Product Manufacturing Process
The manufacturing process of nanocrystalline cores involves several critical steps. Initially, a ribbon of amorphous metal is produced through rapid solidification from the molten state, typically involving a melt spinning process. This ribbon is then wound into the core shape followed by a process of annealing under controlled conditions to induce nanocrystalline structures. Heat treatment is performed in a magnetic field to enhance magnetic properties such as permeability and reduce core losses. The entire process is carefully controlled to ensure consistent quality and optimal performance parameters. The outcome is a core with superior magnetic properties, crucial for high-efficiency, low-loss applications.
Product Application Scenarios
Nanocrystalline cores are widely used in various high-frequency and high-efficiency applications due to their superior magnetic properties. In switch-mode power supplies (SMPS), these cores enable higher efficiency and smaller size due to their low core losses and high permeability. In applications like electric vehicle chargers and renewable energy systems, the high saturation flux density allows for more compact transformer designs. Additionally, they are crucial in medical equipment for high-frequency transformers due to their excellent performance in minimizing electromagnetic interference (EMI). In rail transit power supplies and charging piles, their robust performance at wide temperature ranges ensures reliability and efficiency in demanding environments.
