Aimants Alnico: Magnétisme Haute Performance Expliqué
Lorsque les gens pensent à des aimants puissants, néodyme (terre rare) vient souvent à l'esprit en premier. 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...
