Aluminium–magnesium alloys (AlMg) – standardised in the 5000 series – are aluminium alloys that are mainly made of aluminium and contain magnesium as the main alloy element. Most standardised alloys also contain small additives of manganese ( AlMg(Mn) ).
Appropriately alloyed and treated, aluminum can resist corrosion by water, salt, and other environmental factors, and by a wide range of other chemical and physical agents. The corrosion characteristics of aluminum alloys are examined in the section “Effects of Alloying on Corrosion Behavior” in this article.
20 kwi 2022 · We reveal that this alloy has a record low degradation rate amongst all magnesium alloys in practically relevant corrosive solutions, and it even withstands seawater corrosion.
Magnesium alloys are used for both cast and forged components, with the aluminium-containing alloys usually used for casting and the zirconium-containing ones for forgings; the zirconium-based alloys can be used at higher temperatures and are popular in aerospace.
4 cze 2024 · High-purity Mg exhibits better corrosion resistance but is difficult to produce. When Mg coupled to common alloy elements, galvanic corrosion occurs and results in a significantly elevated corrosion rate.
1 cze 2024 · In this study, we investigate the microstructure, mechanical properties, and corrosion properties of Al-xMg-Mn alloys in both hot-rolled and cold-rolled states. The Al-Mg-Mn alloys with varying Mg contents were prepared through gravity casting followed by hot-rolling and cold-rolling deformation.
Magnesium, the lightest structural metal, has inherently poor corrosion resistance. In this study, we developed a magnesium-aluminium Mg-10.6Al-0.6Zn-0.3Mn alloy, additively...
