Neodymium is a metal which is ferromagnetic (more specifically it shows antiferromagnetic properties), meaning that like iron it can be magnetized to become a magnet, but its Curie temperature (the temperature above which its ferromagnetism disappears) is 19 K (−254.2 °C; −425.5 °F), so in pure form its magnetism only appears at extremely low temperatures. Below is an overview of these properties:-. The Neo magnets are less brittle than SmCo. Mounting Magnets Gold and Silver plating is actually a Gold or Silver layer on top of standard NiCuNi. 900KA/m iHc at 150°C, min. NdFeB Magnete Neodym-Eisen-Bor (NdFeB), auch als Seltene-Erden-Eisenmagnete bezeichnet, bestehen hauptsächlich aus Eisen, Neodym, Bor und anderen Spurenelementen. Bonded var dimensions='Dimensions'; Rubber Coated Magnets Some NdFeB grade are demagnetised to half their maximum performance with a proton beam radiation of 4 x 106 rads and are completely demagnetised with a proton beam radiation of 7 x 107 rads. This property is higher in NdFeB alloys than in samarium cobalt (SmCo) magnets, which were the first type of rare-earth magnet to be commercialized. NdFeB magnets are sintered anisotropic materials - they have a preferred direction of magnetisation locked into their structure. Sortierung: 1 von 5. How to test real silver using neodymium magnets: document.ready=function(){ Please note that any claims that a NdFeB magnet will not corrode is misleading. NdFeB permanent magnets are … They contain three basic elements neodymium, iron and boron. var grade='Grade'; Recycling of critical metals from sintered NdFeB permanent magnets has attracted a lot of attention over the last decade, whereas the recycling of (polymer or resin) bonded NdFeB magnets has been largely neglected.
