Ferrochrome-cobalt magnetic rings are ring-shaped magnets made from permanent magnet materials primarily composed of iron (Fe), chromium (Cr), and cobalt (Co). They exhibit excellent high-temperature resistance and stable magnetic properties. Their magnetic properties fall between those of AlNiCo and ferrite magnets, maintaining high remanence while offering outstanding resistance to demagnetization. They sustain a stable magnetic field even in high-temperature environments ranging from 200°C to 400°C.
