ES Metall assesses enquiries from sellers of loose neodymium magnets, magnet scrap, broken magnets, rotors and documented manufacturing scrap. For an initial assessment, we need photographs, weight, origin, condition and any available documents.
Neodymium · praseodymium · dysprosium · terbium
Applications compared
The ranking distinguishes measurements, manufacturer statements, traceable calculations and literature assumptions. This makes clear what is documented and what serves only as a reference.
01B-C · Transparent factor-based calculation
NdFeB per 5- to 15-MW reference turbine
These are calculated figures for a documented generator topology, not a manufacturer's bill of materials, and they cannot be applied to every wind turbine.
02D-G · Literature range
NdFeB per applicable permanent-magnet MRI scanner
Apply only to MRI systems with NdFeB permanent magnets. Superconducting MRI systems must not be included by default.
03A-M · Published design/BOM case
NdFeB in the 1.25-MW design studied
The design case is not a market average for industrial drives of other power ratings, designs or manufacturers.NdFeB in purchase assessment
Appearance and magnetic force are insufficient for identification. For ES Metall's purchase assessment, record the design, origin, condition, foreign materials, net quantity and available documents.
Block and rectangular magnetsWhen offering loose block and rectangular magnets or cleanly separated lots for sale, state the dimensions, number of items, total weight, coating and origin.→
Ring magnetsRing magnets and magnets with a bore are assessed by their outer and inner diameters, height, coating and documented material family.→Disc and cylinder magnetsDisc 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.→
Segment and arc magnetsRotor segments and arc magnets are used in motors and generators. Loose segments and complete rotors require different system boundaries.→HDD / actuator magnet assembliesDescribe 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.→Broken magnets & production scrapBroken 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.→Rare earths in magnets
Neodymium, praseodymium, dysprosium, terbium and samarium are explained here in terms of their functions in NdFeB or SmCo systems. Detailed information on each element remains within its dedicated specialist portal.
How to prepare your sales enquiry
Whether ES Metall can purchase the material depends on its type, quantity, condition and assessability. These details allow us to agree the appropriate next step.
State the magnet type, material form, origin and previous application.
Match overview and detail photographs, labels, CoA, analysis or SDS to the material.
Record the net weight, number of items, coating, corrosion, moisture and foreign materials.
Material identity, assessability and the potential next steps are considered individually.
Do not send strong magnets, powders, sludges or unidentified substances without prior agreement.
NdFeB research with sources
The specialist pages cover wind-turbine models, electric and hybrid vehicles, robotics and other applications. Measurements, manufacturer statements, calculations and literature figures remain distinct, and uncertainties are clearly identified.
Applies to the specific model or component studied.
The design is documented, and the quantity was calculated from a documented factor.
Do not treat this as a published bill of materials for the specific model.
Missing information is not replaced with estimates.
