The Effect of Two-Step Aging on the Electrical Properties of 7075 Aluminum Alloy
This experiment has taken a research on the conductivity changes of 7075 aluminum alloy after being extruded and two-step aging treatment,and has done a analysis on the theory and rules of the impact on conductivity performance under the two-step aging treatment.Compared to cast aluminum alloy and extruded aluminum alloy without two-step aging process,the experiment showed that extruded alloy with two-step aging treatment has the highest conductivity about 44% IACS, 33.3% more than under casting condition and 22.2% more than only being extruded.
