    Grades of Neodymium :
    N35, N38, N42, N38SH…what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the ‘N’), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) – M – H – SH – UH – EH. You find the temperature rating of each grade on our Specifications of Neodymium Magnets Page.

    Platings/Coatings :
    Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. There are a variety of options for coatings, but nickel is the most common and usually preferred. Some other options for coating are zinc, tin, copper, epoxy, silver and gold.

    Machining :
    Neodymium material is brittle and prone to chipping and cracking, so it does not machine well by conventional methods. Machining the magnets will generate heat, which if not carefully controlled, can demagnetize the magnet or even ignite the material which is toxic when burned. It is recommended that magnets not be machined.

    Demagnetization :
    Rare Earth magnets have a high resistance to demagnetization, unlike most other types of magnets. They will not lose their magnetization around other magnets or if dropped. They will however, begin to lose strength if they are heated above their maximum operating temperature, which is 176°F (80°C) for standard N grades. They will completely lose their magnetization if heated above their Curie temperature, which is 590°F (310°C) for standard N grades. Some of our magnets are of high temperature material, which can withstand higher temperatures without losing strength. Neodymium Coreless Gear Motor Magnet

    Packing :
    Our packing is done very professionally in a 8 segment thermocole box,With magnets kept in cartons at each mini segment.This doesn’t cause magnetic forces to interact internally in the packing.Thereby there is no risk of chipping the magnets due to cartons sticking together etc.Moreover the ourer carton is covered by PP sacks to make it weatherproof.
