Neodymium Magnetic Balls

Name: Neodymium Magnetic Balls
Brand: Ningbo Beilun Meank Magnetics Co.,Ltd.

Sintered NdFeB magnets can be customized into various shapes,the round and sphere shaped neodymium(NdFeB) magnets are known as neodymium magnetic balls. we just use the diameter size to express a ball shape magnets.Colorful rare earth neodymium magnetic balls are widely use for magnetic toys.

Neodymium magnetic balls: Custom, versatile, and machinable. Crafted from premium NdFeB material, available in various sizes. No molds required; tailored to meet unique specifications for endless applications.

Surface Treatment of Strong Rare Earth Ndfeb Magnetic Balls

Strong neodymium(NdFeB) magnetic balls are not waterproof and easy to corrode, so rustproof surface treatment needed, generally including zinc plating, nickel, environmental protection zinc, environmental protection nickel, nickel copper nickel, environmental protection nickel copper nickel,epoxy coating etc.
