Deskripsi
The effect of Cu and Zr additions and annealing temperature on electrical conductivity and hardness of the Al−1.5 wt.% Mn alloy in the form of as-cast ingots and cold rolled sheets has been investigated. It is shown that due to the formation of low alloyed aluminum solid solution and Al<sub>20</sub>Cu<sub>2</sub>Mn<sub>3</sub> and Al<sub>3</sub>Zr (L1<sub>2</sub>) phase nanoparticles, the 1.5MnCuZr alloy is superior to the base 1.5Mn alloy both in the hardness (up to two times) and electrical conductivity (up to 30%) after metal processing and annealing. A new alloy can be considered as a replacement for existing 6201 type conductive alloys.
