Components & Materials for Automotive and New Energy Vehicle Systems.
Our capabilities evolved alongside automotive electrification — from motor magnets and magnetic assemblies to precision metal components and advanced electronic materials.
Typical Applications
Where our magnets ride:
| Application | Typical Material | What Matters |
|---|---|---|
| EPS & steering motors | NdFeB arc segments, high Hc grades | Demag resistance, consistency |
| Seat & mirror actuators | Bonded NdFeB rings | Low cost, quiet operation |
| Wheel speed sensors (ABS) | NdFeB multipole rings | Pole accuracy, temp stability |
| Water / oil pump motors | NdFeB arcs, overmolded rotors | Sealing, corrosion resistance |
| Transmission sensors | SmCo 2:17 | High temp stability |
| EV auxiliary motors | NdFeB rotor assemblies | Torque density, efficiency |
What We Supply to Automotive OEMs
- ✓High-coercivity grades — N38SH–N48SH and HRE-free high-temp grades that resist demagnetization in demanding duty cycles
- ✓Automotive coating systems — Ni-Cu-Ni tested to 1000-hour salt spray; epoxy and zinc options for specific environments
- ✓Overmolded rotors — insert-molded magnet rotors with stainless shafts — sealed, balanced, and ready for automated assembly
- ✓PPAP-style documentation — dimensional reports, material certs, flux and BH-curve data, capability studies on request
- ✓Traceability — lot-level material traceability through the entire production chain
- ✓IATF 16949 certificate — our quality management system is certified to IATF 16949 alongside ISO 9001 and ISO 14001
Why Automotive OEMs Choose China Empire
A careful, engineering-first supplier for automotive programs.
Documentation That Passes Audits
Material certs, PPAP-style submissions, capability data, and full traceability — the paperwork your quality team expects.
Temperature-Verified Designs
BH-curve verification at operating temperature, not just room temperature. Demag margins calculated for worst-case duty.
Cost Engineering
Grade substitution studies that keep performance while trimming rare earth content — significant savings at automotive volumes.
