Product Manufacturing Process

The manufacturing process of nanocrystalline cores involves a series of meticulously controlled steps. Initially, a molten alloy consisting of iron, silicon, boron, and minor additions of copper and nickel is prepared. This molten alloy undergoes rapid solidification via melt spinning, resulting in thin metallic ribbons. Subsequently, these ribbons are subjected to a precise annealing process, where they are heated to a specific temperature and then cooled at a controlled rate. This annealing fosters the formation of a nanometer-scale crystalline structure within an amorphous matrix. This unique combination of nanocrystalline and amorphous phases imparts superior magnetic properties, such as high permeability, low coercivity, and excellent thermal stability, to the final product.
