Neodymium Ring Magnet are great for loudspeaker, home theater, multimedia, headset, water meter, vibration motor, etc.
Sintered NdFeB Magnet Ring are supplied in different grades and sizes, maximum diameter 220mm, minimum thickness 1.0mm. Ring magnet, which are magnetized through thickness (axially), north pole and south pole are located on the top and bottom. Axially magnetized is common magnetism for ring magnets. Diameterically magnetized also can be made as per customer’s different requirement.
Neodymium magnets are sensitive to temperature change and even lose magnet properties at high temperature
Neodymium magnets lose -0.09 ~ -0.13% of Br/oC and can work stably under 80oC for low Hci Neodymium magnets and 150oC for high Hci Neodymium magnets.
Neodymium magnets are corrupted in humid environment
Surface protection is strongly recommended, such as plating, varnishing and encapsulating.
Neodymium magnets are hard and brittle
Neodymium magnets can be abrasively machined with coolant served to absorb heating and dust. Without coolant, rare earth magnets could crack and chip by the heat produced during high speed cutting or grinding, and the sparks contain the easily oxidized grinding dust that could cause fire!
Tolerance of Neodymium magnets
Unless otherwise specified, tolerance on dimension of magnetization is +0.005″. Other dimensions are +1.5% or +.010″, whichever is greater. Neodymium Iron Boron Large Countersunk Ring Magnet N42H OD120mm
Sintered NdFeB magnets are produced by sintering from the mixture of rare earth materials neodymium-iron-boron. They have the highest energy among current permanent magnets and can be supplied in many shapes and sizes.
APPLICATION: Automotive industry: for starters, distributors, ignition, etc. Consumer electronics: loudspeaker parts, linear motors, etc.
