Industrial Magnetic Holding Magnets

Precision Magnetic Solutions for Industrial Fixing, Positioning, and Assembly

Aohong Magnet is a trusted global manufacturer and wholesale supplier of industrial magnetic holding components, serving equipment builders, automation integrators, and OEM manufacturers worldwide. Our holding assemblies are engineered to securely clamp, fix, or position metal components without mechanical fasteners, utilizing optimized magnetic circuits and protective housings to withstand the most demanding operational environments.

Backed by strict ISO9001 quality management and full compliance with international environmental standards (RoHS & REACH), we ensure dependable, batch-to-batch consistency for global supply chains.

Selecting the correct magnetic material determines the holding force, thermal stability, and corrosion resistance for your specific operating conditions:

Neodymium (NdFeB - Grades N35 to N52): Selected when maximum magnetic energy density is required within a compact installation footprint. Best suited for high-load automation fixtures and robotic tooling operating up to 80°C to 200°C (depending on coercivity grade).

Samarium Cobalt (SmCo): Specified for high-temperature environments or corrosive chemical processing. It maintains stable magnetic flux at temperatures exceeding 250°C and exhibits strong natural resistance to oxidation without heavy coatings.

Ferrite (Ceramic - Grade Y30BH / Y35): Utilized for high-volume, cost-sensitive applications where moderate holding force and broad chemical resistance are acceptable. Ferrite components are chemically inert and perform reliably up to 250°C.

Alnico: Applied in specialized high-temperature applications or environments requiring exceptional magnetic stability against thermal fluctuations.

Elimination of Mechanical Fastening: Replaces screws, drilling, and mechanical clamps with surface-contact magnetic attraction, significantly reducing assembly time and preventing workpiece deformation.

Controlled Magnetic Circuits: By housing magnets inside steel cups (pot magnets) or steel channels, the magnetic flux is redirected and concentrated toward the contact surface, dramatically increasing the perpendicular pull-force compared to open magnets.

Repeatable Positioning: Maintains tight dimensional and positional tolerances across repetitive automated cycles, minimizing alignment drift during high-speed production runs.

Standard catalog magnets often fail to meet specific equipment integration requirements. We provide full-cycle OEM/ODM customization based on your mechanical drawings:

Geometry: Block, disc, ring, countersunk pot magnets, and custom channel assemblies.

Mounting Features: Integrated internal threads (metric/imperial studs), countersunk through-holes for flat-head screws, threaded boss attachments, or custom welded brackets.

Surface Protection & Friction Enhancement:
Ni-Cu-Ni (Nickel): Provides standard industrial wear and corrosion resistance.

Epoxy: Enhanced defense against moisture and salt-spray.

Rubber coating (Santoprene/EPIC): Increases lateral friction while protecting painted, polished, or sensitive mounting surfaces from scratching.

Automation & Robotics: End-of-arm tooling (EOAT), sensor mounting brackets, and quick-change fixture plates.

Machinery & Tooling: Removable machine guards, precision inspection jigs, and temporary welding positioning stops.

Enclosures & Access Control: Latches for heavy-duty industrial cabinet doors, cleanroom access panels, and electrical enclosures requiring consistent retention force without mechanical wear.
