Fe-Ni alloy 1J30/1J31/1J32 Expanded Metal Mesh

1J31 wire mesh : Stands out for its temperature stability (magnetic performance fluctuates <10% in -50°C to +150°C) and dimensional accuracy, crucial for sensors and miniature devices sensitive to environmental changes.

1J32 metal mesh : Excels in ultra-low coercivity and high maximum permeability, catering to high-precision scenarios like aerospace-grade shielding and high-frequency signal processing where minimal energy loss is essential.

1J30 alloy mesh: Emphasizes rapid magnetic saturation in low fields, making it ideal for components requiring high initial permeability, such as low-voltage transformers and relays.
