Integration of two metallurgically distinct materials (bimetallic) is an inevitable advancement in the automotive andmarine field. In this context, this study investigates the fabrication, characterization, and properties of solid–liquid compoundcast aluminum alloy AA5052 and ferrous alloy (mild steel and galvanized iron) based bimetallic materials. Microstructuralevolution, microhardness, and tensile strength of the developed bimetallic material are investigated. The results show thatthe formation of cracks at the interface in AA5052/Mild Steel caused the joint failure in the course of preliminary testing. InAA5052/Galvanized Iron, the growth of intermetallics at the oxide-free steel surface results in a shear strength of 19.9 MPa. XRD analysis attests to the presence of brittle intermetallics and Al bond at the interface of AA5052/Galvanized Iron bimetallicmaterial, which in turn confirms the development of a metallurgical.
