Alloys of 7xxx (such as A17075-T6) and 2xxx series (such as Al 2024) are often found with exfoliation corrosion. 7) Flow Induced Corrosion The resistance of aluminum alloys to flow induced corrosion depends on the stability of the protective oxide films on the surface. Dissolution of these...
Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their
Light-weight, high-strength, aluminum (Al) alloys have widespread industrial applications. However, most commercially available high-strength Al alloys, like AA 7075, are not suitable for additive manufacturing due to their high susceptibility to solidif
In addition, the low density of aluminium results in a lightweight profile compared to other materials, which is easy to handle down the supply chain, as well as being cheaper and more environmentally friendly to transport.How to change the design into a real product? CAD drawings evalua...

The 6061Al-20% (graphite, Al4C3) composite that was solution-treated for 24 h, and then peak aged, could attain a hardness level of 7075-T6 alloy. As for the wear rate, this initially increased due to the presence of the graphite particles; but with higher graphite content and ...
