Material Characteristics & Technical Analysis
Other shields are typically made from high magnetic permeability 1J85 material, which possesses superior magnetic permeability and extremely low coercivity. In weak magnetic fields, it exhibits excellent shielding and anti-interference capabilities. It is mainly used for anti-interference protection of various equipment and electronic components in strong magnetic environments, widely applied across transformers, sensors, and diverse electrical apparatus.
1J85 material is a specialized high magnetic permeability alloy, usually composed of nickel and iron, featuring exceptionally high permeability and low coercive force. This allows it to excel at shielding weak magnetic fields and drastically reducing electromagnetic interference. These shielding covers are engineered not only to effectively block external magnetic fields, but also to prevent magnetic radiation generated by internal equipment from escaping and interfering with nearby devices.
These shields are manufactured via precision die stamping, ensuring exact dimensions and reliable consistency across production batches. Following high-temperature heat treatment, the magnetic shielding efficiency of the shielding cover is further optimized. This sophisticated production process enhances both the mechanical structural strength and its operational durability in complex electromagnetic environments.
In practical applications, other shields protect highly sensitive electronic components such as precision sensors, signal processors, and high-frequency communication hardware to guarantee uncompromised performance under strong magnetic influences. Furthermore, they are extensively installed in power units like transformers and inductors to restrain magnetic field leakage, notably enhancing operational efficiency and overall equipment safety.
