Magnet shapes & materials

Classify neodymium magnets by shape, grade and condition

Record blocks, rings, discs, segments, assemblies and broken magnets separately, stating their origin, weight and condition.

Magnet shapes & production scrap

Offer neodymium magnets for sale by form and origin

Ring, block, disc, cylinder, segment, HDD assembly or broken magnet: geometry helps with sorting, but is not evidence of the material.

Six categories

Choose the relevant magnet form

Block and rectangular magnets shown for illustration

Block and rectangular magnets

When offering loose block and rectangular magnets or cleanly separated lots for sale, state the dimensions, number of items, total weight, coating and origin.

Open the assessment checklist →
Ring magnets shown as shape examples

Ring magnets

Ring magnets and magnets with a bore are assessed by their outer and inner diameters, height, coating and documented material family.

Open the assessment checklist →
Disc and cylinder magnets shown as shape examples

Disc and cylinder magnets

Disc and cylindrical shapes cannot be identified as NdFeB by appearance alone. Documentation, dimensions, how consistently the lot is sorted and origin are relevant to the initial assessment.

Open the assessment checklist →
Segment and arc magnets shown as shape examples

Segment and arc magnets

Rotor segments and arc magnets are used in motors and generators. Loose segments and complete rotors require different system boundaries.

Open the assessment checklist →
HDD and actuator magnets shown as shape examples

HDD / actuator magnet assemblies

Describe dismantled hard-drive magnets, actuator assemblies and sorted IT returns separately, distinguishing the magnet, steel back iron and the status of any data-bearing media.

Open the assessment checklist →
Broken magnets and production scrap shown as form examples

Broken magnets & production scrap

Broken magnets, rejects, and sawing or grinding residues may be concentrated material streams. The process stage, medium, moisture and foreign materials determine whether they can be assessed.

Distinction

Shape does not determine the material

NdFeB

Often silver-coloured because of their coating, but they cannot be reliably identified by appearance.

SmCo

A separate rare-earth magnet family; record it separately and do not mix it with NdFeB.

Ferrite

Ceramic permanent-magnet material without rare-earth elements; generally requires a different recovery route.

AlNiCo

Aluminium-nickel-cobalt permanent-magnet material; not NdFeB.
