알니코 자석: 고성능 자석 설명
사람들이 강력한 자석을 생각할 때, 네오디뮴 (희토류) 가장 먼저 떠오르는 경우가 많음. 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...
