详细说明
非晶是一种新型软磁合金材料，它采用国际先进的超急冷技术将熔融金属以1*106万℃/S的速度直接冷却，形成厚度为15--35μm的非晶体薄带，得到原子排列组合上具有短程有序，长程无序特点的非晶合金组织。硅钢具有严谨的晶体结构，而非晶合金原子排列的无序性使其具有许多独特的性能。如优异的磁性、耐蚀性、耐磨性、高硬度、高强度、高电阻率等。
Amorphous alloy is a new soft magnetic material. It is produced through the advanced technology of rapid solidification of molten metal at a cooling rate of about a million ℃/sec. During this process the metal is rapidly quenched as a form of ribbon with 15--35μm thickness, and the micro-structure of the alloy is the amorphous due to the high quenching rate.
铁基非晶带材具有超微细晶粒结构，很高的初始磁导率、高饱和磁感、低铁损和优良的稳定性，可以替代硅钢、坡莫合金和铁氧体，广泛应用于精度要求高、稳定性要求高的电子产品中。
Iron-based amorphous ribbon has many advantages, like good permeability, high saturate induction, high electrical resistivity, high density, low loss and good stability. It can replace the materials of silicon steel, permalloy and ferrite. It is widely used in electronics products that high accuracy and good stability are the most required.
