Magnetic Shielding at Low Frequencies: Application for an Aluminum/Steel Composite Elaborated by Accumulative Roll Bonding

An IF steel/Al6061 composite elaborated by Accumulative Roll Bonding at room temperature is proposed for shielding effectiveness applications. The obtained composite is lighter than the copper and the steel with a density of 3–4.5. In the earlier rollings, a multilayered composite is developed which is in favor of strength but not of shielding. On the contrary, after 3 roll bondings, fragments of IF steel appear in the Al6061 matrix and drastically reduce strength but improve shielding.
