硅钢是电力变压器和电子变压器用量最多、使用历史最久的铁芯材料。硅钢的技术性能比较稳定，环境适应性能强，受温度、机械应力的变化以及冲击等的影响小，饱和磁通密度高，损耗小。变压器常用的硅钢有取向冷轧硅钢和无取向冷轧硅钢。
Silicon steel dosage of power transformer and electronic transformer is the most core material, use the oldest. Silicon steel technical performance is stable, environmental adaptation performance is strong, affected by the change of temperature, mechanical stress and impact is small, the influence of high saturation magnetic flux density, low loss. Transformer commonly used silicon steel with and without orientation orientation cold-rolled silicon steel cold-rolled silicon steel.
　　它们大多用于工频变压器中。近十多年中，开发了多种特殊硅钢和薄带硅钢，已被用于中高频变压器中。硅钢的用途和性能由于受到近年来快速发展的铁基非晶合金和纳米晶合金的挑战，又兴起了新的研究开发高潮，在技术性能、生产工艺技术上都有新的发展和进步。另外，硅钢材料适合规模化生产，这也是能够被广泛大量使用的重要因素。

They are mostly used in power frequency transformer. For nearly 10 years, has developed a variety of special and thin silicon steel, silicon steel has been used in high frequency transformer in. The purpose and performance of silicon steel, due to the rapid development in recent years, iron base amorphous alloy and the challenge of nanocrystalline alloy, and the rise of a new research and development, on the technical performance, production technology has the new development and progress. In addition, the silicon steel material is suitable for mass production, it is also can widely use a lot of important factor.
　　1、铁损低，这是硅钢片质量的最重要指标。各国都根据铁损值划分牌号，铁损愈低，牌号愈高。
1, low iron loss, this is the most important indicator of the quality of silicon steel sheet. All countries according to the division iron loss value brands, lower iron loss, the higher the brand.
　　2、较强磁场下磁感应强度高，这使电机和变压器的铁芯体积与重量减小，节约硅钢片、铜线和绝缘材料等。
2, strong magnetic field of magnetic induction intensity is high, this makes the motor and transformer core size and weight is reduced, saving the silicon steel sheet, copper wire and insulation material.
　　3、表面光滑、平整和厚度均匀，可以提高铁芯的填充系数。
3, the surface is smooth, smooth and uniform thickness, can improve the filling coefficient of iron core.
　　4、冲片性好，对制造微型、小型电动机更为重要。
4, stampings, used in fabrication of micro and small motors are more important.
　　5、表面绝缘膜的附着性和焊接性良好，能防蚀和改善冲片性。
5, surface insulation film adhesion and good weldability, corrosion and improve plate.
