Range
Sheet/plate 0.5–25 mm+, bar & tube
Stainless Steel
- 304 — corrosion resistant, general purpose
- 316/316L — superior corrosion (marine/chemical)
- 17-4 PH — precipitation hardening, high strength
Post-machining passivation on request (ASTM A967).
Carbon & Alloy Steel
- 1018 — low carbon, easy to machine, economical
- 1045 — medium carbon, stronger than 1018
- 4140 — alloy steel, high strength/toughness
Heat-treat (quench/temper) and black oxide available.
Engineering Plastics
- Delrin (POM, Acetal) — tight tolerances, low friction
- Nylon 6/66 — strong, impact resistant
- ABS — prototyping, good machinability
- PEEK — high temp/chemical resistance
We manage thermal growth and fixturing to hold tolerance.
Sheet & Plate (Laser / Machined)
- Mild steel, stainless, aluminum sheet/plate
- Typical sheet: 0.8–12 mm (material-dependent)
- Plates and blanks supplied for secondary machining
Nesting optimization to reduce cost and waste.
Certs, Traceability & Sourcing
- Mill test reports (MTR) on request
- RoHS/REACH statements available
- Lot/batch tracking on PO line items
Provide cert requirements at RFQ so we source appropriately.
DFM Tips (save cost & lead time)
- Prefer common alloys (6061-T6, 304, 1018, Delrin) unless performance requires otherwise.
- Avoid over-specifying thicknesses/grades that require special order.
- Call out cosmetic surfaces; allow tool entry and standard cutter radii.
- Bundle parts in one PO to leverage stock and setup efficiencies.
Tolerances & Finish Considerations
- Aluminum & plastics hold tight tolerances efficiently; stainless/steel may require extra passes.
- Anodize/hardcoat adds thickness; indicate if dimensions are before/after finish.
- For laser-cut parts headed to machining, leave stock allowance on critical faces.
