AlNiCo magnets, introduced in the 1930s, are renowned for their stable magnetic properties and high temperature resistance. They are produced in both cast and sintered forms, with energy products ranging from 1.3 to 10.1 MGOe. Their versatility and reliability make them ideal for demanding applications.

Key Features:

• High Remanence: Cast Alnico magnets achieve a remanence of up to 1.35 T.
• Temperature Tolerance: Suitable for high-temperature applications with a maximum operating temperature of up to 538 °C.
• Corrosion Resistance: Offers excellent resistance to corrosion, enhancing longevity in various environments.
• Magnetization: Easy to magnetize, providing stable and reliable magnetic performance.

Cast Alnico Magnets:

• Composition: Typically consists of 8-12% aluminum (Al), 15-26% nickel (Ni), 5-24% cobalt (Co), up to 6% copper (Cu), up to 1% titanium (Ti), with the remainder being iron (Fe).
• Applications: Commonly used in sensors, speakers, meters, and various electronic devices due to their high remanence and good temperature coefficient.

Sintered Alnico Magnets:

• Advantages: Offers better machinability and is suitable for smaller and more complex geometries.
• Applications: Ideal for micro-motors, instrumentation, communication devices, magneto-electricity switches, and specialized sensors.

AlNiCo magnets are designed to perform reliably under high temperatures and harsh conditions, making them a valuable choice for critical applications requiring stable magnetic properties.
