Which of the 6061 aluminum bars, heat treated and 7075 aluminum rods, has been treated with heat?
The hardness of aluminum alloys is directly related to the chemical composition of the alloy.
However, if the hardness of the aluminum is required, it is better to use the 7075 aluminum bar. 7075 tensile strength, yield strength and hardness are better than 6061.
Secondly, the different states also have great influence. From the highest hardness, 7 lines, 2 lines, 4 lines, 6 lines, 5 lines, 3 lines, 1 lines are reduced in turn. The range of 6061 is much larger than that of 7075.
