Product Manufacturing Process
Nanocrystalline cores are manufactured through a rapid cooling process that produces nanometer-sized grains within the material. Typically made from iron-based alloys mixed with elements like silicon and boron, these materials undergo precise alloying and melting procedures. The rapid cooling, often achieved through a melt-spinning technique, solidifies the alloy into thin ribbons, maintaining their nanocrystalline structure. Subsequent heat treatments may be applied to enhance their magnetic properties. This process ensures high permeability, low coercivity, and excellent thermal stability, making the nanocrystalline cores ideal for metering applications.
