SECONDARY ALUMINUM ALLOYS IN TRANSPORTATION
Adelina Miteva Aluminum and its alloys are gaining significant attention due to their high strength-to-weight ratio, corrosion resistance, and recyclability. this study explores the use of secondary aluminum alloys in current and potential Transportation applications. secondary aluminum production involves recycling aluminum scrap, significantly reducing environmental impact and energy consumption. Research shows that recycled aluminum is 92 percent more energy-efficient than primary production, making it a sustainable alternative.
In transportation, secondary aluminum alloys are used in automotive components, aircraft structures, and railway systems. These applications benefit from the material`s lightweight nature, improving fuel efficiency and reducing greenhouse gas emissions. Additionally, the durability and cost-effectiveness of recycled aluminum make it appealing for widespread use. This report analyzes the mechanical and physical properties of secondary aluminum alloys, comparing them with primary aluminum to highlight benefits and trade-offs. It addresses recycling challenges like contamination and alloying element losses, proposing advanced techniques to overcome these issues. Future work in this field will focus on innovative recycling technologies and optimizing alloy compositions to meet the transportation industry`s evolving demands. The findings emphasize the role of secondary aluminum alloys in promoting sustainable development and advancing transportation technology. вторични алуминиеви сплави транспортна индустрия рециклиране на алуминий енергийна ефективност алуминиев скрап устойчиви материали индустриални приложения въздействие върху околната среда свойства на материалите бъдещи разработки.secondary alumiAdelina Miteva BIBLIOGRAPHY [1] Schlesinger, M.
