Product Manufacturing Process

The manufacturing process for nanocrystalline cores involves the rapid solidification of molten metal alloys containing iron, silicon, boron, and other elements. This process produces a fine crystalline structure with grain sizes ranging from 10 to 100 nanometers. The material undergoes heat treatment for controlled crystallization, optimizing magnetic properties. During production, strict quality control measures are implemented to ensure high permeability, low coercivity, and minimal core losses. Ferrite cores, composed of iron oxide combined with materials like manganese, zinc, or nickel, undergo a sintering process at high temperatures. This ceramic process yields high resistivity and cost-effectiveness, making ferrite cores suitable for a broad frequency range but less efficient compared to nanocrystalline cores.
