Ultra-Thin Non-Oriented & Grain-Oriented Electrical Steel: Precision Solutions for High-Frequency Applications.
Engineered for Efficiency: Ultra-Thin Silicon Steel Innovations
Optimized for high-frequency motors and compact transformers, our ultra-thin electrical steel combines low core losses (≤0.85 W/kg) and high magnetic saturation (≥1.85T). Available in both grain-oriented (GOES) and non-oriented (NOES) variants, these sheets minimize eddy current losses in devices operating at 400Hz–10kHz.
Key Differentiators:
- Thin Gauges: 0.10mm–0.50mm thickness (±0.01mm tolerance)
- Isotropic vs. Anisotropic: NOES for motors, GOES for transformers
- Global Standards: ASTM A977, JIS C 2553, EN 10107
