Both 6061 aluminum and 7075 aluminum are heat treatable. It is interesting to note that even though 7075 aluminum is much stronger than 6061 aluminum, it melts at a slightly lower temperature. Because 6061 aluminum has a higher thermal conductivity than 7075 aluminum, it can be a better choice for certain applications.Apr 5, 2021
Why is 7075 aluminum strong?
Part of the 7000 series of aluminum, 7075 contains zinc as its major alloying element. When coupled with a small percentage of magnesium, the result is a heat-treatable alloy with very high strength. Like other grades in the 7000 series of aluminum, 7075 aluminum uses small quantities of copper and chromium as well.Sep 30, 2020
What does 7075 mean in aluminum?
ALUMINUM ALLOY 7075 GENERAL DESCRIPTION: Aluminum 7075 is a heat-treatable aluminum alloy with zinc as the primary alloying element. It has moderated formability when in the fully soft, annealed temper and can be heat-treated to strength levels that are comparable to many steel alloys.
