Sintered NdFeB magnets are the strongest magnets available in the world. A very small piece of magnet can hold objects several times than its own weight. The raw material neodymium is the key factor for neodymium magnets in terms of costs. The sharp price increase for neodymium and other rare earth metals needed for the manufacture of neodymium magnets therefore changes the prices of your magnetic product a lot suddenly.
When designing products, keep magnet simple and small.
NdFeB magnets are brittle and difficult to machine. The simpler the shape, the easier the magnet is to process, the lower the scrap rate, and the cheaper the processing cost. If you are new to magnet, you may need to seek the advice of a magnet expert.
China Magnets Source is happy to help you with any question of your magnet design, from magnet material selection, magnetic circuit design, simulation calculations to prototype production.
Try more samples.
There are many grades of NdFeB magnets according to different magnetic properties and working temperature. Choosing a magnet is not simply a matter of choosing a high grade with a high magnetic force. Excess magnetism can lead to waste of rare earths and increased costs.
You need to work through a variety of neodymium magnets to find a balance between size and pull strength. N42 grade offers a high performance at an economical price. It is the most commonly used neodymium magnets among N rating. For even higher temperatures, N50M, N48H and N42SH are popular for industrial application.
Choose other cheap magnet materials.
If you need magnet for a low value product, there is no restriction on the size of the product, and the magnetic force of the magnet is not high, you can consider using cheaper material to replace NdFeB, such as ferrite magnet. China Magnets Source not only provides NdFeB, but we also provide high temperature samarium cobalt and alnico, as well as ferrite magnets.
Find the right magnet supplier.
An experienced magnet supplier should not only provide support in magnet price, but also provide a full set of support in all aspects such as magnet selection, sample, transportation and after-sales service, improve communication efficiency and save customers’ time. As the saying goes, time is money.
