6061 aluminum sheet is an economical, lightweight and medium-strength alloy. Its main alloy elements are Si, Mg, Mn,Ti, Zn,Cu, Fe,etc. Compared with other alloys, it has higher corrosion resistance. It also has good mechanical properties and is easily welded.
In aerospace industry, 6061 aluminum alloy is used for wing, fuselage structures and other non-critical aircraft parts, such as seat rails, handles and aircraft landing pads. It is especially common in homebuilt aircraft.
Because of its corrosion resistance and light weight, it is often used for aviation interior parts and aircraft container.
It is also an economical choice for the ultralight aircraft emphasizing safety, economy and comfort. Ultralight aircraft usually refers to a small general-purpose aircraft driven by a propeller, with a crew of no more than 2 people, and a maximum take-off weight of no more than 480kg. Most of them are made of aluminum alloy, nylon cloth, balsa wood, hard foam and other materials, and then can fly with a small engine of dozens of horsepower.

2. Haomei Aluminum has introduced a 6000T stretching machine, which is the world's most advanced equipment, to eliminate the residual internal stress of the product after quenching, and to ensure that the product is not deformed during processing and can meet customers' requirements on strength, precision tolerances, fatigue strength and corrosion resistance.
6061 VS 7075Aircraft Aluminum
Item | 6061 | 7075 |
Main Alloy | Mg: 0.80-1.2 | Zn: 5.1-6.1 |
Mechanical Properties | Tensile strength: 310 Mpa Yield strength: 275 Mpa HB: 95 | Tensile strength: 570 Mpa Yield strength: 505 Mpa HB: 150 |
Processing Ability | Machinability: Good Weldability: Weldable Surface treatment: Surface treatment such as oxidation coloring can be carried out more conveniently. Corrosion resistance: Excellent | Machinability: Good Weldability: Poor Surface treatment: The oxidation effect of 7075 is unstable. Corrosion resistance: Poor |
Aluminum Sheet Price | Under normal situations, 7075 aluminum sheet price is about 20-40% more expensive than 6061 aluminum sheet. | |
