Bonded Neodymium magnets are composed of Neodymium, Iron, Boron and binder. Bonded Neodymium magnets are manufactured by compression molding or injection molding. Compression bonded Neodymium magnets have higher energy products and simpler shapes than injection bonded Neodymium magnets. There are both isotropic and anisotropic bonded Neodymium magnets.
Magnetic property of Boded Neodymium magnets:
High Energy Products. Very high resistance to demagnetization. Low operating temperature (under 80 to 150°C). For details, see the table of Bonded Neodymium Magnetic property.
Oxidation to Bonded Neodymium magnets:
Easy to be oxidized at its surface in wet air. Normally, they are plated with lacquer or Nickel.
Physical property of Bonded Neodymium magnets
Dark gray in color. Hard and brittle. Density of Neo is .22Lb/in3 (6.1g/cm3).
Tolerance of Bonded Neodymium magnets:
Unless otherwise specified, tolerance on dimension of magnetization is ±.005”. Other dimensions are ±1.5% or ±.010”, whichever is greater.
Handling Bonded Neodymium magnets:
Must be careful to avoid personal injury and material damage due to its extremely magnetic strength and brittle property.
