N35 8mm Dia X 1mm Easypeel Neodymium Adhesive Magnet

These thin but powerful Neodymium self-adhesive magnets combine the performance of Neodymium with the convenience of self-adhesive making them ideal for creating fridge magnets, book and folder closures, packaging, retail displays and craft making. Remember, if using two together to attract you will need to make sure each has opposite poles on the non-adhesive side.

Each magnet's north pole is on the non-adhesive face and the south pole is on the self-adhesive face
Convenient super-strong 3M 468 adhesive with easy-peel tab
Each magnet can support a steel weight of up to 0.44kg vertically from the magnetic face when in flush contact with a mild steel surface
Excellent resistance to demagnetisation
Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish
Neodymium Magnets are composed of Neodymium, Iron and Boron. Density of Neodymium magnets is. 27Lb/in3 (7.5g/cm3).
Neodymium Magnets are manufactured in a metallurgy process through alloying, crushing, powdering, pressing w/magnetic orientation, sintering, then cutting, coating, inspecting and packing before shipment.
Neodymium Magnets offer the highest (BH)max and high Hci(BH)max, the Maximum Energy Product, of Neodymium magnets is highest of any kind of permanent magnets today in the world. (BH)max at different grades of Neodymium magnets is 27 to 52 MGOe. Neodymium magnets have extremely resistance to demagnetization with Hci, Intrisic coercive force, over 12, 000 Oe. Because of very high (BH)max and Hci, Neo magnets could be used as a reversible medium for large amount of energy transformation in miniaturized application where a strong magnetic demagnetization field exists, such as computer hard drive. Disk and rectangle shapes for customers' immediate needs and accept special orders for custom Neodymium magnets.
Neodymium Magnets are most powerful of any kind of magnetic materialsBr 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 temperatureNeodymium magnets lose -0.09 ~ -0.13% of Br/° C and can work stably under 80° C for low Hci Neodymium magnets and 150° C for high Hci Neodymium magnets.
Neodymium magnets are corrupted in humid environment Surface protection is strongly recommended, such as plating, varnishing and encapsulating.
Neodymium Magnets are hard and brittle 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!
