Alnico block magnets
Alnico block magnets are crafted from an alloy of aluminum, nickel, cobalt, and iron, forming a robust magnet known for its excellent thermal stability and resistance to demagnetization. These magnets can withstand temperatures up to 550 degrees Celsius, making them suitable for high-temperature environments. Alnico block magnets are generally produced through casting or sintering, with the casting process yielding magnets with superior magnetic properties.
Their block shape allows for a wide range of applications across various industries. Alnico block magnets are frequently used in sensors, electric motors, and holding applications, where their strong magnetic field and durability are crucial. They are also favored in educational contexts for demonstrations due to their clear and strong magnetic properties.
Despite newer materials offering higher magnetic strengths, alnico block magnets are valued for their reliability and consistent performance under thermal stress, making them a preferred choice in applications requiring a stable magnetic field at elevated temperatures. Their traditional uses continue to make them indispensable in many engineering and design fields.
