Product Manufacturing Process

Nanocrystalline cores are manufactured using a precise process that starts with the selection of high-quality iron-based alloys. These alloys include compositions such as Fe-Si-B, Fe-Ni, and Fe-Co. The manufacturing process involves rapid solidification, followed by annealing to achieve a nanoscale crystalline structure. Rapid solidification is performed by cooling the molten alloy at an extremely high rate, creating an amorphous structure initially. Once solidified, the material undergoes annealing at controlled temperatures to form nanocrystalline grains embedded within the amorphous matrix. This unique microstructure provides the exceptional magnetic properties characteristic of nanocrystalline cores.

Product Application Scenarios

Nanocrystalline cores find extensive application in various electrical and electronic systems. Due to their high permeability, low core losses, and high saturation magnetization, they are ideal for use in transformers, inductors, magnetic amplifiers, current transformers, and chokes. In transformers, these cores enhance efficiency and reduce energy losses, especially in high-frequency applications like switch-mode power supplies. Inductors benefit from the high permeability and low losses, making them efficient for power electronics, filtering, and energy storage. Magnetic amplifiers leverage the high saturation magnetization for compact, efficient designs, while current transformers rely on the precision and stability of nanocrystalline cores for accurate current sensing and measurement. Chokes utilize the low core losses and high permeability to effectively block high-frequency noise, crucial for EMI and RFI suppression.
