Measurements

Pot magnet has a particular magnetic circuit that can concentrate or insulate magnetic power at a target space around the magnetic assembly.
1. Materials: Permanent magnets(ferrite, alnico, NdFeB) and metal or steel.
2. Application: Pot magnets hold things you need to keep within easy reach. Such as in jobber vans, workshops, auto repair and service stations, or even in the warehouse.
3. Available in different forms and shapes, which are finished in white, black, gray, Nickel or Zinc coating, or rubber covered

1) Cheapest magnet material
2) Good anti-corrosion performance, no need to surface treatment.
3) Best temperature stability
4) Best choice for industrial application
5) All shapes can be customized
6) Compact crystal
7) provide isotropic and anisotropic
8) OEM service
