About Magnet

1.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.

About Magnet

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.

2.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.

3.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.

4.AlNiCo Magnet Steel ALNICO5 AlNICO8
Alnico magnets are formed by Aluminium, Nickel and Cobalt,It also contains Iron,Copper, Titanium,Component constitution will Influence magnetismproperties, Alnico magnets are produced by sintered or casted technique, The surfaces need machining grounding to a smoother surface have a brightly metallic looking. Casting AlNiCo magnets have offered more flexibility for variety sizes and shapes, while Sintered AlNiCo magnets have smaller tolorances but their machanical properties are not good.
The most commonly used Alnico is Alnico5. There are 4 sort of cast Alnico5 plus a single sort of sintered Alnico5 ( sintered Alnico and cast Alnico have slightly different magnetism and mechanical performance). Among the permanent magnetic materials, AlNiCo have the best reversible temperature coefficient, the highest working
temperature up to 500 ℃, it has the hardest and toughest strongness.
Most Alnico magnet grades are anisotropic ( axial / vertical direction add magnetization ).others are isotropic(horizontal direction magnetized and have many poles on one magnet) they are weaker on magnetism but offer more options on design and properties.

5.Flexible Rubber Magnet
Flexible Rubber magnets are compound materials made of mixing SrO6 ,Fe2O3 powders and CPE rubber. By extruding , flattening and rolling, the raw materials could easily form into suitable shape and size. Since rubber magnets has good plasticity,It is very convinient to customize colors and sizes.
Due to the special component structure, magnetism of rubber magnets are very low while flexible rubber magnets are very hard to get corrosion or demagnetization.
There are two version of flexible rubber magnets:natual type and isomer type. Natural rubber magnets have weaker magnetism,commonly used on fridge decorating,
presswork and AD domain, isomer rubber magnets have stronger magnetism and widly used in applications as micro-motor and toy.
