Alnico Magnets

Alnico magnets are high-performance permanent magnets manufactured from a blend of aluminium, nickel, and cobalt. They are best known for their excellent temperature stability, long service life, and resistance to demagnetisation, making them ideal for industrial and electrical applications.

Unlike neodymium magnets, Alnico magnets retain their magnetic properties at very high temperatures (up to 450°C) and perform reliably in demanding environments where heat resistance is critical.

• Excellent performance at high temperatures
• Stable magnetic properties over time
• Good resistance to corrosion (often no coating required)
• Long service life
• Available in cast or sintered grades

While neodymium magnets offer higher pull force, Alnico magnets excel in high-temperature environments and applications requiring long-term magnetic stability. They are best used in closed magnetic circuits to maintain optimal performance.
