Product Manufacturing Process

Nanocrystalline materials are typically manufactured using rapid solidification processes such as melt spinning followed by annealing. The process starts with a molten alloy that is rapidly cooled on a rotating wheel to produce thin ribbons. These ribbons are then annealed at specific temperatures to develop their nanocrystalline structure, which is essential for optimizing magnetic properties. Studies have shown that controlling the annealing temperature and time can significantly impact the material's grain size and distribution, thereby influencing its magnetic performance and thermal stability.
