The Alnico (Aluminum, Nickel, Cobalt) family was introduced in the 1930\\\'s. It\\\'s characterized by excellent temperature stability, high residual induction, relatively high energies and resistant to corrosion. These were the first materials specifically designed for permanent magnets to be used in meters and instruments commercially. Alnico is vailable in both cast and sintered forms. Sintered Alnico offer slightly lower Magnetic

Hard Ferrite magnets (ceramic magnets), are mainly manufactured by SrO or BaO and Fe2O3. There are two production methods: Dry press and Wet press. The dry process is used for istropic and anistropic material, and the wet method applies only to the production of anistropic material.
The elements of Ferrite magnet are ferric oxide、barium、strontium. Ferrite has higher coercive force and higher resistance to be demagnetized and

NdFeB magnets have very high Magnetic properties. Their (BH)max value is 3 to 10 times higher than sintered ferrite magnets. Hci value is 5 to 10 times higher than sintered ferrite magnets and 5 to 15 times higher than AlNiCo magnets. The potential Magnetic properties of NdFeB magnets are very high. Theoretically, their (BH)max value can be as high as 527 KJ/M3 (66 MGOe).
NdFeB magnets is cheaper than smco. Since the major raw mat

1). Without power; no risk in the condition of no electrical source.
2). Use high-energy permanent magnetic material to be smaller volume.
3). A great concentration of power with a safety factor 1:3.5 on the suggested load.
4). Optimized magnetic circuit together with appearance design made the structure of the product simple and firm, even with a large air gap.
5). Special handle-operating switch with safety bottom.
6)

Rubber magnet is a magnet compounded by magnetic powder and high polymer materials through the special craft. It has some advantages in magnet shaping, size precision, flexibility etc. It may take the strip, circular, various geometric figured, sheet, coiled material (max. width 620mm, thickness0.4-8mm, unlimited length) according to the customer\'s requirements. Its surface may implement UV oil coating, spray lacquer, printing, lami

Samarium Cobalt (SmCo) magnets offer designers a tremendous combination of extremely high Magnetic properties, outstanding thermal stability and excellent corrosion resistance. As part of the rare earth group of permanent magnets, Samarium Cobalt (SmCo) magnets typically fall into two families of materials. They include rare earth SmCo5 and Sm2Co17, and are commonly referred to as 1:5 and 2: 17 materials.
