Dongyang Aviation Magnetic Ltd is one of the leading China special shaped magnet manufacturers and suppliers,Website:http://www.zjmagnet.com, welcome to wholesale or buy donut magnets, lifting magnets, pie magnet, cylindrical magnets, horseshoe magnet from our factory. Ferrite divided barium ferrite (BaO 繚 6Fe2O3) and strontium ferrite (SrO 繚 6Fe2O3). High resistivity, is a semiconductor type, so a small eddy current losses, the coercive force, not the merits of demagnetization can be effectively applied in the air gap in the magnetic circuit, particularly suitable for small generators and permanent magnet motors. The major products anisotropic ferrite permanent magnet series. They can be used to make the permanent ignition motors, permanent magnet motors, permanent magnet concentrator, magnetic lifting heads, magnetic thrust bearing, magnetic separator, speakers, microwave devices, magnetic sheet, and hearing aids.Sintered Ferrite Magnet Performance and Grade Grade (Br) (HcB) (HcJ) (BH)max mT KGauss KA/m KOe KA/m KOe KJ/m3 MGOe Y10T 200~235 2.0~2.35 125-160 1.57-2.01 210-280 2.64-3.51 6.5-9.5 0.8-1.2 Y22H 310~360 3.10~3.60 220-250 2.76-3.14 280-320 3.51-4.02 20.0-24.0 2.5-3.0 Y25 360~400 3.60~4.00 135-170 1.70-2.14 140-200 1.76-2.51 22.5-28.0 2.8-3.5 Y26H-1 360~390 3.60~3.90 200-250 2.51-3.14 225-255 2.83-3.20 23.0-28.0 2.9-3.5 Y26H-2 360~380 3.60~3.80 263-288 3.30-3.62 318-350 3.99-4.40 24.0-28.0 3.0-3.5 Y27H 350~380 3.50~3.80 225-240 2.83-3.01 235-260 2.95-3.27 25.0-29.0 3.1-3.6 Y28 370~400 3.70~4.00 175-210 2.20-3.64 180-220 2.26-2.76 26.0-30.0 3.3-3.8 Y28H-1 380~400 3.80~4.00 240-260 3.01-3.27 250-280 3.14-3.52 27.0-30.0 3.4-3.8 Y28H-2 360~380 3.60~3.80 271-295 3.40-3.70 382-405 4.80-5.08 26.0-30.0 3.3-3.8 Y30H-1 380~400 3.80~4.00 230-275 2.89-3.46 235-290 2.95-3.64 27.0-32.5 3.4-4.1 Y30H-2 395~415 3.95~4.15 275-300 3.45-3.77 310-335 3.89-4.20 27.0-32.0 3.4-4.0 Y32 400~420 4.00~4.20 160-190 2.01-2.39 165-195 2.07-2.45 30.0-33.5 3.8-4.2 Y32H-1 400~420 4.00~4.20 190-230 2.39-2.89 230-250 2.89-3.14 31.5-35.0 3.9-4.4 Y32H-2 400~440 4.00~4.40 224-240 2.81-3.01 230-250 2.89-3.14 31.0-34.0 3.9-4.3 Y33 410~430 4.10~4.30 220-250 2.76-3.14 225-255 2.83-3.20 31.5-35.0 3.9-4.4 Y33H 410~430 4.10~4.30 250-270 3.14-3.39 250-275 3.14-3.45 31.5-35.0 3.9-4.4 Y34 420~440 4.20~4.40 200-230 2.51-2.89 205-235 2.57-2.95 32.5-36.0 4.1-4.4 Y35 430~450 4.30~4.50 215-239 2.70-3.00 217-241 2.73-3.03 33.1-38.2 4.1-4.8 Y36 430~450 4.30~4.50 247-271 3.10-3.40 250-274 3.14-3.44 35.1-38.3 4.4-4.8 Y38 440~460 4.40~4.60 285-305 3.58-3.83 294-310 3.69-3.89 36.6-40.6 4.6-5.1 Y40 440~460 4.40~4.60 330-354 4.15-4.45 340-360 4.27-4.52 37.6-41.8 4.7-5.2
