1 At present, the price of Smco magnet is in low point, which is a good time to purchase. This magnet is very brittle, So the magnetized SmCo must be picked up carefully and gently during the assemble process and kept away from ironware to avoid mutually attracting, causing chips and cracks or other damage to magnet's surface. Cobalt is an essential component of Samarium Cobalt magnets (SmCo).

2. AlNiCo magnet can be magnetized in two different ways, isotropic or anisotropic. With high operating temperatures, it is popular choice for aerospace, automotive and military application, exactly it can also be used in guitar pick-ups, sensors, electric motors, bearing, heat treatment Jigs and recovery and so on. They don’t corrode even it was exposed to motor oil, petrol, solvents and alcohol. So it is not need to do coating.  as time goes on, the AlNiCo magnet may be corroded if it exposed to water because of small amounts of iron attached.

3. Ferrite is a ceramic material with iron oxide as its main component. Most ferrites are magnetic materials used to make Permanent magnets, transformer cores, and other related applications. They are low cost, can work in +250 degree C, particularly in high volume production runs. It has “pencil lead” appearance. Ferrite has become a non-metallic magnetic material with a wide range of applications in the field of high frequency and low voltage. Since the magnetic energy stored in the unit volume of ferrite is low, thus limiting its applications in the field of high voltage and high power.
