This study describes a methodology to evaluate the sustainability of a bimetallic component putting emphasis on energy, material, and component efficiencies. Energy efficiency deals with the direct energy consumptions while manufacturing a bimetallic component. Material efficiency deals with the yield, lightweighting, cost, and CO 2 footprint of primary material production of the materials used in the component. Component efficiency deals with the degree of alteration of functional properties of the component (surface-finish, strength, and alike). Numerical examples are described based on a case of a bimetallic component made of commercially pure Aluminum and Titanium. It is found that the material efficiency is effective than the energy efficiency in enhancing the sustainability, whereas enhancing component efficiency remains a challenge. The outcomes of this study will help make informed decisions in developing sustainable bimetallic components.
