6061 Aluminum Hexagonal Bar
6061 is commonly used for the following:
Construction of aircraft structures, such as wings and fuselages, more commonly in homebuilt aircraft than commercial or military aircraft. 2024 alloy is somewhat stronger, but 6061 is more easily worked and remains resistant to corrosion even when the surface is abraded, which is not the case for 2024, which is usually used with a thin Alclad coating for corrosion resistance.
Yacht construction, including small utility boats;
Automotive parts, such as wheel spacers;
Some tactical flashlights;
Aluminium cans for the packaging of food and beverages;
6061-T6 is used for:
Bicycle frames and components;
Many fly fishing reels;
The famous Pioneer plaque was made of this particular alloy;
The secondary chambers and baffle systems in firearm sound suppressors (primarily pistol suppressors for reduced weight and improved mechanical functionality), while the primary expansion chambers usually require 17-4PH or 303 stainless steel or titanium;
The upper and lower receivers of many AR-15 rifle variants;
Many aluminium docks and gangways are constructed with 6061-T6 extrusions, and welded into place;
Material used in some ultra-high vacuum (UHV) chambers;
Many parts for remote controlled model aircraft, notably helicopter rotor components;
