1J50 Fe-Ni Soft Magnetic Alloy Expanded Metal Mesh combines the material’s soft magnetic properties with the structural advantages of mesh, mainly used for:
– **Electromagnetic shielding ventilation components**: Utilizes high magnetic permeability to shield electromagnetic interference while the mesh structure enables equipment ventilation and heat dissipation (e.g., electronic cabinets, transformer enclosures).
– **Lightweight magnetic circuit supports**: Serves as a support framework for iron cores or magnetic components, reducing weight while maintaining magnetic permeability, applied in relays and transformers.
– **Magnetic field homogenization components**: Guides magnetic field distribution through the mesh structure to enhance the uniformity and sensitivity of sensors and magnetic amplifiers.
– **Anti-interference filtering structures**: Functions as a filtering mesh in high-frequency circuits to suppress electromagnetic noise, integrating structural strength and magnetic performance.
