Neodymium magnets – also called NdFeB, strong magnets – are the strongest permanent magnets in the commercial magnetic materials market. It has a maximum energy product of 26 MGOe to 52 MGOe. A neodymium magnet is a permanent magnet made from an alloy of neodymium, iron, and boron, which form a Nd2Fe14B tetragonal crystal structure. […]

Neodymium magnets have the strongest magnetism, but we have to use them properly to keep them magnetic. Otherwise, they can lose their magnetism under high-temperature conditions. This is not a quality issue of the neodymium magnets, but the nature of this type of material. Osenc is a custom neodymium magnet supplier, and we will tell
Neodymium magnets are very strong and can be dangerous if you use them improperly. They can cause injuries to you such as cuts, bruises, and broken bones if they slam together. Meanwhile, neodymium magnets have disadvantages of their own. They can be brittle and may break, shatter or corrode under certain conditions, so it is

Generally speaking, neodymium magnets have 2 types of popular production techniques – sintered neodymium magnets and bonded neodymium magnets. The difference between them is mainly in the forming processes. Bonded neodymium magnets are made by adding neodymium powder to the binder. The bonding process is essentially the same as injection molding. Meanwhile, sintering is vacuuming

Step 1: Mining (Ore) This is the beginning of the entire neodymium magnet supply chain. It is the mining of large quantities of ore containing a mixture of rare earth minerals. Rare earth elements (REEs) exist in large mixed deposits, such as cerium fluorocarbon, monazite, and yttrium phosphate ores. These deposits contain large amounts of

What is neodymium magnet rust? Neodymium magnet rust is a big problem during the production process. People have to add a magnet coating to the magnet to protect it Neodymium magnets are the 3rd generation of rare earth permanent magnets. They have excellent magnetic performance, mechanical processing characteristics, and high cost-effectiveness. For these reasons, they

What is salt spray testing? Salt spray testing is a laboratory simulation of a corrosive saline environment, also known as salt fog testing. It is used as an accelerated means of testing the ability of surface coatings to withstand atmospheric corrosion. Some applications, e.g. in sea transport or generally in contact with sea water, require

Magnet Tolerance is one of the important factors in neodymium magnet purchasing. It includes dimensional tolerance and form tolerance. Neodymium magnets are important units for manufacturing many application. They are critical components for high-tech products like motors, horns, testing instruments, etc. That is why buyers have certain requirements for the dimensional tolerance and form tolerance of
Neodymium magnets are comparatively smaller than many consumer products. Especially custom neodymium magnets and micro neodymium magnets, some are as small as the sales packages of smartphones. Shipping strong neodymium magnets by air is a very good choice. Generally, this shipping method can fulfill delivery to most destinations around the world in a week. However,
