Neodymium Magnets & Custom Permanent Magnet Materials
-Product Highlights
MagnetGlobal’s Neodymium Disc Magnets are solid, flat-faced NdFeB magnets without a center hole, supplied across a wide range of diameters and thicknesses. Disc magnets are the most widely used general-purpose magnet shape, suited to everything from small electronics assemblies to large holding and lifting applications.
-Product Highlights
MagnetGlobal’s Neodymium Cylinder and Rod Magnets are precision-ground solid NdFeB cylinders, supplied as raw stock for further machining or as finished components ready for direct installation. These form the same magnetic core material used across our own magnetic rod, grid, and separator product lines — available here as standalone raw material for OEM manufacturers building their own assemblies.
-Product Highlights
MagnetGlobal’s Neodymium Ring Magnets are precision-machined annular NdFeB magnets, produced across a wide range of outer diameter, inner diameter, and thickness combinations. Ring magnets are widely used in motor and sensor assemblies, magnetic couplings, and any application requiring a through-bore for a shaft, fastener, or wiring.
-Product Highlights
MagnetGlobal’s Countersunk Block and Disc Magnets — also known as counterbore magnets or screw-mount magnets — are precision-machined NdFeB permanent magnets with a pre-drilled, countersunk mounting hole for flush screw installation. Available in both rectangular block and round disc profiles, these are widely used by equipment builders, fixture designers, and industrial OEMs who need a reliable, removable magnetic mounting point rather than an adhesive-backed magnet.
Industrial Magnet Materials & Custom Magnetic Components
Permanent Magnets and Materials for Industrial Projects
Permanent magnets can be supplied as individual components for use in equipment assemblies, fixtures, motors, sensors, and magnetic separation systems. Choosing the right magnet involves more than selecting a shape or a surface Gauss reading. Material grade, dimensions, magnetization direction, working temperature, coating, and the surrounding assembly all influence how a magnet performs in its intended application.
The products currently listed in this category focus on neodymium iron boron (NdFeB) magnets in several commonly requested forms. MagnetGlobal can also review inquiries for other specifications and magnetic materials where a standard listed product does not fit the project.
Explore the Magnet Shapes Currently Available
Neodymium disc magnets have flat circular faces and are available in different diameter and thickness combinations. They can be considered for compact assemblies, fixtures, and general magnetic holding applications.
Neodymium cylinder and rod magnets have a solid cylindrical form. Their diameter, length, and magnetization direction should be specified according to how they will be installed and used.
Neodymium ring magnets have a central opening that can accommodate a shaft, fastener, or other assembly feature. When specifying a ring magnet, provide its outer diameter, inner diameter, thickness, and required magnetization direction.
Countersunk block and disc magnets include a mounting hole designed for screw installation. They are useful where the magnet needs a defined mechanical mounting point. Confirm the hole dimensions, screw arrangement, and installation forces before selecting a design. These four product forms correspond to the items currently shown on the page.
Need a Different Magnetic Material or Specification?
NdFeB is often selected when a compact assembly requires strong magnetic performance. For projects involving higher operating temperatures, corrosion exposure, or different cost and performance requirements, other materials such as samarium cobalt (SmCo) or ferrite may be considered. Their suitability and availability should be confirmed against the specific grade, dimensions, working conditions, and order requirements.
Custom inquiries may cover nonstandard dimensions, block or ring profiles, mounting features, protective coatings, and specified magnetization directions. Where possible, provide a technical drawing so the design, manufacturability, tolerance, and inspection requirements can be reviewed together. A required temperature limit should be stated for the complete application, rather than assumed from the name of the magnet material alone.
What Information Helps Us Quote a Custom Magnet?
For an accurate technical review, include the following information with your inquiry:
- Magnet material or intended application
- Shape and dimensions, preferably with a drawing
- Required magnetic grade or performance target, if known
- Magnetization direction
- Coating or surface treatment requirements
- Working temperature and operating environment
- Dimensional tolerances, inspection needs, and estimated order quantity
If the magnetic grade or magnetization direction has not yet been determined, describe how the magnet will be mounted and what it needs to attract, hold, or actuate. This gives the supplier a clearer basis for proposing an appropriate specification.
Frequently Asked Question
Can I request a magnet size or shape that is not listed on this page?
Yes. Send the dimensions or drawing, application details, and estimated quantity for review. The achievable material grade, manufacturing method, tolerance, coating, and delivery terms should be confirmed for the proposed design before an order is placed.
