Typical Magnetic properties of Flexible rubber magnet, Rubber Magnets

Flexible Rubber magnets are compound materials made by mixing ferrite magnet powder and rubber. Pressing or rolling makes the finished flexible rubber magnet. Because the material has good plasticity, the finished flexible rubber magnets or semi-manufactured flexible rubber magnets can incise, stiletto, slit or back up other materials randomly, have good antisepsis and difficult demagnetization. The raw materials are plentiful, so the price is lower. Flexible Rubber magnets are natural Flexible Rubber magnets or isomer Flexible Rubber magnets. Natural rubber magnets have weak magnetism, are used on iceboxes, presswork and marketing and promotion premiums. Isomer rubber magnets have strong magnetism, and are used in such applications as micro-motors and magnet toys.

Magnetic Properties of Sintered AlNiCo Magnet

AINiCo magnet is an alloy of aluminum-nickel-cobalt, has excellent temperature stability and corrosion resistance, it can be used in motor, sensor, separator, loudspeaker and holding system. This class of magnet remains a preferred material because of it’s excellent temperature stability, high magnetic flux density, and resistance to corrosion. Alnico magnets are manufactured through a casting or sintering process. The casting process allows for the magnet to be manufactured into intricate and complex shapes, which are not possible with other magnetic materials.
