1,Which is the strongest type of magnet?
Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.
2,Will using magnets on my refrigerator, stove, oven, or microwave harm the appliance?
No, magnets will not harm any of these appliances.
3,Can you supply monopole magnets?
No, we don't, nor does anyone else, because they don't exist. All magnets must have at least two poles.
4,Do you stock any unplated magnets?
The iron in the NdFeB material will oxidize if it is exposed to moisture. For this reason, we do not stock any unplated magnets. We can supply unplated magnets as custom order items.
5,How can I get the sample?
Samples in stock can sent out within one day, free samples accordingly, Express fee paid by customers.If samples not in stock, 7-15 days manufacture, and we charge sample fee and express fee.
6, Are you the magnet manufacturer?
Yes, our own factory is in Zhejiang, our Trading office (HCM) is in ShanXi.
