Practical magnet guide
Guides to applications, identification and NdFeB fundamentals
Eight guides help you assess magnet shapes, assemblies, motors, hard-drive magnets and wind-turbine material. Technical details are explained together with their limitations and relevant specialist sources.
Eight specialist guides
Identify magnets, establish their origin and prepare an enquiry
Magnet assemblies & rotors
Submit an enquiry for rotors, motor assemblies and magnet-containing components, stating the component, magnet type, dismantling status and material status.
→02NdFeB fundamentals
What NdFeB means, how rare-earth magnet materials differ and which material information genuinely helps when enquiring about selling material to ES Metall.
→03NdFeB or SmCo
Document and analyse neodymium-iron-boron and samarium-cobalt separately as different rare-earth magnet materials.
→04Identify magnets
Combine markings, data sheets, component context, photographs and suitable analysis – without risky breakage, heat or pull tests.
→05Applications & origin
Motors, generators, data-storage devices, electronics and audio equipment as possible sources – not as conclusive evidence of material or value.
→06HDD magnets
Submit an enquiry for magnets and voice-coil assemblies from hard drives, stating the status of any data-bearing media, dismantling route, attached materials and material data.
→07Electric motors & servo motors
Assess motors, rotors and magnet segments by motor type, component condition, magnet data, attached materials and origin.
→08Wind-turbine magnets
Assess generator and decommissioning material from wind turbines without assuming fixed magnet masses, grades or HREE content.
