Alnico Magnets: High-Performance Magnet Explained
When people think of powerful magnets, neodymium (rare earth) often comes to mind first. But long before neodymium dominated the market, there was Alnico—a magnet alloy that remains irreplaceable in high-temperature and precision applications. From electric guitar pickups to vintage sensors and aerospace components, Alnico magnets continue to play a vital role in modern engineering. Key Takeaways Alnico (aluminum-nickel-cobalt-iron) was the strongest permanent magnet before rare earths, and remains irreplaceable in high-temperature service — it operates up to 550 degC and keeps...
