圆柱型磁铁是目前性能最高的永磁材料之一，随着它的出现而相应出现了许多高科技产品，特别在电机中的应用，使许多产品向小型化、微型化发展。烧结钕铁硼的高剩磁、高矫顽力及高磁能积，使其广泛应用于伺服电机、扁平无刷电机与步进电机、IT产品、核磁共振、扬声器等产品中。由于钕铁硼磁铁容易生锈氧化，所以对其表面通常作电镀处理，如镀锌、镍、银、金等，也可以做磷化处理或喷环氧树脂来减慢其氧化速度。圆柱型磁铁磁性能表牌号剩磁矫顽力内禀矫顽力最大磁能积最大工作温度BrHcbHcj（ BH ） maxmTkGskA/mkOekA/mkOekJ/m3MGOeN271030-108010.3-10.8≥796≥10.0≥955≥12199-23125-2980 ℃N301080-113010.8-11.3≥796≥10.0≥955≥12223-24728-3180 ℃N331130-117011.3-11.7≥836≥10.5≥955≥12247-27131-3480 ℃N351170-122011.7-12.2≥868≥10.9≥955≥12263-28733-3680 ℃N381220-125012.2-12.5≥899≥11.3≥955≥12287-31036-3980 ℃N401250-128012.5-12.8≥907≥11.4≥955≥12302-32638-4180 ℃N421280-132012.8-13.2≥915≥11.5≥955≥12318-34240-4380 ℃N451320-138013.2-13.8≥923≥11.6≥955≥12342-36643-4680 ℃N481380-142013.8-14.2≥923≥11.6≥876≥12366-39046-4980 ℃N501400-145014.0-14.5≥796≥10.0≥876≥11382-40648-5160 ℃N521430-148014.3-14.8≥796≥10.0≥876≥11398-42250-5360 ℃30M1080-113010.8-11.3≥796≥10.0≥1114≥14223-24728-31100 ℃33M1130-117011.3-11.7≥836≥10.5≥1114≥14247-26331-33100 ℃35M1170-122011.7-12.2≥868≥10.9≥1114≥14263-28733-36100 ℃38M1220-125012.2-12.5≥899≥11.3≥1114≥14287-31036-39100 ℃40M1250-128012.5-12.8≥923≥11.6≥1114≥14302-32638-41100 ℃42M1280-132012.8-13.2≥955≥12.0≥1114≥14318-34240-43100 ℃45M1320-138013.2-13.8≥995≥12.5≥1114≥14342-36643-46100 ℃48M1360-143013.6-14.3≥1027≥12.9≥1114≥14366-39046-49100 ℃50M1400-145014.0-14.5≥1033≥13.0≥1114≥14382-40648-51100 ℃30H1080-113010.8-11.3≥796≥10.0≥1353≥17223-24728-31120 ℃33H1130-117011.3-11.7≥836≥10.5≥1353≥17247-27131-34120 ℃35H1170-122011.7-12.2≥868≥10.9≥1353≥17263-28733-36120 ℃38H1220-125012.2-12.5≥899≥11.3≥1353≥17287-31036-39120 ℃40H1250-128012.5-12.8≥923≥11.6≥1353≥17302-32638-41120 ℃42H1280-132012.8-13.2≥955≥12.0≥1353≥17318-34240-43120 ℃45H1300-136013-13.6≥963≥12.1≥1353≥17326-35843-46120 ℃48H1370-143013.7-14.3≥995≥12.5≥1353≥17366-39046-49120 ℃30SH1080-113010.8-11.3≥804≥10.1≥1592≥20223-24728-31150 ℃33SH1130-117011.3-11.7≥844≥10.6≥1592≥20247-27131-34150 ℃35SH1170-122011.7-12.2≥876≥11.0≥1592≥20263-28733-36150 ℃38SH1220-125012.2-12.5≥907≥11.4≥1592≥20287-31036-39150 ℃40SH1240-128012.5-12.8≥939≥11.8≥1592≥20302-32638-41150 ℃42SH1280-132012.8-13.2≥987≥12.4≥1592≥20318-34240-43150 ℃45SH1320-138013.2-13.8≥1003≥12.6≥1592≥20342-36643-46150 ℃28UH1020-108010.2-10.8≥764≥9.6≥1990≥25207-23126-29180 ℃30UH1080-113010.8-11.3≥812≥10.2≥1990≥25223-24728-31180 ℃33UH1130-117011.3-11.7≥852≥10.7≥1990≥25247-27131-34180 ℃35UH1180-122011.8-12.2≥860≥10.8≥1990≥25263-28733-36180 ℃38UH1220-125012.2-12.5≥876≥11.0≥1990≥25287-31036-39180 ℃40UH1240-128012.5-12.8≥899≥11.3≥1990≥25302-32638-41180 ℃28EH1040-109010.4-10.9≥780≥9.8≥2388≥30207-23126-29200 ℃30EH1080-113010.8-11.3≥812≥10.2≥2388≥30223-24728-31200 ℃33EH1130-117011.3-11.7≥836≥10.5≥2388≥30247-27131-34200 ℃35EH1170-122011.7-12.2≥876≥11.0≥2388≥30263-28733-36200 ℃38EH1220-125012.2-12.5≥899≥11.3≥2388≥30287-31036-39200 ℃
