Have you ever picked up a magnet and wondered which one is the strongest? N52 is the strongest magnet grade among the three. When I look at the N42 vs the N52 magnet, I see that the N52 pulls much harder than the N42 or the N45. I always check n42 vs n52 magnet before I buy […]

In factories, a magnetic drum is a machine used to separate magnetic metals like iron from other materials. As the drum spins, it pulls out metal pieces using a strong magnet. This helps protect other machines and makes the final product cleaner and safer. Magnetic drums are commonly used in recycling, mining, food processing, and

Many people ask me, what is a disc magnet? A disc magnet is a round, flat magnet with strong magnetic fields focused on its flat surfaces. These magnets look simple, but their shape makes them stand out. Understanding magnetic field basics helps you see why disc magnets work so well in daily life. I see disc magnets

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
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
