Aluminum-Magnesium Alloys - an overview

Magnesium–aluminium alloys contain 8–9% Al with up to 2% of zinc to increase the strength and 0.3% Mn, which improves the corrosion resistance. From the Mg–Al phase diagram, Fig. 3.10 , it will be seen that increasing quantities of the β-phase (Mg 17 Al 12 ) will be

The Chemistry of Aluminium, Iron and Manganese

The oxides of aluminium, iron and manganese, particularly the poorly crystallized and microcrystalline forms, are undoubtedly the most reactive components of acidic soils. The elements are initially liberated into solution as cations by acidic weathering of soil minerals, and then reprecipitated, either locally or after translocation, as hydrous oxide species of high specific surface area and reactivity.

About Manganese - International Manganese Institute

2021-2-25  Manganese it´s an essential component of steel-making process because it improves certain properties that steel by itself doesn´t have. To name a few, manganese allows to avoid a phenomenon called “hot shortness”, which causes a surface cracking process at high temperatures, it has an important ability to combine with Sulphur (an unwanted element in steel), and it has a powerful deoxidation
