Permanent magnet ferrite manufacturers in China For Motorcycle Motor W2021J
Motorcycles bring convenience to life:
Fast movement: Motorcycles are small and flexible, and can navigate dense urban traffic easily, reducing travel time, especially during peak periods.
Economical: Compared with cars, motorcycles have lower purchase costs and daily maintenance costs, especially in the fuel economy performance, suitable for many people to choose.
Convenient parking: The parking space occupied by motorcycles in the city is smaller, and parking is more convenient, which solves the problem of urban parking.
Adaptable to a variety of road conditions: Motorcycles can adapt to a variety of complex road conditions, including narrow laneways and unpaved roads, suitable for diverse use needs.
Reduce congestion: Motorcycles can effectively reduce urban traffic congestion, improve the overall traffic mobility, and provide convenience for urban traffic management.
What's the key advantages of ceramic strontium ferrite magnets made by wet compression molding?
Low cost - Strontium ferrite is inexpensive and the wet molding process is relatively simple. This makes them cheaper than rare-earth magnets.
High magnetic property-Even without heavy rare earth element additions, strontium ferrite magnets can achieve coercivities of 700-1000 kA/m, making them suitable for many applications.
Dimensional consistency - The compression molding process allows for close dimensional tolerances and uniform magnet shapes to be produced consistently.
Temperature stability - Strontium ferrite magnets have high Curie temperatures, typically around 450-470°C. They maintain good magnetic properties over a wide operating temperature range.
Resistance to corrosion - Being fully dense ceramic materials, they are not prone to corrosion like bonded magnets containing additives.
Mass production capability - The molding process is amenable to automated high-volume manufacturing of complex magnet geometries.
