Sintered neodymium iron boron (NdFeB), also known as "supermagnets", is today the most powerful magnetic material, with magnetic properties that outperform traditional materials. The last few years qualities have developed that can withstand high temperatures. NdFeB magnets oxidise easily, therefore we sell our magnets with a surface treatment. Nickel or Zinc are the most common ones, but other treatments can occur.
Our magnetcalculator is a handy tool to specify the holding force for each permanentmagnet. NOTE: Theoretical values, may vary from real world results.
See our facts page for information about the different magnet materials, with a table of all neodymium grades, max working temperatures and which surface treatment that is best for you application.
