What's the effect of manganese on aluminum bars?
The recrystallization grain is mainly through the MnAl6 compound dispersed particles on the recrystallization behavior plays another role hinder the function of.MnAl6 is to dissolve iron impurity, form (Fe, Mn) Al6, reduce the harmful effects of iron. Manganese is an important element of Aluminum Alloy, can be joined to form Al-Mn two alloy, more is to join and other elements, so most Aluminum Alloy contain manganese.
The recrystallization process of manganese stop Aluminum Alloy, improve the recrystallization temperature, and recrystallization grain refinement was developed.
Al-Mn alloy flat part in the equilibrium phase diagram of the eutectic temperature of 658, manganese in solid solution in the body for the maximum solubility strength of 1.82%. alloy increased with the increasing solubility, manganese content is 0.8%, the elongation rate reached the maximum value of.Al-Mn alloy is non hardening alloy that can be strengthened by heat treatment.
