27Q120 High Magnetic Induction Grain-Oriented Silicon Steel
Model: 27Q120 | Material: Hi-B (with MnS and AlN inhibitors) | Thickness: 0.27mm
Product Summary
Our 27Q120 is a high magnetic induction grain-oriented silicon steel (Hi-B) designed for small and medium transformer cores and electrical equipment. With a nominal thickness of 0.27mm and iron loss (P₁.₇/₅₀) ≤ 1.20 W/kg, it offers an optimal balance of magnetic performance and core loss. Manufactured with strict quality control, this grade is widely used in transformer manufacturing, contributing to energy-efficient and reliable electrical equipment.
Key Selling Points
- High magnetic induction: Hi-B grade provides higher permeability, reducing the size of transformer cores for the same capacity.
- Low iron loss: P₁.₇/₅₀ ≤ 1.20 W/kg minimizes no-load losses, improving energy efficiency of transformers.
- Precise thickness: 0.27mm thickness ensures consistent magnetic properties and good stackability.
- Inhibitor-controlled: Contains MnS and AlN for controlled grain growth, resulting in low core loss.
- Field-tested: Used by WEG in Brazil for over 10 years, demonstrating reliability in real-world applications.
- Customizable: Available in various widths and coatings to meet specific manufacturing needs.

Models and Options
This product is available in standard coil form. Please contact us for available widths and coating types. We can also process to specific slitting or shearing requirements.
Materials and Structure
The steel is primarily iron (Fe) with silicon (Si) added at about 3%, along with aluminum and manganese. The presence of inhibitors (MnS, AlN) ensures a sharp Goss texture, which is key for high magnetic induction and low iron loss.
Applications
Designed for small and medium transformer cores and electrical equipment, suitable for:
- Distribution transformers
- Power transformers (up to certain ratings)
- Special engineering transformers
- Reactors and other inductive components
Case Study
WEG Brazil (Client for 10+ years): WEG has applied our oriented silicon steel in the local manufacturing of power and distribution transformers. This long-term partnership supports WEG's production in Brazil, meeting local grid energy efficiency standards and supporting Latin America's energy transition.
