WHAT SHOULD BE NOTED WHEN BUYING big NEODYMIUM MAGNETS
1. Make sure you really need a big magnet
We have met many customers who offered to buy magnets. But just a few of them really needed it. In many cases, their needs can be met with magnetic assembly, likes Halbach.
2. Make sure you are a professional or have received
professional training and know-how to handle magnets.
“Maybe all of us know neodymium magnets. They are some type of permanent magnets made of rare earth elements. As the kind of magnetic objects that can be bought, neodymium magnets generate extremely strong magnetic fields. Because of this unique and remarkable characteristic, neodymium magnets are not only widely used in the manufacture of robots, but also in the fields of technology and science.
Neodymium magnets are very powerful. The bigger they are, the more you need to be careful to avoid being hit or squeezed by their attraction.
Another physical feature that makes big neodymium magnets difficult to handle mechanically is that these magnets are very brittle and will become many small pieces if impacted. Therefore, in order to prevent this from happening, the manufacturers of these magnets coat them with a layer of higher physical strength.
Neodymium magnets cannot be made very big. And their pull is very strong. It is almost impossible to connect a big magnet to any other magnet or any metal object. If two magnets are attracted together, it is very difficult to separate the two big magnets.
3. lead time and shipping time is long
This includes production time as well as transportation time. Because the big magnets are all customized, the factory generally does not have raw materials. Therefore, the production time will be longer than the small size. Normally, when producing a big magnet, the factory will definitely prepare a spare part. just in case. Sometimes it may be the first time that it fails to meet the standard and needs to be re-produced. This leads to a production time of as long as 40-80 days. In most cases, that is 40days.
We recommend that all big size magnets be shipped by sea. Because this is the most cost-effective. If it is shipped by air, the cost is very high. And we only ship orders with an even number of products by air.”
