Product advantages

Strong magnetic power:

Neodymium spherical magnets are considered to be the strongest magnets among permanent magnets. These magnets have a powerful magnetic field of about 1.4 Tesla, while the ferrite magnets’ magnetic field is 0.5-1 Tesla.

Low density:

Thanks to their low density, Nd-Fe-B ball magnets are applied to modern industries to make lightweight instruments.

High coercivity:

The coercivity of neodymium ball magnets is quite high, offering these magnets huge strength in tough environments.

Magnet Type

Neodymium Magnet Balls

These magnet balls provide the strongest magnetic force given the superior qualities of neodymium magnets. In making neodymium magnets, iron and boron are combined to this rare earth metal.

Samarium Cobalt Magnet Balls

While displaying lower magnetic capability than NIB magnetic balls, SmCo magnet balls have superior resistance to oxidization. This means you can use this magnetic balls in humid environments or where there is a lot of moisture presence.

Ferrite Magnet Balls

Ferrite/ceramic magnets combine iron oxide and either oxides of strontium or barium in their alloying material. Magnetic balls made from ferrite magnets are more affordable given their lower cost compared to neo and SmCo magnets.

Application

Education & Science
Widely used in STEM education, these balls help demonstrate magnetic fields, polarity, and geometric structures. Students can build 3D molecular models, explore magnetic attraction and repulsion, and visualize complex spatial arrangements, enhancing conceptual understanding through hands-on learning.

Art & Design
Artists and designers use magnetic balls to create dynamic, reconfigurable sculptures and jewelry. Their ability to form stable, symmetrical shapes—such as geodesic domes, fractals, or abstract forms—enables endless creative expression.

Therapy & Stress Relief
In occupational and mindfulness therapy, magnetic balls are used as fidget tools to improve focus, reduce anxiety, and enhance fine motor skills. The repetitive motion of connecting and rearranging the spheres provides a calming sensory experience, beneficial for individuals with ADHD, autism, or stress-related conditions.

Engineering & Prototyping
Engineers and hobbyists utilize magnetic balls for rapid prototyping of magnetic circuits, mechanical joints, and kinematic models. Their uniform shape and predictable magnetic behavior allow for quick assembly and testing of concepts without the need for adhesives or fasteners.

Process

Powder Production: Depending on the magnet type, neodymium or SmCo or ferrite, the raw materials are prepared by mixing in the desired ratios. The raw materials are thereafter mixed and processed to form a fine powder.

Pressing and Sintering: The magnetic powder is then pressed into balls using a die system or mold. The pressed balls are then subjected to a high-temperature sintering process to fuse the powder particles together.

Machining: Machining helps achieve precise dimensions and shapes for your magnets, for sensitive applications. It smoothens out the surface while also preparing it for surface treatment and coating.

Coating and Surface Treatment: Coating magnetic balls, especially when using neodymium magnets, is essential for corrosion protection. Use of surface treatments rids the surface of magnetic balls from scratches and markings.

Magnetization: This is typically done simultaneously on multiple balls to align their magnetic domains. Aligning these domains results in the development of a magnetic field and hence acquisition of magnetic properties.

Custom

Sizes & Shapes

We offer neodymium magnets in sizes from 0.010" to large assemblies, with standard shapes like discs, blocks, rings, and arc segments. Custom shapes can be made to your specs.

Grades & Coatings

Available in grades N35 to N52. To prevent corrosion, magnets are coated with options like Nickel (Ni-Cu-Ni), Gold, Chrome, Copper, Epoxy, Teflon, and Rubber/Plastic.
