Ferrite magnets, also known as ceramic magnets, remain a widely used and cost-effective solution in permanent magnet technology. Made primarily from iron oxide and barium or strontium carbonate, they offer good magnetic performance for their price and excel in chemically aggressive or moist environments.
While their energy density is lower than that of rare-earth magnets, ferrite magnets provide high stability across a wide temperature range and are inherently corrosion-resistant. They require no additional coating and are ideal for outdoor, automotive, and consumer electronics applications.
