Bonded Ferrite e Sam/Co

Product catalog summary
Overview: The document discusses the technical specifications and applications of bonded magnets, specifically those made from ferrite, samarium cobalt, and neodymium. These magnets are produced through injection or compression molding, allowing for customized magnetic properties and high mechanical strength.
Specifications:
  • Bonded magnets can be made by mixing plastic materials with powders of barium or strontium carbonate, samarium cobalt, and neodymium.
  • These magnets exhibit reduced size tolerances and high mechanical solidity.
  • They allow for overmolding with other plastic or metal parts such as rotors and stators.
Magnetic Properties:
  • Residual induction and coercive force can be customized according to requirements.
  • Different grades of magnets (e.g., NP5, NP8, NP12) have varying magnetic properties such as remanence (Br), coercive force (Hc), and maximum energy product (BH max).
Neodymium Magnets:
  • Bonded neodymium magnets are highly requested and produced according to customer designs.
  • These magnets are not typically kept in stock, except for limited samples.
Technical Data:
  • Density ranges from 3.5 to 3.7 g/cm3.
  • Operating temperature ranges from -40°C to +100°C.
  • Hardness is between 45 and 50 (D scale).
  • Tensile strength is 50 kg.f/cm2.
  • Reversible temperature coefficient is -0.18%/°C.
Performance Characteristics:
  • Curie temperature and maximum operating temperature are specified for different magnet grades.
  • Magnetic properties such as remanence, coercive force, and maximum energy product are detailed for various neodymium magnet types (e.g., NEOBM-4, NEOBM-6).
