Neodymium Ball Magnets 5mm

Name: Neodymium Ball Magnets 5mm
Brand: NingBo BeiLun Meank Magnetics Co.,Ltd.

5mm is a small size for sphere rare earth neodymium magnets, which are sold by all magnet dealers. The common coating for 5mm sphere neodymium magnets includes nickel, chromium, chromium, gold, and silver. Various coloured 5mm neodymium magnetic balls are used for neo cube magnetic puzzle toys. We can deliver 5mm magnetic balls wholesale in the type of 216pcs cube shape. The pulling force range of our neodymium magnet balls 5mm series is 0.8-1.2 lb. It is dangerous for children under 3 years older to play with small neodymium magnetic balls including neodymium magnetic balls 10mm.

N35 5mm Sphere Neodymium Magnet Characteristics

Popular Coating: Nickel, Ag, Au, Cr are available for neodymium sphere magnets bulk.

5mm neodymium ball magnets are a classic small-size specification among rare earth permanent magnets. Due to their compact diameter, strong magnetic performance, and high dimensional consistency, 5mm sphere neodymium magnets are widely used in magnetic toys, educational puzzles, industrial assemblies, precision positioning systems, and DIY magnetic structures.

Compared with traditional ferrite magnets, sintered NdFeB (Neodymium Iron Boron) magnetic balls offer significantly higher magnetic strength while maintaining a minimal volume. The 5mm size strikes an ideal balance between handling convenience, magnetic force, and assembly flexibility, making it one of the most popular sphere magnet sizes on the global market.

Surface Coating Options for 5mm Neodymium Ball Magnets

To enhance corrosion resistance and surface appearance, our 5mm neodymium magnetic balls bulk are available with multiple coating options:

NiCuNi (Nickel) – standard, smooth, and durable

Silver (Ag) – decorative finish

Gold (Au) – premium appearance

Chromium (Cr) – high wear resistance

All coatings are applied with uniform thickness to maintain precise diameter tolerance and magnetic consistency.
