Factory best selling Alnico Pickup Magnets - Alnico Permanent Manget Rare Earth Magnet – Xinfeng Detail:
PRODUCT INTRODUCTION
Alnico Magnet is the alloy magnet of Aluminum, Nickel, Cobalt, Iron and other trace metal elements, which is the first generation of permanent magnet materials that developed at the earliest.
Alnico Permanent Magnet materials have the advantage of high Br (up to 1.5T) and low temperature coefficient, stable magnetic, high temperature resistance, moisture resistance and oxidation resistance. When the temperature coefficient is -0.02%/℃, the maximum operating temperature can reach 550℃. The disadvantage is that the coercivity is very low and the demagnetization curve is nonlinear. Therefore, although Alnico magnets are easily magnetized, they are also easy to demagnetize.
According to the production process, it can be divided into Sintered Alnico and Cast Alnico. The shape of the product is mostly round and square. Casting process can be processed into different sizes and shapes;
Compared with the casting process, the sintered product is limited to small size products. The dimensional tolerance of sintered blanks is better than that of the cast product while the magnetic properties are slightly lower than that of the cast product
Alnico is now widely used in magnetoelectric instruments, electromagnetic flowmeters, relays, teaching instruments, electric guitar pickups, microphones, sensors, traveling wave tubes, cow magnets and other fields.
