Cast alnico magnets have high magnetic flux density (Br) and superior heat resistance and temperature characteristics and are used in a wide range of applications.
While sintered alnico magnets have magnetic properties equivalent to cast magnets, they can achieve good finishing surfaces and dimension accuracy without polishing even for uses that require small or complex shapes.
It can also achieve uniformity for products when high-volumes are demanded.

Among metallic magnets, iron, chrome, and cobalt magnets (FCC magnets) have a higher magnetic flux density (Br) and energy product than alnico magnets. In particular, their properties are superior to alnico semi-columnar crystal (5DG) magnets. Their superior workability makes them well suited to cutting, boring, rolling, punching, etc.

When compared to the rare-earth Nd-Fe-B magnets, they have superior heat resistance, temperature characteristics, and corrosion resistance.
Therefore, they can be used without a special rust-proof treatment even in high-temperature or highly corrosive environments.
In addition, using them does not involve any patent issues, so you can use them with peace of mind.
