Rare Earth Magnetic Material Round Shape Neodimium Magnet N52¹

Product Description Rare Earth Magnetic Material Round Shape Neodimium Magnet N52Company ProfileSDM Magnetics Co., Ltd. is a leading Chinese manufacturer of high quality permanent magnet and magnetic assemblies since 2014. SDM serves a variety of markets include automotive, industrial automation, consumer electronics, green energy, household appliances, and aerospace. To meet the more and more demanding markets, SDM has been concentrating on manufacturing technologies for quality stability and cost reduction. With grain boundary diffusion technology, SDM can offer competitive prices for high coercivity Neodymium magnets. SDM has also built up a strategic cooperation with China's No.1 rare earth miner CHINALCO, which gives us strong and safe backup for rare earth raw materials.Product DescriptionNeodymium magnets are a combination of Neodymium, Iron, and Boron which extremely strong for their size. Cylinder magnet is also referred to as Neodymium rod magnet. It is similar with Neodymium disc magnet that Neodymium cylinder magnet is measured according to the diameter (D) and length (L), where the length is equal to or exceeds the diameter. The higher L/D ratio enables the axially magnetized Neodymium cylinder magnets have higher gauss value and making it well suitable for activating hall sensor and reed switch. In addition, Neodymium cylinder magnet with higher L/D ratio can also generate much stronger pull force from the relatively small magnetic pole area and exhibit superior temperature stability. Other representative application of Neodymium cylinder magnet includes magnetic bead separation rack and some holding applications.Typical Coatings & Shapes of Neodymium Magnet Magnetic Properties of Sintered Neodymium MagnetSintered NdFeB MagnetGradeResidual Induction  (Br)Coercive Force (Hcb)Intrinsic Coercive Force (Hcj)Max Energy Product (BH)maxMax Working Temp.TkGskA/mkOekA/mkOeKj/m3MGOe(°C)N351.17-1.2211.7-12.2≥868≥10.9≥955≥12263-28733-3680N381.22-1.2512.2-12.5≥899≥11.3≥955≥12287-31036-3980N401.25-1.2812.5-12.8≥907≥11.4≥955≥12302-32638-4180N421.28-1.3212.8-13.2≥915≥11.5≥955≥12318-34240-4380N451.32-1.3813.2-13.8≥923≥11.6≥955≥12342-36643-4680N481.38-1.4213.8-14.2≥923≥11.6≥955≥12366-39046-4980N501.40-1.4514.0-14.5≥796≥10≥876≥11374-40647-5160N521.43-1.4814.3-14.8≥796≥10≥876≥11390-42249-5360N35M1.17-1.2211.7-12.2≥868≥10.9≥1114≥14263-28733-36100N38M1.22-1.2512.2-12.5≥899≥11.3≥1114≥14287-31036-39100N40M1.25-1.2812.5-12.8≥923≥11.6≥1114≥14302-32638-41100N42M1.28-1.3212.8-13.2≥955≥12≥1114≥14318-34240-43100N45M1.32-1.3813.2-13.8≥955≥12.5≥1114≥14342-36643-46100N48M1.37-1.4313.7-14.3≥1027≥12.9≥1114≥14366-39046-49100N50M1.40-1.4514.0-14.5≥1033≥13≥1114≥14382-40648-51100N35H1.17-1.2211.7-12.2≥868≥10.9≥1353≥17263-28733-36120N38H1.22-1.2512.2-12.5≥899≥11.3≥1353≥ 17287-31036-39120N40H1.25-1.2812.5-12.8≥923≥11.6≥1353≥17302-32638-41120N42H1.28-1.3212.8-13.2≥955≥12≥1353≥17318-34240-43120N45H1.32-1.3613.2-13.6≥963≥12.1≥1353≥ 17326-35843-46120N48H1.37-1.4313.7-14.3≥995≥12.5≥1353≥17366-39046-49120N35SH1.17-1.2211.7-12.2≥876≥11≥1592≥20263-28733-36150N38SH1.22-1.2512.2-12.5≥907≥11.4≥1592≥20287-31036-39150N40SH1.25-1.2812.5-12.8≥939≥11.8≥1592≥20302-32638-41150N42SH1.28-1.3212.8-13.2≥987≥12.4≥1592≥20318-34240-43150N45SH1.32-1.3813.2-13.8≥1003≥12.6≥1592≥20342-36643-46150N28UH1.04-10810.4-10.8≥764≥9.6≥1990≥25207-23126-29180N30UH1.08-1.1310.8-11.3≥812≥10.2≥1990≥25223-24728-31180N33UH1.13-1.1711.3-11.7≥852≥10.7≥1990≥25247-27131-34180N35UH1.17-1.2211.7-12.2≥860≥10.8≥1990≥25263-28733-36180N38UH1.22-1.2512.2-12.5≥876≥11≥1990≥25287-31036-39180N40UH1.25-1.2812.5-12.8≥899≥11.3≥1990≥25302-32638-41180N42UH1.28-1.3212.8-13.2≥899≥11.3≥1990≥25318-34240-43180N28EH1.04-1.0810.4-10.8≥780≥9.8≥2388≥30207-23126-29200N30EH1.08-1.1310.8-11.3≥812≥10.2≥2388≥30223-24728-31200N33EH1.13-1.1711.3-11.7≥836≥10.5≥2388≥30247-27131-34200N35EH1.17-1.2211.7-12.2≥876≥11≥2388≥30263-28733-36200N38EH1.22-1.2512.2-12.5≥899≥11.3≥2388≥30287-31036-39200N40EH1.25-1.2812.5-12.8≥899≥11.3≥2388≥30302-32638-41200N28AH1.04-1.0810.4-10.8≥787≥9.9≥2624≥33207-23126-29230N30AH1.08-1.1310.8-11.3≥819≥10.3≥2624≥33223-24728-31230N33AH1.13-1.1711.3-11.7≥843≥10.6≥2624≥33247-27131-34230N35AH1.17-1.2211.7-12.2≥876≥11≥2624≥33263-28733-36230N38AH1.22-1.2512.2-12.5≥899≥11.3≥2624≥33287-31036-39230Manufacturing Process of Sintered Neodymium Magnet  Magnetization Direction Of Arc MagnetAbout UsFAQ1:How long will you give me the reply?we will contact you in 12 hours as soon as we can.2:Could I get samples?Yes,we have materials in stock to help you to get the samples as soon as we can.3:How about the quality of the magnets?We have the certification of ISO,TS and ROSH,we could send the certification test of our company to you.4:How is the price?As we believe the quality is the most important,we will provide the best quality magnet we can with reasonable price.5:Could you provide me the shortest lead time?We have materials in our stock,if you really need,you can tell us and we will try our best to satisfy you.6:Could I visit your factory?Of course,if you need we will help you to visit our factory.7:If I have paid,when will you help me to produce?When we have received the money in our account,we will give you the receipt and arrange to produce immediately.
