Custom Magnets, Made to Your Drawing

Acorn Magnet makes custom sintered neodymium magnets for OEM and engineering teams. We do not sell catalogue parts. Every project starts from your drawing, your sample, or your application requirement.

Our focus is precision and preparation. We agree the specification with you before production starts. That way the first batch and the tenth batch match.

  • Custom shapes and sizes, machined from your CAD file or sample
  • Grades from N30 to N38AH, with high-temperature series available
  • Coatings chosen for your working environment
  • Magnetization direction matched to your magnetic circuit
  • Both sides data confirmation before shipment

Not sure where your part fits? Tell us what your device has to do and we will point you to the right material and shape.
