Alnico Ring Magnet Alnico II
Alnico ring magnet is a common shape magnet we can see in lots of magnets designed for applications like sensors, meters, or some other magnetic applications.
This Alnico Ring Magnet is an Alnico 2 magnet, it is one grade of the Alnico magnet material, they can be separated to Alnico 1, 2,3,5, and even 8 and 8H, etc.
The Alnico is the second weak magnetic force in the Alnico magnet grades, they don’t have a strong magnetic performance, but a lower coercive force that can have some special applications to magnetized and demagnetized easily with the designed applications. And the Alnico 2 is a type of isotropic material that can be magnetized in any direction, that also supplies some special functions as requested.
Alnico Ring Magnet Manufacturing
The Alnico Ring Magnet can be produced by the process of sintering and casting, usually, the small size Alnico ring magnet is produced by the sintering process. The sintering processes produced the magnet with a technology named Powder metallurgy. The materials all will be powder to a certain powder size and mixed at a certain rate, then press them to the shape. Then sintered them in a sintering furnace at a very high temperature. and different from the Neodymium magnet, the sintered Alnico magnet will have an independent heat treatment process to make the magnetic properties. Then with some machining processes like grinding.
