Note : 1. Values above were measured according to the method JIS C 2550 (2000).
2. Test samples were consisted of half the strips sheared parallel and half sheared transverse to the rolling direction.
3. W15/50 indicates the core loss at 50Hz and 1.5T. B50 indicates the magnetic flux density at 5000A/m.
4. The specimens were tested as sheared.
5. The values shown above are the typical ones, not for guarantee.
