According to different production processes, there are Sintered AlNiCo and Cast AlNiCo. Most of the products are round and square in shape. The casting process can be processed and produced into different sizes and shapes; compared with the casting process, the sintered products are limited to small sizes, and the dimensional tolerances of the produced blanks are better than those of the cast products, and the magnetic properties are slightly lower than those of the cast products, but the processability is better. Among the permanent magnet materials, cast Alnico permanent magnets to have the lowest reversible temperature coefficient and can work at temperatures up to 600 degrees Celsius or more. Alnico permanent magnets are widely used in various instrumentation and other applications.
The advantages of Alnico magnets are high reminisce (up to 1.35T) and low-temperature coefficient. At a temperature coefficient of -0.02%/°C, the maximum operating temperature can be around 520°C. The disadvantages are very low coactivity (usually less than 160kA/m) and a non-linear demagnetization curve. Therefore, although Alnico magnets are easily magnetized, they are also easily demagnetized.
Circular shaped alnico magnet.
Powerful bar shaped alnico magnet for your choices, it also calls alnico magnet rod.
Special shaped ''V'', or ''horseshoe'' alnico magnet for many uses, it also call alnico guitar magnet.
