Metal + Magnets from One Supplier
Naturally Complementary
Most magnet assemblies need precision metal components — rotors need shafts, couplings need hubs, Halbach arrays need back-irons. Our supply team coordinates owned magnetic production and strategic metal-manufacturing bases.
Consolidated Shipping
Magnets and metal parts ship together from Ningbo. One PO, one shipment, one quality framework — lower landed cost and faster receiving.
DFM Across Processes
Our engineers optimize across the whole BOM: we compare feasible processes, tooling, finishing and inspection needs against the part and production volume.
Process Comparison
| Process | Materials | Typical Tolerance | Surface Finish | MOQ |
|---|---|---|---|---|
| Die Casting | A380, ADC12, A360, Zamak | ±0.1mm (as-cast) | Ra 1.6–3.2µm | 500 pcs |
| Investment Casting | 304, 316, 17-4PH, carbon steel, brass | ±0.1mm (CT4–5) | Ra 3.2–6.3µm | 100 pcs |
| Forging | 1045, 4140, 4340, stainless | ±0.5mm (as-forged) | Ra 6.3–12.5µm | 200 pcs |
| CNC Machining | Al, steel, stainless, brass, plastics | ±0.005–0.01mm | Ra 0.4–1.6µm | 1 pc |
| Extrusion | 6061, 6063, 6005A | ±0.15mm (profile) | Ra 0.8µm (anodized) | 200 kg |
