Recyclable Aluminium Structural Casting Alloy (RASCAL)

铝合金结构铸件是未来低碳汽车车身结构的重要组成部分。它们目前是由原铝制成，使用的合金成分不够延展性或与报废车辆的闭路回收不兼容。布鲁内尔大学的研究表明，一种新的合金成分可以满足捷豹路虎对结构铸件的机械性能、使用自穿孔铆钉的接合性以及75%的可回收含量(包括工艺和消费后废料)方面的要求。这个为期24个月的项目将使布鲁内尔大学能够开发用于新型合金结构BIW(白车身)应用的高压铸件，并将其作为回收废料水平的函数在工业规模上进行演示。其目标是建立一个完全基于英国的供应链，并在汽车生产和使用方面大幅减少二氧化碳排放。

Structural aluminium alloy castings are an essential part of future Low Carbon Vehicle (LCV) body structures. They are presently made from primary aluminium using alloy compositions that are not sufficiently ductile or compatible with the closed loop recycling of end of life vehicles. Research at Brunel University has demonstrated that a novel alloy composition can meet the Jaguar Land Rover requirements for structural castings in terms of mechanical properties, joinability using self-piercing rivets, and a recycled content of 75% including both process and post consumer scrap. The 24 month project will enable high pressure diecastings for structural BIW (Body in White) applications of the new alloy to be developed at Brunel University and demonstrated on an industrial scale as a function of recycled scrap level. The goal is both a fully UK-based supply chain and significant CO2 savings in vehicle production and use.
