Neodymium magnets have excellent magnetic properties and are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace and other fields. The most common are permanent magnet motors, speakers, magnetic separators, computer drives, magnetic resonance imaging equipment and instruments, etc.
What should be considered when processing neodymium magnets?
What is the production process of neodymium magnets?
How are neodymium magnets sorted?
Neodymium magnets have a very strong attractive force. However, they are very brittle, which means they crumble easily. For this reason, neodymium magnets should not be machined. This is because machining can cause the magnets to chip and break.
Also, machining magnets often generates a lot of heat. As mentioned earlier, too much heat can lead to demagnetisation.
The process flow of neodymium magnets: Batching → Melting and ingots / spinning → Pulverising → Pressing → Sintering and tempering → Magnet testing → Grinding → Pin cutting → Electroplating → Finished product. Among them, ingredients are the basis, and sintering and annealing is the key.
NdFeB magnetic blank production tools and performance testing tools: melting furnace, belt furnace, jaw crusher, jet mill, press moulding machine, vacuum packing machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic performance tester, Gauss meter.
NdFeB magnet processing tools: centreless grinding, spheronising machine, double end grinding, surface grinding, slicer, double sided grinding, wire cutting, bench drill, special shape grinding, etc.
Neodymium magnets come in different grades, and as a magnet novice, it is important to understand these grades. This is because a proper understanding of neodymium magnet grades will help you make better decisions when choosing a magnet fishing magnet.
When you search for a neodymium magnet grade, you will find the letter "N" followed by some numbers. The "N" stands for neodymium and the following numbers indicate the maximum energy produced by the magnet.
For example, you will see neodymium magnet types such as N30, N35, N42, N50, etc. Without getting too technical, you should know that the larger the number, the stronger the magnet. This means that N52 magnets pull more weight than N35 magnets.
So the higher the demand for magnets, the higher the magnet power should be. But in general, when it comes to using strong magnets, we would recommend choosing a magnet that is no higher than N42. As the power of N42 belongs to the middle class, the magnetic properties are very strong. In general, magnet qualities below N42 can meet the requirements of most applications. If you have strict magnetic attraction requirements, you can choose magnets with a performance above N42 or N52.
