A rubber magnet is a magnet made from rubber and magnetic material. Ceramic or rare earth magnets may be used as magnetic materials, which are typically made from materials such ferrite or neodymium. Product types include sheet-shaped types and band-shaped types.

Rubber-coated magnets are small neodymium magnets placed on a steel plate and then encapsulated in a rubber-coated housing. We use high-quality TPV or EPDM rubber coating material because it has excellent physical and chemical properties. Rubber-coated magnets can help protect neodymium magnets from debris and corrosion.

The rubber coating also protects the magnets from cracking and corrosion. In addition, it is also very slip-resistant due to the friction between the rubber and the magnet-bonded steel surface. So its application is very extensive. Manufacturers and industrial designers use rubber-coated magnets for fixation. They are also ideal for aquariums, construction sites and outdoor use.

Ferrite is divided into isotropic and anisotropic types. Isotropic magnets can be magnetized in any direction because they have no orientation, while anisotropic magnets are oriented along the manufacturing direction and need to be magnetized along the orientation direction. The magnetic property of anisotropic magnets is stronger than that of isotropic ones. Common performance types of anisotropic magnets are Y25, Y30, Y35, Y30BH, etc.; common performance types of isotropic magnets are Y8T, Y10T.

SmCo permanent magnet is a superior permanent magnetic material. It has very high magnetic properties, strong corrosion resistance, high antioxidant property, low temperature coefficient, high Curie temperature, and can be used in relatively high – temperature environments. SmCo permanent magnets are widely used in motors, instruments, sensors, detectors, radars, and other high – tech fields.

SmCo5 magnets’ (BH)max values is regular between 14 and 24MGOe. SmCo5 is made of only Samarium and Cobalt and exhibit better corrosion resistance and machinability.
Sm2Co17 magnets’ (BH)max values is conventional between 22 and 32MGOe which much higher than the former SmCo5 series. Besides two basic elements Samarium and Cobalt, different grade of Sm2Co17 varies in the content of Iron (Fe), Copper (Cu), Zirconium (Zr).

According to product categories, it is mainly divided into cast AlNiCo and sintered AlNiCo. Cast AlNiCo is mainly used in automotive parts, instrumentation electro-acoustics, motors, nuclear power, teaching, aerospace, and other fields. It has the characteristics of low temperature coefficient, high – temperature resistance, moisture – resistance, not easy to oxidize, and good working stability. Sintered AlNiCo is produced by the powder metallurgy method and is suitable for producing complex, light, thin, and small products. It is widely used in instruments, communications, magnetic – electric switches, and various sensors.

Cast magnet is larger in density which provides it better magnetic performance. Casting process also well-suited to large and complex shapes.

Sintered magnet exhibit slighter lower magnetic performance but better mechanical properties.

SmFeN is a new – generation rare – earth permanent magnetic material following NdFeB magnets. It has excellent magnetic properties and corrosion resistance and is suitable for making high – performance bonded magnets. Samarium – iron – nitrogen bonded magnets have the advantages of flexibility and size flexibility and are very suitable for applications of strong magnetic materials that require custom – sized or complex – shaped magnets, such as sensors, motors, generators, etc.

Samarium – iron – nitrogen bonded magnets are increasingly being used in various industries such as automobiles, electronic products, medical devices, and renewable energy.

Fe-based nanocrystaline is an iron-based soft magnetic alloy material prepared by ultra-rapid cooling solidification technology with a cooling rate of about10*’c/s,12-27um thickness and 1-60mm width. Compared with traditional materials, Fe-based nanocrytaline has excellent metal characteristics such as high saturation magnetic induction, high permeability and low loss, it can replace silicon steel, perm alloy and ferrite as ideal material for components such as medium and high frequency power transformer, current transformer common mode choke.

Fe-based amorphous ribbon is a new soft magnetic alloy material that is mainly composed of iron, silicon, boron and other elements. Its preparation processes are, different from traditional metallurgy process that the ribbon is made from liquid steel in just one step by eliminating traditional metallurgy process of casting, forging, intermediate annealing, rolling and others. The Fe-based amorphous ribbon has obvious benefits of energy saving, environment protection and high production efficiency.
