Neodymium Ring Magnets

Strong Rare-Earth Ring Magnets

Neodymium ring magnets are strong Rare-Earth magnets, circular in shape with a hollow center. Neodymium (also known as “Neo”, “NdFeb” or “NIB”) ring magnets are the most powerful magnets commercially available today with magnetic properties that far exceed those of other permanent magnet materials. Due to their high magnetic strength, neodymium ring magnets have replaced other magnetic materials in order to make a design smaller while achieving the same result.

Neodymium Ring Magnets in Assorted Sizes and Shapes

We stock licensed neodymium ring magnets in different lengths, OD/ ID diameters, finishes and premium grades. Finishing options for NdFeB ring magnets are uncoated, with a triple- coating (Ni-Cu-Ni) nickel finish for optimal corrosion resistance. Not all of our magnets are shown on this website so please contact us today if you don’t see what you are looking for.

Neodymium Ring Magnets in Premium Grades & Sizes

We offer a large inventory of licensed neodymium magnets from micro-sized disc magnets measuring 0.1” in diameter to large cylinder magnets that hold up to 68 lbs. Premium grades range from N30 to N52 which is the highest grade available in today’s market.

We carry a large inventory of neodymium Ring magnets, not all of which are shown on this website. Contact us today or send us a special request and let us know what you are looking for.

Manufacturing Methods for Neodymium Magnets

Our neodymium Ring are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings.  

Standard Measurement Tolerances for NdFeB Magnets

Standard tolerances are +/- 0.05mm on both diameter and thickness dimensions. 

Neodymium Ring Magnet Applications

Neodymium ring magnets have remarkable holding power for their size, so they are ideal for all types of applications. From craft & model making projects to high-performance motors, medical devices, audio components, science and research projects, trade shows, POP displays and much more. 

Custom Orders for Neodymium Disc Magnets

We can also custom manufacture neodymium ring magnets to your exact specifications, just send us a special request and we’ll work with you to determine the best solution for your specialty project.
