China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnets in accordance with whether or not they contain rare earths can be divided into containing rare earth magnets, not containing rare earth magnets, these 2 types are commonly used by customers, containing rare earth magnets in the website to introduce more articles, today mainly to introduce the non-rare earth magnets, including its definition, types, advantages and disadvantages, as well as applications.
Short introduction to non-rare earth magnets;
Non-rare earth magnets are magnets that do not contain rare earth elements (such as lanthanum, cerium, neodymium, praseodymium, etc.), relying on common elements such as iron, cobalt, nickel, aluminum, etc., which have lower magnetic properties than rare earth magnets, but offer cost advantages and specific environmental adaptability.
The main types of non-rare-earth magnets include ferrite magnets, alnico magnets, ferrochrome cobalt magnets, and soft magnetic materials, etc. The following is a description of each type.
Non-rare earth ceramic ferrite blocks magnets
Ferrite Magnets: One of the most common non-rare-earth magnets, usually made from iron oxides (Fe2O3) combined with other metal oxides (e.g., strontium, barium), and can be made into rings, circles, arcs, rectangles, cylinders, and special shapes, Mainly used in audio speakers, power tools, automotive appliances, inductors, sensors, office supplies and so on.
Alnico magnets: Alloy magnets synthesized from aluminum, nickel, cobalt and other metal elements (e.g., copper, iron) are mainly used in motors, sensors, instruments, generators, musical instruments and so on.
FeCrCo Magnets: Comparison of a non-rare earth magnets niche, small practitioners for many years only experienced a few customers to this, the main elements of iron, chromium, cobalt, excellent plasticity, corrosion resistance is very good, mainly used in precision instruments, aerospace instrumentation, medical equipment and so on.
Soft Magnetic Materials: Soft magnetic materials are those whose magnetic properties are easily altered by an external magnetic field, but which can also quickly eliminate the external magnetic field, such as silicon steel, manganese-zinc ferrite, and nickel-zinc ferrite, which are not usually used for persistent magnetic field generation, but are very important in electromagnetic devices.
Advantages and disadvantages of non-rare earth magnets
Advantages are relatively low cost, good stability and adaptability, and environmental friendliness. The disadvantages are that they are not as magnetic and often require a larger volume to produce the same magnetic force.
