Wholesale powerful strong permanent alnico magnet cylinder magnet
Cast Alnico magnet is composed primarily of Aluminum, Nickel, Cobalt, Copper and Iron. It has very good corrosion resistance and high temperature operation. Although other magnetic materials offer greater energy and coercivity values, the high remanence and thermal stability of AlNiCo makes it the most effective magnetic material for certain applications, like sensors, generator, microphone, lifting, voltmeter and measuring instruments. It is widely applied in high stability fields like aerospace, military, automobile and security systems.
Magnetic Feature

Custom Permanent Magnets for Sensor Applications
Bearheart provides rare earth magnets (Samarium–Cobalt & Neodymium), hard ferrite and AlNiCo permanent magnet, molded magnets for sensor applications. They all come in different sizes and shapes. Meanwhile, they have different magnetic strengths.
Different types of sensors and different working environments require different permanent magnets. Because of magnet’s properties, it should be fully considered a shock, vibration, strong external magnetic fields as well as high temperatures in the design of sensor magnet. All these factors will influence the magnetic force and the long term stability in different ways.
The sintered neodymium magnet is the strongest magnet. The rare earth smco magnets combine high magnetic force and high working temperature. Alnico magnets are the most stable magnet and can work up to 550°C. Ferrite magnets are the cheapest magnet and their coercivity is higher than alnico magnets. Molded magnets are best for the multi-poles requirement and they are customized in various material, shapes and sizes.
