Neodymium Magnets Permanent NdFeB

Neodymium magnet is a sort of alloy called Nd2Fe14B or NdFeB that formed by Nd,Fe,B,and some transform material like Dy, Ga and Pr. In order to meet different industrialor domestic needs,various of magnet formulas and manufacturing methods have been discovered and applied in past 30 years.The super magnetism of Sintered NdFeB ( N52 is up to 52MGOE ) and moderate price ( half of SmCo magnets ) hence NdFeB magnets have became the best commercialmagnets and widely applied in civil , industrial ,telecommunication and medical areas.Due to the particularity of manufacturing technique, bonded isotropic NdFeB can easily mound into different shapes, the BHmax is up to 10 MGOE, only 20% of sintered type.The magnetism of NdFeB magnet is 40%-70% higher than SmCo magnets, while price is half cheaper,When working temperature is over 220℃ SmCo is better than NdFeB on magnetic stablity and temperature coefficiency.NdFeB magnets are usually axial direction magnetized or dia direction magnetized in magnetizing envioronment from 1 mgoe -100 mgoe it is pending on customers` actual requirement.

Samarium Colablt Magnets SmCo5 Sm2Co17

Samarium Cobalt magnets are divided into 2 sort, SmCo5 & Sm2Co17, magnetization from axial direction or dia direction are both available,compared with SmCo5,
Sm2Co17 magnets have reduced expensive samarium and have rose the magnetic properties.Working temperature of SmCo magnets is up to 350℃.In high temperature situations SmCo magnets are better than NdFeB magnets on magnetism stability and BH use ratio hence they have widely been applied as AC servo motors, operators, industrial motors,sensor, and also applied in aerospace and military areas.

Ceramic Magnets Hard Ferrite Soft Ferrite

Commonly, Hard Ferrite are compund by ceramic Fe2O3,BaCO3 or SrCo3 powders.Soft ferrite magnets are compunded by Fe2O4,Zinc,Nickel and Manganess.The density of ferrite magnets about 5g/cm3,They are electrically nonconductive and ferrimagnetic. Hard ferrites have higher coercivity and higher remanence after magnetization. Ferrite magnets are cheap and widely applied in house hold appliance like horse shoe shaped magnets, metric motors, loud speakers, earphones .Soft ferrite magnets have been extensively used in the cores of RF tranformers , inductors, magnetic recorders.
