Iron-Based Amorphous Alloy Ribbons
Iron-Based Amorphous Alloy Ribbons
Iron-based amorphous alloy ribbon is the base raw material for manufacturing high-performance transformer and motor cores. It is formed in a single step from molten steel into thin strips approximately 25-30 micrometers thick using rapid quenching technology. Its atomic arrangement presents a disordered amorphous structure (known as 'metallic glass'). This unique structure gives the material an extremely narrow hysteresis loop, high permeability, and low coercivity, making its resistivity 2-3 times higher than traditional silicon steel, thereby significantly reducing eddy current losses. As a core upstream material, it is key to achieving 'ultra-low no-load loss' and 'high energy efficiency' in downstream products.
