Why are N45 and n52 magnets more expensive than N35
First of all, from the material price. The material prices of N45 and n52 are much higher than those of N35, tens of yuan per kilogram higher.
Secondly, in terms of performance, the magnetic force of N35 is far less than that of N45 and n52. They are mainly different in remanence, coercivity and maximum energy product. The magnetic force of N35 is smaller than that of NdFeB. The larger the number is, the stronger the magnetic force is, and the price difference is relatively large.
In terms of magnetic force, for example, a D10 * 10 cylindrical magnet of N35 can absorb about 1kg of things, and N45 of the same size can absorb about 1.5kg of things. Therefore, N45 is more expensive than N35, N38 and N40.
