Ndfeb Ceramic Magnets

A neodymium magnet also known as ndfeb nib or neo magnet is the most widely used type of rare earth magnet it is a permanent magnet made from an alloy of neodymium iron and boron to form the nd 2 fe 14 b tetragonal crystalline structure.

Ndfeb ceramic magnets. The purpose of this discussion is to compare briefly magnetic and mechanical properties of ceramic and neodymium iron boron neo biasing magnets when used in a drop in circulator operating above gyromagnetic resonance mounted on a 90 c base plate with 40 watts of through power. Lynas holds back rare earths production. Please note that all neodymium rare earth bar magnet are fragile and require extreme caution when handling bar magnets due to their brittle nature and to avoid injury due to pinching. Rare earth prices up.

Grade n45 neodymium bar magnets. More 2013 09 21 rare earth prices up 2013 09 21 lynas holds back rare earths.

If a magnet is heated too far beyond tmax it will eventually become demagnetized at a temperature known as tcurie. And international trade laws require all companies buy licensed neodymium ndfeb magnets. What is a ceramic magnet ceramic magnets also known as ferrite magnets were developed in the 1960 s as a low cost alternative to metallic magnets. While their hard brittle quality and low energy exclude them from some applications ceramic magnets have won wide acceptance due to their corrosion and demagnetization.

Developed independently in 1984 by general motors and sumitomo special metals neodymium magnets are the strongest type of permanent magnet available. For china a revival occurs in rare earth exports. Cms magnetics carries samadrium cobalt bar magnets ceramic bar magnets as well. Ceramic magnets have a tmax of 300 degrees celsius as do smco magnets and ndfeb magnets have a tmax of 150 degrees celsius.
