Frequently Asked Questions
Our Crgo mother coils are in stock and ready to ship. Crgo slit coils take 3-5 days to process.
High-frequency transformers → M4/M5 preferred (low loss at high frequencies)
Giant power transformers → M3 grade is preferred (optimal cost-effectiveness)
Aerospace equipment → Hi-B grade recommended (fatigue resistance increased by 50%)
Laser-treated CRGO oriented silicon steel reduces iron loss and improves magnetic domain refinement for higher efficiency, while non-laser versions have larger magnetic domains and higher energy losses.
