Strong Neodymium Disc Magnets. Round Circle Magnets are made from the strongest magnetic material, Neodymium (NdFeB). Available in various sizes from 1mm diameter to over 120mm diameter. Neodymium disc magnets are commonly found in point of sale display units, stationery folders, scale models and industrial applications. Neo Disc Magnets are truly versatile and are used as widely in homemade arts and crafts as they are in high-end technology and engineering applications.
Neodymium magnets are most powerful of any kind of magnetic materials
Br of neodymium magnets are much more than 11,000 Gauss. Therefore, Neodymium magnets have strong holding strength on metal surface and could be used as component for holding, separating, etc. Neodymium magnets must be carefully handled to avoid personal injury and material damage due to its extremely magnetic strength and brittle property.
Neodymium magnets are sensitive to temperature change and even lose magnet properties at high temperature
Neodymium magnets lose -0.09 ~ -0.13% of Br/oC and can work stably under 80oC for low Hci Neodymium magnets and 150oC for high Hci Neodymium magnets. Quadrapolar Magnet Disc N30AH Zn Coating
Neodymium magnets are corrupted in humid environment, Round Neodymium Iron Boron N42SH Magnets
Surface protection is strongly recommended, such as plating, varnishing and encapsulating.
Neodymium magnets are hard and brittle, Round Neodymium Iron Boron N42SH Magnets
Neodymium magnets can be abrasively machined with coolant served to absorb heating and dust. Without coolant, rare earth magnets could crack and chip by the heat produced during high speed cutting or grinding, and the sparks contain the easily oxidized grinding dust that could cause fire!
