Materials & Grades
Choose by frequency, flux density and loss target. These are the grades we use most; other grades and gauges are available on request.
| Material | Grades | Thickness | Typical use |
|---|---|---|---|
| Silicon steel (GOES) | 23Q110 · 27Q100 · 30Q120 | 0.23–0.30 mm | Low core loss, high flux, 50/60 Hz |
| Silicon steel (NGOES) | 50W470 · 35W300 | 0.35–0.50 mm | Lower cost, general purpose |
| Nanocrystalline | 1K107 (FeCuNbSiB) | 18–30 µm | µi up to 100k+, lowest loss above 10 kHz |
| Amorphous | 2605SA1 (FeSiB) | 25 µm | Bs ≈ 1.56 T, low no-load loss |
| Ferrite MnZn (power) | TC40 · TC44 · TC47 ≈ PC40 / PC44 / PC47 | — | 100 kHz – 1 MHz, power conversion |
| Ferrite MnZn (high-freq) | TC90 · TC95 · TC96 | — | High-frequency, low loss (server/EV power) |
| Ferrite NiZn | High-frequency grade | — | 1–500 MHz, EMI suppression |
Frequency first
50/60 Hz → silicon steel. 10–100 kHz → nanocrystalline. 100 kHz–MHz → ferrite.
Flux and DC bias
Silicon steel Bs ≈ 2.0 T, amorphous 1.56 T, nanocrystalline 1.2 T, ferrite 0.4–0.5 T.
Loss vs cost
Thinner, higher-grade strip lowers loss but raises cost — balance against energy saved.
