1. Material and performance of magnets.
2. Dimensions and corresponding tolerances.
3. Do you want to magnetize? If so, what is the direction of magnetization, axial or radial, and whether magnetic poles need to be marked with dots.
4. The maximum temperature that a magnet can reach in its working environment.
5. Quantity required.
6. Coating of magnets: galvanized, nickel plated, gold plated, or epoxy resin.
7. Do you need air freight so that we can process the magnetic barrier packaging.
