Laboratory High Qualified Magnetic Magnets Stirring Magnetic Stir Bar

According to different production processes, AlNiCo is divided into sintered AlNiCo (Sintered AlNiCo) and Cast AlNiCo (Cast AlNiCo). The product shapes are mostly round and square. The casting process can be processed into different sizes and shapes; compared with the casting process, the sintered product is limited to small sizes, and the produced blank has better dimensional tolerances than the cast product blank, and the magnetic properties are slightly lower than the cast product, but it can Workability is better. Among the magnetic materials, the working temperature of cast AlNiCo can reach 600 degrees Celsius. Alnico permanent magnet products are used in various instruments and other applications. The advantages of AlNiCo magnets are high remanence (up to 1.35T) and low temperature coefficient. The temperature coefficient is -0.02%/℃, and the operating temperature can reach about 520℃. The disadvantage is that the coercivity is low (usually less than 160kA/m) and the demagnetization curve is nonlinear. Therefore, although AlNiCo magnets are easily magnetized, they are also easily demagnetized.
