Alnico Magnets: High-Heat, High-Performance Magnetic Solutions

At Master Magnetics in Castle Rock, Colorado, we offer high-quality alnico magnets, designed for strength, durability, and performance under extreme conditions. What is alnico? It’s an alloy consisting of aluminum, nickel, cobalt, and other metals, available in two primary types: cast and sintered. Cast alnico magnets are formed through molten metal casting, making them customizable for industrial and automotive uses. Sintered alnico magnets, on the other hand, are made using compressed metal powders, ensuring high precision and reliability in critical applications like ignition systems and sensors.

The alnico vs neodymium debate often comes down to heat resistance and mechanical strength. While neodymium offers stronger magnetism, alnico is far more stable in high-temperature environments and is less prone to corrosion. This makes it ideal for automotive, aerospace, and industrial applications where consistent magnetic performance is critical. Additionally, alnico magnets for pickups are widely used in electric guitars, offering the classic warm tone preferred by musicians.

At Master Magnetics, we provide cast and sintered alnico magnets in various sizes and shapes, meeting strict International Magnetics Association (IMA) standards. Whether you need magnets for motors, security systems, or electronics, we have the right fit for your application. Order your alnico magnets today for unmatched reliability and performance!
