Product Description
Oriented silicon steel is a state-of-the-art low-carbon silicon iron alloy meticulously crafted with 0.5% to 4.5% silicon. Renowned for its astonishing high permeability, this superior material drastically reduces Joule loss in power equipment, thus enhancing efficiency and offering extraordinary energy-saving advantages. Its exceptional low iron loss combined with a high resistance coefficient makes it the ultimate choice for cutting-edge, high-performance applications.
We supply a wide spectrum of grades to cater to your every need: B30P120, B30P105, B30R100, 27QG120, 27QG100, 23Q110, 23QG100, 23QG095, 23RK090, 23RK085, 23QG085, 23RK085, 23QG085, 23RK080, 23RK075, B23R070, 20QG085, 20RK080, 20RK075, B20R070, B20R065,M0H,M1H,M2,M3,M4,M5. Each grade is engineered to provide superior performance and reliability.
