what is the magnets

Sintered NdFeB Magnet, the most advanced permanent magnet, are made from Neodymium Iron Boron by sintered processing. This magnet has the highest energy products, so it is widely used in miniature products and automatical components. Normally, NdFeB magnets are to be coated with Nickle, Zinc and Epoxy, or just anti-rusty treatment to protect its appearance for corrosion resistance. For the time being, the NdFeB magnets are the most popular one in magnetic materials, we forecast that this advanced material may last 15 years in the days to come continuously.

The Bonded NdFeB Magnet is produced by mixing the ferrite powder and rare earth powder with resin, and is formed by either mold compression or injection. Without magnetic field while compression, it is available to be formed into a wide range of shapes. However, tooling is always needed, no matter what the production way be taken. In addition, when taking compression, the dimension can be controlled in a very precise level, which make the engineers easily to device a light and miniature Hi-performance products. Besides, this magnet normally be coated with epoxy or others appearance treatments which make the product anti-corrosion. The bonded NdFeB magnet is one kind of Isotropic magnet, which can be magnetized with axially or radially respectively.

Ferrite Magnet including "Isotropic" and "Anisotropic" are sintered magnet with either by dry pressed or wet pressed. Tooling is always needed when pressed. The magnetization can be done by axially, radially, multi-poles axially and multi-poles on circumference, etc. Due to the low cost, medium power and productivity by mass production, they are widely used in various industries for many different applications. We can say that the Ferrite magnets were the most popular one in magnetic materials for past 30 years.

High quality Anisotropic Ferrite Magnet made by cutting.
The main material of the Cutting Magnet is the strontium ferrite magnet, that is made by wet press. Basically, the density in wet press is better than the dry press, so the cutting magnets can achieve a good performance even just a small dimension. The largest of block size for cutting magnet is L220 x W150 x 25.4mmT, and the most common one is L152 x W100 x 25.4mmt(6" x 4" x1"). Presently, the smallest size that we are able to make is L2 x W2 x T0.8mm.

The Alnico Magnet contains the elements of Aluminum, Cobalt and Nickle Alloy, which can be made either by casting or sintering process. As having the features of both hardness and high working temperature parameters, they are widely used in many different application with a wide range of magnetic properties. Meantime, an excellent corrosion resistance is also one of its features. However, the most disadvantageous point for this material is in low value of coercive force, which be possible to decrease the magnetic power during in use subject to using environment, we suggest you to discuss with us when ordering.

By using iron cap, iron plate or iron yoke with the magnets, Magnetic pot magnet Assembly would be getting more loading power, even up to several kilograms. The magnets material can be used by Ferrite、NdFeB、Alnico or Rubber, etc. Besides, the products surface also can be planted by Ni, Zn, Chrome or Black plating for customer choice. The Magnetic Applications and Magnetic Holders are widely used for DIY Parts, Hardware, Auto Parts, Machinery Industry, IC Industry, IT Industry and Filter, etc.

Flexible Rubber Magnet are made of ferrite magnet powder or rare earth powder, compound with rubber, resin and other materials. Formed by extruding, injecting or calendering, the rubber magnets have different shapes such as strip, sheet or roll. Since the rubber magnet is plasticity, it can be made with any shapes by pressing or cutting. Besides, it is also very flexible, so it can be coiled to 1/4" radius without breaking. There are "Isotropic" and "Anisotropic" in the flexible rubber magnet. The Isotropic rubber magnet normally is to be magnetized with multipoles magnetization on one side only and the Anisotorpic one has magnetics on both side. Based on customer's demand, the rubber magnets can be laminated by colorful PVC, adhesive tape or colorful printing. The attractive face is treated with UV coating which can protect the products surface. We also can supply. Magnetic Paper " for A4 size, which made from rubber magnets and laser paper. The thickness just has 0.3mm which can be printed by any printing machine!

Rubber magnets are made of a permanent flexible magnetic material which is available in sheet, strip, and extrusion forms, which can further be given various shapes like ring, square, segment, cylinder and other shapes.

Types of rubber magnets

Isotropic magnets: These are widely used for daily necessary industryand seen in toys, family education, printing and decoration etc.

Anisotropic magnets: These rubber magnets are made by extrusion or injection. Properties like high elasticity, flexibility and machine ability make these magnets a favorite choice for many permanent magnet applications in industry and in home appliances.

Uses and Applications of Rubber Magnets: Rubber magnets  provide an alternative material  for printing,  holding, signage, and  fastening applications.  Designers, printers, marketers, salespeople, engineers, teachers, manufacturers, sign makers, material-handling specialists  etc. all use rubber magnets.  These magnets  are  ideal for applications where a low cost magnet needs to be combined with complex form precisely. These magnets are used in food industry, advertising industry, factory equipment industry, office and home etc.
