SELECTION GUIDEGeometry, coating, magnetization and handlingExplore applications and requirements
Any Shape, Any Tolerance
Blocks, discs, rings, arcs, and custom geometries. Tight tolerances via centerless grinding and profile machining — down to ±0.02mm on critical dimensions.
Full Coating Options
Ni-Cu-Ni, epoxy, zinc, phosphate, and Parylene coatings. Salt-spray tested to your spec. We recommend coating based on your operating environment — not just what's cheapest.
Magnetization In-House
Axial, radial, diametric, and multi-pole magnetization patterns. We verify flux output on every magnetized lot before shipment.
Handling & Packaging
Specify separation, part orientation and protection requirements for safe handling during shipment and assembly.
Include packaging requirementsWhat to Include in Your RFQ
