Shielding blocks are widely used to protect sensitive electronic components in defense and medical equipment. In many circumstances, acquiring shielding effectiveness is insufficient, with shielding effectiveness having higher priority if the material possesses mechanical characteristics. To achieve the required electromagnetic shielding effectiveness and mechanical properties such as tensile strength and hardness, a laminate sheet with Al6061 material and micro absorbing materials such as MNZC ferrite rubber composite, Ca-NiTi hexaferrite composites, and Carbonyl iron is preferred in the current work. The total work organized as•Selection of the aluminum metal matrix and micro absorbing material.•Finding the electrical parameters using the vector network analyzer (VNA) using Transmission/Reflection method.•The shielding performance was evaluated for different laminate thicknesses at the X-band.•The material mentioned above can be used as a shielding building block in aeronautical applications and near sensitive medical equipment.
