27Q105 Hi-B Oriented Silicon Steel for Transformer Cores

The 27Q105 is a high magnetic induction grain-oriented silicon steel (Hi-B) designed for power transformer cores. With a thickness of 0.27mm, low iron loss of ≤1.05 W/kg at 1.7T/50Hz, and high magnetic flux density (B8 ≥1.88T), this material enhances transformer efficiency and reduces energy losses.

Key Selling Points

• Low Iron Loss: Achieves ≤1.05 W/kg (P1.7/50), reducing core losses and improving transformer energy efficiency.
• High Magnetic Flux Density: B8 ≥1.88T ensures compact core designs and higher power output.
• Optimized Thickness: 0.27mm thickness minimizes eddy current losses, ideal for high-frequency applications.
• Proven Performance: The material has been used in transformer manufacturing for over 10 years, with stable operation verified by leading manufacturers.
