What Are The Uses of Aluminum Alloys 2024 and 7075

Aluminum alloy 2024 t3 is considered an aircraft alloy due to its strength, and it also has excellent fatigue resistance. Welding is generally not recommended. Typical uses for 2024-T3 Alclad aluminum sheet are fuselage and wing skins, roofs, aircraft structures, and repair and restoration due to its lustrous and smooth finish (2024-T3 Alclad). Its ultimate strength is 62,000 PSI and its shear strength is 40,000 PSI.

2024 aluminum alloy is widely used in various special applications due to its excellent performance. Here are some common special uses of 2024 aluminum alloy:

1. Aerospace: Due to its excellent strength and lightweight characteristics, 2024 aluminum alloy is often used to manufacture aircraft structural parts, aircraft shells, and aircraft engine parts. Its good processing performance and corrosion resistance also make it an ideal choice for the aerospace field.

2. Automobile manufacturing: In the automotive manufacturing industry, 2024 aluminum alloy is often used to manufacture components such as body structures, engine parts, wheels, and suspension systems. Its high strength and excellent fatigue resistance can improve the safety and durability of the car.

3. Sports equipment: Due to its good strength and durability, 2024 aluminum alloy is often used to manufacture various sports equipment, such as bicycle frames, golf clubs, and ski parts. Its lightweight characteristics also help to improve the performance of sports equipment.

7075 aluminum alloy is a high-strength, heat-treatable deformable alloy developed by Alcoa in 1943. The alloy contains zinc, magnesium, chromium and copper as hardeners, as well as small amounts of iron, silicon, manganese and titanium. After heat treatment, Al-7075 is much stronger than carbon steel. Its common tempers are 7075 t351, T651, T73, T76, T7651,etc.

The excellent strength characteristics of 7075 aluminum make it an ideal choice for manufacturing aircraft main structures. Its tensile strength is as high as 500MPa and its yield strength is far higher than that of general industrial pure aluminum. It can effectively resist aerodynamic loads and other complex stresses while ensuring structural stability.
