RARE EARTH (NEODYMIUM) MAGNETS Rare Earth (or Neodymium) Magnets are extremely powerful. They are among the strongest of all magnets, and are relatively affordable, making them very popular. They are considered permanent magnets, although some rare earth magnets will lose their magnetic field at high temperatures. Some are also quite brittle unfortunately, which means that they need to be used with care, as they can break apart with explosive force. Produced by the powder metallurgical method with chemical composition of Nd2Fe14B Very hard and brittle – cannot be drilled or machined Extremely stable and highly resistant to demagnetisation. Low resistance to corrosion High resistance to magnetic demagnetization Excellent cost to performance ratio Not suitable for applications which are exposed to high temperatures - up to 80˚ RARE EARTH DISC MAGNETS: Part No. Diameter Height ND3002 ND3004 ND4002 ND6002 ND6006 ND6010 ND6012 ND6014 ND7002 ND9004 ND9006 ND1002 ND1004 ND1202 ND1204 ND1206 ND1208 ND1214 ND1508 ND2004 ND2202 ND2504 ND2508 ND3020 ND3022 ND5004 ND7502 ND101.6 Dimensions Description 3mm dia x 1.5mm 3mm dia x 10mm 4.75mm dia x 1.5mm 6mm dia x 1.5mm 6mm dia x 6mm 6.35mm dia x 5.08mm 6.35mm dia x 6.35mm 6.35mm dia x 12.7mm 7mm dia x 3mm 9.5mm dia x 6.35mm 9.5mm dia x 10mm 10mm dia x 1.5mm 10mm dia x 3mm 12mm dia x 1.5mm 12mm dia x 5mm 12mm dia x 6.6mm 12mm dia x 10mm 12.7mm dia x 12.7mm 15mm dia x 7mm 20mm dia x 10mm 22mm dia x 10mm 25mm dia x 5mm 25mm dia x 12.7mm 30mm dia x 5mm 30mm dia x 10mm 50mm dia x 12.5mm 75mm dia x 15mm 101.6mm dia x 25.4mm Pull Force 300gm 1.8Kg 500gm 500gm 2.2Kg 2Kg 2.4Kg 4.9Kg 1Kg 4Kg 5.6Kg 1Kg 2Kg 2.3Kg 4Kg 5Kg 8Kg 9.8Kg 6Kg 12Kg 13Kg 8Kg 19Kg 9Kg 18Kg 39Kg 69Kg 157Kg Diamater x Height (thickness) _____________________________________________________________________________________________________ GHE LIFTING SPECIALIST AUGUST 2013 1|P age RARE EARTH RING MAGNETS: Part No. NR1902 NR2002 NR2004 NR3002 NRCS2502 Dimensions Description 19mmOD x 8mmID x 4mm 20mmOD x 4mmID x 12.7mm 20mmOD x 10mmID x 8mm 30mmOD x 15.5mmID x 8mm 25mmOD x 6mmcsk x 10mm Pull Force 4.3Kg 2.7Kg 7.3Kg 9.5Kg 14.9Kg Outside Diamater x Inside Diameter x Height (thickness) Outside Diameter Height Inside Diameter Rare Earth (or Neodymium) Pot Magnets are high strength rare earth magnets in a mild steel cap for extra protection against chipping or cracking. Due to the protective cover, they are a single sided magnet which allows for a non-destructive and easy solution for a wide range of uses. _____________________________________________________________________________________________________ GHE LIFTING SPECIALIST AUGUST 2013 2|P age RARE EARTH POT MAGNETS: Rare Earth Pot Magnet with post and hook Part No. NP2502PH NP3602PH NP4202PH NP4802PH NP6002PH Pull Force Description 25mm pot - threaded post/ hook 36mm pot - threaded post/ hook 42mm pot - threaded post/ hook 48mm pot - threaded post/ hook 60mm pot - threaded post/ hook 22Kg 41Kg 68Kg 81Kg 113Kg Part No. Dia - D Dia - M H h Pull Force NP2502PH NP3602PH NP4202PH NP4802PH NP6002PH 25 36 42 48 60 5 6 6 8 8 15 16 16 23 23 8 8 9 11.5 15 22 41 68 81 113 (Kg) Weight (gm) 37 68 97 154 282 Rare Earth Pot Magnet with male thread Part No. NP3602MT NP6002MT Pull Force Description 36mm pot – male thread 60mm pot – male thread 41Kg 113Kg Part No. Dia Dia - M H h Pull Force NP3602MT NP6002MT 36 60 6 8 18 30 8 15 41 113 (Kg) Weight (gm) 57 254 _____________________________________________________________________________________________________ GHE LIFTING SPECIALIST AUGUST 2013 3|P age Rare Earth Pot Magnet with countersunk centre Part No. NP16CSK NP20CSK NP25CSK NP32CSK NP42CSK NP48CSK Part No. Pull Force Description 16mm pot - countersunk 20mm pot - countersunk 25mm pot - countersunk 32mm pot - countersunk 42mm pot - countersunk 48mm pot - countersunk 5Kg 6Kg 14Kg 25Kg 37Kg 68Kg Dia - D Dia - D1 Dia–D2 H Holding Force 16 20 25 32 42 48 3.5 4.5 5.5 5.5 6.5 8.5 6.5 8.5 10.4 10.4 12 16 5 7 8 8 9 11.5 5 6 14 25 37 68 NP16CSK NP20CSK NP25CSK NP32CSK NP42CSK NP48CSK (Kg) Weight (gm) 7 13 23 39 76 120 RARE EARTH BLOCK MAGNETS: Length Part No. NB6002 NB1202 NB2502 NB2508 NB5000 NB5002 NB5004 NB7004 Description 6.35mm x 6.35mm x 2.5mm 12.5mm x 6mm x 3mm 25mm x 9mm x 3mm 25mm x 25mm x 5mm 50mm x 25mm x 12.7mm 50mm x 50mm x 12.5mm 50mm x 50mm x 25.4mm 70mm x 70mm x 12.7mm Dimensions Length x Width x Height (thickness) Pull Force 1.1Kg 1.7Kg 3.1Kg 8.7Kg 30.8Kg 42.9Kg 85.8Kg 61.3Kg Width Height _____________________________________________________________________________________________________ GHE LIFTING SPECIALIST AUGUST 2013 4|P age CERAMIC (FERRITE) MAGNETS Ceramic (or Ferrite) Magnets are very hard and brittle. With a grey natural finish, Ceramic Magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. They provide less energy than Rare Earth Magnets, have a high resistance to demagnetisation, are more resistant to corrosion and are very low cost. As with Rare Earth Magnets, they need to be used with care, and can break apart with explosive force. Produced by the powder metallurgical method with chemical composition of Ba/Sr O.6 Fe2O3 Very hard and brittle – cannot be drilled or machined Good resistance to demagnetisation.
