If you need to buy magnets, please cooperate with us to confirm the following information:1. Material and properties of magnet.2. Dimensions and corresponding tolerances.3. Whether to magnetize or not, if so, what is the direction of magnetization, axial or radial direction, and whether the magnetic pole needs to be marked by points.4. The maximum temperature that the magnet will reach in the working environment.5. Quantity required.6. Magnet coating: galvanized, nickel plated, gold plated, or epoxy resin.7. Do you need air transportation so that we can conduct magnetic separation packaging?
