Aircraft Aluminum Plate

Aircraft aluminum plate is lightweight, strong and corrosion resistant, although it loses some strength at high temperatures, it gains strength at sub-zero temperatures, which is very useful in aerospace, where aircraft are often exposed to extremely low temperatures flight. Today, the use of aluminum in aviation has become more and more complex. Almost all parts such as fuselage, wings, doors, floors and seats are made of aluminum plate. There are few parts that can be replaced by aluminum. The fuselage of Boeing 737 is 80% made of aluminum.

1, 2024-T3

2024-T3 consists of 4.5% copper, 0.6% manganese and 1.5% magnesium. This is a top-of-the-line high-strength aluminum alloy and is fatigue-resistant, making it one of the most common aircraft aluminum plate alloys. While it is not suitable for welding and is not heat treatable, it is a good choice for repair work due to its excellent finish.

2, 6061-T6

6061-T6 consists of 0.25% copper, 0.6% silicon, 1.0% magnesium and 0.25% chromium. This alloy also has a good finish. In addition to this, it has good corrosion resistance and is ideal for welding. Its strength and machinability are comparable to mild steel. It is heat treatable.

3, 3003-H14

3003-H14 contains 1.2% manganese and is the most widely used aluminum alloy. It is easy to work, and while it cannot be heat treated, it can be cold worked to increase its strength.

4, 7075-T6

7075-T6 consists of 1.6% copper, 2.5% magnesium and 5.6% zinc. Aircraft manufacturers often use 7075 aluminum plate to enhance the structure of their aircraft. Due to its 1.6% copper content, it has poor solderability but strong machinability. It is heat treatable.

5, 5052-H32

5052-H32 consists of 2.5% magnesium and 0.25% chromium. This alloy has the highest strength of the non-heated alloy family and can be increased by cold working. It also has excellent fatigue strength, corrosion resistance and machinability, making it an excellent material for aircraft aluminum plate and marine applications.
