Automotive programs punish magnetic drift. Vibration, thermal cycling from -40°C to 150°C+, and a service life measured in decades expose weak grades and weak suppliers fast. We engineer magnets and assemblies for EV auxiliary drives, steering, braking and sensing — with the batch traceability your quality team expects.
Automotive qualification failures we help customers avoid — before they reach your validation lab.
A motor or sensor must perform the same in year ten as in year one. Grades selected without coercivity margin lose flux permanently under thermal cycling — and the failure appears long after SOP.
-40°C cold starts to 150°C+ under-hood operation, plus constant vibration. Coatings crack, adhesives fatigue, and magnetic properties drift if material and assembly choices aren't made for this environment.
Humidity, salt spray and chemical exposure attack unprotected NdFeB. A corroded magnet in a steering or braking system is not a quality issue — it's a safety issue.
Your quality team needs to trace every part back to its material batch. Suppliers who can't provide batch-level records and inspection data create audit risk you don't need.
Application-first engineering — we start from your operating conditions, not our catalog.
We select high-coercivity grades (SH/UH/EH series) with aging margin calculated for your worst-case temperature profile — not just nominal room-temperature performance.
NiCuNi, epoxy and zinc coatings selected per your corrosion requirements, with salt spray and pressure cooker (PCT/HAST) test data available for qualification files.
Rotor and sensor sub-assemblies with automotive-suitable adhesives and mechanical retention designs, so magnets stay where your simulation put them.
Every shipment links to material batch records, dimensional inspection data and flux measurements. FAI reports available for new program launches.
Everything below can be customized to your drawings and specifications.
