A magnet shaped in the form of a circular disk, with a thickness less than its diameter; that attracts iron & produces a magnetic field. These magnets usually are magnetized through the length/thickness (axially) , but may also be magnetized diametrically (around the rim). The magnetic poles & strengths vary specifically to each individual magnet produced. Neodymium disc magnets are the strongest permanent disc magnets produced, used widely for holding purposes; like jewelry cases, high-end packaging, magnetic therapy, & crafting
Over 130 rare earth magnets are available with the diameters from ¼” to ½” . Special sizes can be ordered as Custom Made Magnets.
These powerful magnets come in grades that include N35, N42, N45, N50, and N52. The Residual Magnetic Flux Density is from 13,500 up to 14,400 Hauss or 1.35 to 1.44 Tesla. Our ½” diameter rare earth magnets have a pulling force ranging from 1.3 lbs to 45 lbs.
All manufacturing tolerances are +/- .002” on all dimensions. Maximum Operating Temperatures vary by Grade (see individual magnet products below)

About Neodymium in General
Q. What are the strongest magnets? A. The strongest permanent magnets are rare earth magnets. The rare earth magnet's family consists of samarium cobalt magnets & Neodymium magnets. The neodymium magnets at grade n52 are currently the strongest magnets worldwide & truly are "industrial strength".rare earth magnets. Q. What is a permanent magnet? A. A permanent magnet is a magnet that cannot be turned off as in an electro-magnet. All neodymium magnets are permanent (always attracting) Q. What is rare earth and where does it come from? A. Rare earth is an ore dug from the earth, primarily in China that 15 metal chemical elements having atomic numbers 57-71. You can find these elements near the bottom of the Periodic Table of the Elements in the lanthanides family. Q. Where is neodymium found? A. Neodymium is mined as an ore primarily in China. China is also where almost all of the processing into the neodymium alloy (that we know as neodymium) is done. Neodymium alloy consists of Neodymium, Iron & Boron. Still in China, alloy it is shaped into the discs, cylinders, rectangles, spheres & more that we know as finished magnets.
Neodymium magnets overall, are the world's strongest permanent magnets. Although, not all neodymium Disc magnets share the same characteristics. The Grade of a Neodymium Magnet will provide an idea of the strength of a neodymium magnet. The most common commercially available grades generally run N35- N52. N35 is the weakest (but by no means weak) and N52 is currently the strongest. There are some special use grades as well. A larger piece of neodymium of a weaker grade may be ultimately stronger than a smaller but higher grade piece. Our strong disc magnets are designed & manufactured to meet stringent quality standards of both external and our own standards.
