This study examines the possibility of recycling aluminum scrap from military equipment destroyed due to warfare in Ukraine, which has led to significant environmental and economic challenges. The accumulation of damaged equipment in open areas poses a threat of environmental pollution due to metal corrosion, which causes the release of hazardous substances into the soil, water bodies, and atmosphere. However, despite these issues, such equipment also has significant untapped economic potential, as it can be recycled into secondary materials for the production of new modern products. The study revealed that the obtained aluminum alloy is close in its chemical composition to commercially available alloys such as 1925 and V95, which increases its feasibility for use in new cast products with adequate mechanical properties. The determined mechanical properties of the alloy, including its strength (up to 140 MPa) and elongation (2.42%), confirm the alloy’s potential for further use in industry, particularly in structures requiring high mechanical properties. Specifically, the obtained alloy can be applied for the manufacture of structural elements that require high specific strength and corrosion resistance, such as cast engine components, housing parts, and other structural elements. The proposed technology for recycling aluminum scrap ensures efficient use of secondary resources with minimal environmental impact, which is an important aspect of the sustainable development of the metallurgical industry. The study confirmed the possibility ofobtaining an aluminum alloy that is close in its chemical composition and mechanical properties to industrially used alloys such as 1925 and V95. Thus, the research results can serve as a basis for further improvement of aluminum recycling technologies and their implementation into practice. The use of secondary aluminum alloys in production will not only allow for reducing the environmental footprint of the metallurgical industry but also contribute to economic development, optimization of resource consumption, and reduction of dependence on primary raw materials.
