铁基非晶态合金薄带正日益广泛地被电力变压器制造厂家用作铁芯材料，它可比硅钢片铁芯的铁损减少２／３，节能效益显著。但若含有即使是很微量（０．０１％）的Ａｌ和Ｔｉ之类杂质时，也会使其软磁特性大为降低．因此，要求使用高纯度原料生产，以致使生产成本大为提高。发现 Iron-based amorphous alloy ribbons are increasingly being used as core materials by power transformer manufacturers to reduce core loss by as much as two-thirds compared to silicon steel cores, resulting in significant energy savings. However, if impurities such as Al and Ti are contained in a very small amount (0.01%), their soft magnetic properties are greatly reduced. Therefore, the production of high-purity raw materials is required so that the production costs are greatly increased. Find
