Our Products Details
Nano crystalline soft magnetic materials represent a breakthrough in modern magnetic core technology. Comprising 82% iron, with the remainder made up of elements like silicon, boron, niobium, copper, carbon, molybdenum, and nickel, these cores outperform traditional materials such as silicon steel and permalloy. Iron-based nano crystalline alloys offer superior permeability and cost efficiency, making them the ideal choice for precision current transformers with accuracy classes of 0.2, 0.2s, and 0.1.
Key Benefits of Nano Crystalline Alloy Cores:
- High Permeability: Reduced current measurement errors.
- High Saturation Induction: Smaller, lighter core designs.
- Thermal Stability: Reliable operation in extreme temperatures from -55°C to 130°C.
- Low ISF: Instrument Security Factor less than 5, ensuring top performance and reliability across a broad frequency range.
