Audited Supplier N52 Black epoxy Neodymium Magnet disc NdFeB Magnet
Products description
NdFeB magnet, the third generation of rare-earth permanent magnets, is the most powerful and advanced permanent magnets today.
NdFeB is named as"Magnet King" for its high remanence, high energy. Moreover, it has high performance and high-cost ration,
because of the rich rare earth resources in China and the ever-changing production process and technological progress. It can be
easily formed into various sizes and different shapes, such as segment, ring, block, etc. Neodymium magnets Supplier
Epoxy coating neodymium disc magnets Neodymium disc magnets with Epoxy coating overcome the corrosion problems associated with traditional Nickel-based coatings. This makes them ideal for outdoor use and locations where exposure to corrosive elements occurs, including Marine, Industrial and Agricultural environments. Epoxy also increases mechanical strength to the normally brittle Neodymium material and makes the magnet more durable. However, the added cost and the air gap created by the coating make Epoxy coated magnets slightly less powerful and more expensive. Higher magnetic grades like this N50 item are used to help overcome this reduction in power. For specialized, long term use in exposed environments, Epoxy coated Neodymium magnets can provide long-lasting performance and increased durability in situations where uncoated magnets would degrade and eventually fail.
How to safely separate the disc neodymium magnets?
Application: sensors, motors, rotors, wind turbines, wind generators, loudspeakers, magnetic hooks, magnetic holder, filters automobiles and so on.
