Development of an A356 type alloy produced from recycled cast aluminum wheels

Eccomelt是House of Metals的子公司，通过清洁和破碎的专利工艺，从回收的铝轮辋中生产和销售铝合金。这种产品被称为Eccomelt356.2，其成分与A356.2铸锭非常相似，通常由铸造厂用原铝稀释形成A356.2。为了增加其市场份额并为Eccomelt356.2找到新的市场机会，金属之家希望开发铸造实践，以提高产品在熔融金属炉料中的利用率，而不影响全部或部分由Eccomelt356.2制成的铸造产品的机械性能。该项目的目标是研究以下参数的影响：（1）含熔体的Eccomelt356.2的清洁/脱气（2）合金/改性元素的量（Sr，TiB_2）（3）凝固条件的影响（例如铸造工艺）（4）热等静压（HIP）工艺的影响，（5）对T6和T61回火的响应;（6）使用该材料对生产成本的影响。Eccomel356.2的炉料将采用不同的熔融金属处理工艺制备，金属质量将通过从这些熔体中浇注的样品的拉伸试验、夹杂物含量的PodFa和金相评估来评估。该研究项目将使工业合作伙伴更好地了解铸造条件对Eccomel356.2铸件性能的影响。通过该项目获得的数据，House ofMetals将能够指导其客户（铸造厂）优化其产品的使用，以获得铸件的最佳性能。这将使Eccomelt365.2合金除了作为回收产品的初始经济和环境优势外，还具有额外的竞争优势。三河中学的一名学生将参加该项目。

Eccomelt, a subsidiary of House of Metals produces and markets an aluminum alloy from the recycling ofaluminum rims through a patented process of cleaning and fragmentation. This product, known asEccomelt356.2, has a composition very similar to that of A356.2 ingots and is often diluted by foundries withprimary aluminum to form A356.2. To increase its market share and find new market opportunities forEccomelt356.2, House of Metals wants to develop foundry practices to enhance the utilization of the product inmolten metal charges without affecting the mechanical properties of cast products made in whole or in partfrom Eccomelt356.2. The project goals is to study the effect of the following parameters: (1) Cleaning /degassing of Eccomelt356.2 containing melts (2) the amount of alloying/modifying elements ( Sr, TiB2) (3) theeffect of the solidification conditions (e.g. the casting process) (4) the effect of hot isostatic pressing (HIP)process, and (5) The response to T6 and T61 tempers and (6) the effect of using this material on productioncosts. Charges of Eccomelt will be prepared with different molten metal treatment processes and metal qualitywill be assessed by tensile test form sample poured from those melt, PodFa for inclusion contents andmetallographic evaluation.This research project will enable the industrial partner to gain a better understanding of the effect of castingconditions on the properties of parts cast from Eccomel356.2. With the data obtained in this project, House ofMetals will be able to guide its customers (foundries) towards an optimal use of its product in order to obtainthe best possible properties of the castings. This should give the Eccomelt365.2 alloy an additional competitiveadvantage in addition to its initial economic and environmental advantage as a recycled product. One studentfrom the Cégep de Trois Rivières will participate in the project.
