As an important indicator of quality, each country divides the grade by the iron loss value. The lower the iron loss, the higher the grade and the higher the quality.B. High magnetic induction strength. Under the same magnetic field, the silicon steel sheet with high magnetic sensitivity can be obtained. The volume and weight of the iron core of the motor or transformer made by it are relatively small, which can save silicon steel sheet, copper wire and insulating materials, etc.C. High stacking coefficient. The surface of the silicon steel sheet is smooth, flat and uniform in thickness, which improves the stacking coefficient of the iron core.D. Good punching property. This is more important for manufacturing small and micro motor iron cores.E. The surface has good adhesion and weldability to the insulating film.

電工鋼硅鋼片1882~1995年主要是熱軋硅鋼的發(fā)展階段。1903年美國(guó)和德國(guó)首先開始生產(chǎn)熱軋硅鋼。1905年美國(guó)（英國(guó)在1906年）已經(jīng)大規(guī)模生產(chǎn)，在很短的時(shí)間內(nèi)全部替代了普通低碳鋼板制造電機(jī)和變壓器。由于冷軋無取向硅鋼的磁感、安徽銅陵當(dāng)?shù)罔F損、安徽銅陵當(dāng)?shù)貨_剪加工性、安徽銅陵當(dāng)?shù)乇砻尜|(zhì)量和絕緣涂層等質(zhì)量性能都大大優(yōu)于熱軋硅鋼，并且熱軋產(chǎn)品不能成卷生產(chǎn)，降低了沖片效率，60年代主要的工業(yè)發(fā)達(dá) 都陸續(xù)停止生產(chǎn)熱軋硅鋼。1957年，前西德阿什姆斯在實(shí)驗(yàn)室內(nèi)生產(chǎn)出了雙取向硅鋼片（立方織構(gòu)的硅鋼）。沿軋向和橫向都有很高的磁性，但尚在實(shí)驗(yàn)室階段，未投入工業(yè)生產(chǎn)。
