neodymiumring

Permanent neodyme magnet ring type AN 03 Neodynium magnetHigh holding power The Neodymium (rare earth) magnet (also known as NdFeB, NIB or Neo magnet) they are sintered magnets composed of NdFeB powder. A Surface treatment is necessary for corrosion protection (Zinc-Nickel-Or-Epoxy). The Neodymium Fer Bore magnets have a very high magnetic strength and a high resistance to demagnetization. They are fragile ceramics and its strength is highest when the magnet is in contact with a mild steel, that is clean and thick enough. The strength is reduced when in contact with alloy steels (cast Iron -30%), due to air-gap or a high temperature (-0.11% per degree C). Neodymium magnets are not machinable, they can not be cut or drilled. and mounting is done with glue. Magnetized depending on thickness.
