Some specialized neos work at higher temperatures, but generally above that level they fail to properly function.
Neo magnets crack#
Neos are also susceptible to temperature differences and can crack or lose their magnetism in higher temperatures, usually above 176 degrees Fahrenheit. This can sometimes pose problems because the magnetic power is so great that if the neo connects too rapidly with a lot of momentum, it can chip or crack itself. Due to the iron in a neo, it has properties similar to other ferromagnetic materials, including mechanical fragility. The official chemical designation of a neo is Nd 2Fe 14B. This neodymium is ground up into a fine powder, which can then be resealed into a desired shape once combined with iron and boron.
In order to construct a neo, as they are sometimes also called, manufacturers collect rare earth metals and sift them to find usable neodymium, which they must separate from other minerals. Depending on the shape, the composition, and the production method, NIB magnets can fall anywhere in this range and provide serious lifting strength. Neodymium magnets, also known as NIB magnets, are measured from N24 to N55 on the magnetism scale that goes up to N64, which is a theoretical magnetism measurement. Because of their strength, neodymium magnets are used in a broad range of applications, including jewelry, toys and computer equipment. Although a “rare” earth metal, neodymium is widely available, leading to easily obtainable raw materials to manufacture neodymium magnets. Neodymium magnets are the strongest known relative to their mass, with even small magnets able to support thousands of times their own weight. Neodymium is a rare earth metal component mischmetal (mixed metal) which can be used to create powerful magnets.
