FREQUENTLY ASKED QUESTIONS
What is the difference between Oriented and Non-Oriented silicon steel?
Oriented silicon steel has a preferred crystallographic orientation and is used primarily for transformers where the magnetic field direction is fixed. Non-oriented silicon steel has random grain orientation, making it ideal for rotating machinery like motors and generators where the magnetic field direction varies.
What thicknesses are available for your electrical steel products?
Our products range from ultra-thin 0.2mm for medium frequency applications to 0.65mm for common industrial uses, including standard options of 0.23mm, 0.27mm, 0.3mm, 0.35mm, and 0.5mm.
What are the advantages of the High Induction series?
The High Induction series (SQG) offers superior magnetic permeability, allowing for higher magnetic flux density. This results in more efficient equipment designs and reduced core losses in transformer applications.
When should I use the Stress-relief annealing series?
The Stress-relief annealing series (SWR) is specifically designed for applications where mechanical stresses during fabrication need to be minimized to maintain optimal magnetic properties, often used in precision motor cores.
What applications are best suited for the Medium Frequency series?
The Medium Frequency series (e.g., 20SW1500) is optimized for higher frequency operations, providing lower eddy current losses, making it perfect for high-speed motors and specialized high-frequency transformers.
Do you offer domain-refined products?
Yes, our Oriented steel includes Domain Refined High Induction types (SQGD) which utilize specialized surface treatments to further reduce iron loss, achieving maximum energy efficiency in high-end power transformers.
