Comparison of Ferrite and Neodymium Magnet: Which Is Better For Your Needs?
Magnetic materials are an inseparable part of modern industry, technology and recycling. The most widely used magnet types include ferrite magnets and neodymium magnets.
Both feature unique characteristics and are suitable for specific applications. This article will help you understand the differences, advantages, and disadvantages of these two magnet types.
What are ferrite and neodymium magnets?
Ferrite magnets
They are made of ceramic materials containing iron oxide and other metal oxides. They are known for their affordability and resistance to high temperatures.
- Features of ferrite magnets: Good corrosion resistance and lower magnetic force.
- Advantages of ferrite magnets: Low price, thermal stability, suitability for outdoor use.
