The main study objective is to make a composite material based on an aluminum alloy with increased strength and plastic properties compared to aluminum alloys traditionally used in mechanical engineering. The tasks to which the paper is devoted are to develop a technology for making a specified composite material and to study its basic mechanical properties. Comparative analysis at the stage of determining the relevance of the work, mathematical calculation of explosion welding parameters to obtain a composite and testing on a tensile machine in order to obtain values of strength and plastic parameters are used as research methods. The novelty of the work is in the application of technological operations that give the material a set of properties that it did not possess in its original state. The study results show that this area is in demand both in Russia and abroad; new improved aluminum alloys are made; the most relevant way to improve properties is to make a composite material. A composite is obtained, which has a 40% higher tensile strength and 3% higher elongation compared to the starting material. When compared with the traditionally used AMg5M alloy, the developed composite has an advantage of 35% in strength parameters and 70% in plasticity. Also, this material has an advantage in strength and ductility over 1565h MU alloy.
