In speakers, the common magnet materials are ferrite magnets, rare earth neodymium magnet, and aluminum nickel cobalt magnets. Today, I will talk about the difference and selection of aluminum nickel cobalt and ferrite magnets in speakers.
Aluminum nickel cobalt magnet (Alnico): Aluminum nickel cobalt magnet is an alloy magnet composed of metals such as aluminum, nickel, cobalt, and iron. It has high Coercivity and high temperature coefficient of Coercivity, and is suitable for use at high temperatures. Aluminum nickel cobalt magnets are typically used in specific audio applications, such as tweeters and some professional audio equipment, which require high magnetic field strength and magnet stability.
Ferrite magnets: Ferrite magnet is the most common speaker magnet material. It is a ceramic material composed of iron oxides and some other metal oxides. Ferrite magnets have high Coercivity and permeability, relatively low price, and relatively simple manufacturing process. It is widely used in mid bass speakers and speaker systems, providing stable magnetic fields and possessing good magnetization and demagnetization characteristics.
Ring ferrite magnets for speakers & horns;
Although Alnico magnets have high Coercivity and Coercivity temperature coefficient, their prices are relatively high and their manufacturing processes are complex, so they are seldom used in loudspeaker applications.
In contrast, ferrite magnets are the most common magnet material in loudspeakers.
Our ring horn magnets have a full range of specifications, good sound quality, durability, and long lifespan. They are made of high-quality materials to ensure long-term stability. We welcome inquiries regarding the required specifications.
