Bonded Neodymium Magnets are a type of rare-earth magnets made of neodymium that are permanently bonded to a variety of materials, such as plastic, stainless steel, and other metals. These magnets are ideal for applications that require a lighter weight, greater strength, and higher temperature resistance than traditional magnets. Bonded Neodymium Magnets come in a variety of shapes and sizes, including disc, block, cylinder, ring, and other custom shapes. They are available with a range of coatings, such as epoxy, nickel, parylene, and other options. Bonded Neodymium Magnets have a maximum operating temperature of 120°C-150°C and can be packaged in carton box, pallet, and other forms. Neodymium-bonded magnets are an ideal choice for applications requiring superior magnetic performance and a lighter weight.
