Eccomelt, a subsidiary of House of Metals, produces and markets an aluminum alloy from the recycling of aluminum rims through a patented process of cleaning and fragmentation. This product, known as Eccomelt356.2, has a composition very similar to that of A356.2 ingots and is offered to foundries as a substitute for primary aluminum A356.2. To increase its market share in the critical automotive market, House of Metals wants to develop foundry practices including dilution with A356.2 virgin ingots without affecting the mechanical properties of cast products made in whole or in part from Eccomelt356.2. The project goal is to study the effect of the molten metal treatment on metallurgical quality of casting in the T6 and T61 tempers of sand, permanent mold and high pressure die casting usually with special adapted heat treatments. Charges of Eccomelt will also be prepared with different mixing ratio of virgin ingots to Eccomelt356.2 treated with the best molten metal treatment processes. Metal quality will be assessed by tensile test from sample poured from those melt, by PoDFA for inclusion contents and metallographic evaluation.This research project will enable the industrial partner to gain a better understanding of the effect of casting conditions on the properties of parts cast from Eccomelt356.2. With the data obtained in this project, House of Metals will be able to guide its customers (foundries) towards an optimal use of its product in order to obtain the best possible properties of the castings. This should give the Eccomelt365.2 alloy an additional competitive advantage in addition to its initial economic and environmental advantage as a recycled product. One student from the Cégep de Trois Rivières will participate in the project for each year of the project.

Eccomelt是House of Metals的子公司，通过专利的清洁和破碎过程，生产和销售铝轮辋回收的铝合金。该产品被称为Eccomelt356.2，其成分与A356.2锭非常相似，可作为原铝A356.2的替代品提供给铸造厂。为了增加其在关键汽车市场的市场份额，House of Metals希望开发铸造实践，包括在不影响全部或部分由Eccomelt356.2制造的铸造产品的机械性能的情况下，使用A356.2原始锭进行稀释。本课题的目的是研究通常采用特殊热处理的砂型、永久型和高压压铸件的T6和T61回火中熔融金属处理对铸件冶金质量的影响。用最佳的熔融金属处理工艺处理过的Eccomelt356.2，用不同的混合比例制备Eccomelt料。金属质量将通过从这些熔体中浇注样品的拉伸试验来评估，通过PoDFA来评估夹杂物含量和金相评价。该研究项目将使工业合作伙伴能够更好地了解铸造条件对Eccomelt356.2铸件性能的影响。根据该项目获得的数据，House of Metals将能够指导其客户（铸造厂）对其产品进行最佳使用，以获得铸件的最佳性能。这应该给Eccomelt365.2合金一个额外的竞争优势，除了其最初的经济和环境优势作为回收产品。在项目的每一年，将有一名来自巴黎三河学院的学生参加该项目。
