Alnico Bar Magnets
Alnico bar magnets
Alnico bar magnets are composed of an alloy including aluminum, nickel, cobalt, and iron, characteristics that confer them with excellent temperature stability and a high resistance to demagnetization. These magnets are especially notable for their ability to function effectively at high temperatures, up to 550 degrees Celsius. Alnico bar magnets are typically manufactured through casting or sintering processes, with casting providing stronger magnetic properties.
Their rectangular bar shape makes them versatile for a variety of applications. These include educational tools for demonstrating magnetic principles, as well as essential components in sensors, electric motors, and precision instruments where consistent performance across a broad temperature range is critical. The bright metallic appearance and robust physical properties of alnico bar magnets also make them suitable for use in artistic and design projects.
Despite the advent of more powerful rare earth magnets, alnico bar magnets remain popular due to their reliable performance in high heat and other demanding environments, showcasing their enduring relevance in both industrial and educational settings.
