Neodymium Ring Magnets

Name: Neodymium Ring Magnets
Brand: Ningbo Beilun Meank Magnetics Co.,Ltd.

Circular neodymium magnets, featuring a flat and round shape with a central hole, are referred to as strong neodymium (NdFeB) ring magnets. Their diameter exceeds their thickness.

Neodymium ring magnets boast stable magnetic performance, strong magnetic force, and a long lifespan, making them widely used in manufacturing motors, generators, sensors, and other devices.

Surface Treatment is Needed for Rare Earth Ndfeb Strong Magnet Rings

Strong neodymium(NdFeB) ring magnets are not rust-resistant and easy to corrode, and their surface needs to be coated, generally including zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel copper-nickel, environmental protection nickel copper-nickel, epoxy coating, etc.
