Aircraft Grade Aluminum Sheet Plate

What is Aircraft Grade Aluminum Sheet Plate

Aircraft Grade Aluminum Sheet Plate is an alloy that has undergone special treatment such as high-temperature oxidation, and can withstand thousands of degrees of high temperature or strong impact.

It is an aluminum product with high strength and anti-corrosion performance. It has the characteristics of lightness and durability. Since it was first widely used in high-tech fields such as the manufacture of Aircraft equipment, it is called Aircraft aluminum plate.

What is the meaning of Aircraft Grade Aluminum Sheet Plate

Aircraft Grade Aluminum Sheet Plate is not an exact aluminum alloy, but refers to all aluminum alloys that can meet Aircraft Grade.

Due to the relatively high requirements for weight reduction and strength in the use of aerospace materials, aluminum alloys have become the best choice.

Aluminum used in aircraft has three main benefits

• Aluminum is lightweight. Using aluminum significantly decreases the weight of an airplane. Not only does this help the plane stay in the air, but it also makes it more fuel-efficient and able to carry bigger loads.

• Aluminum is strong. The strength of aluminum makes it an ideal replacement for heavier metals.

• Aluminum is extremely resistant to corrosion, which is important in maintaining the safety of an airplane’s structure as it flies through a wide variety of environments.

Typical Uses of 2024 Aircraft Aluminum Sheet Plate

As one of the best high-strength aluminum alloys and possessing excellent fatigue resistance, aluminum 2024 is commonly used for:

• Structural components of aircraft, such as wings and fuselage
• Aircraft fittings
• Truck wheels
• Hardware
• Parts required by the transportation industry
• Scientific instruments
• Veterinary equipment

6061-T6 aluminum application in aircraft manufacturing

This alloy is known for its high corrosion resistance and finish. It is easily welded and nearly as strong as mild steel.

6061 t6 aluminum sheet is commonly used in the manufacture of landing pads for aircraft, truck bodies, frames, and structural components. It can be manufactured using the most common techniques, which is an excellent property.

Three Tempers of 6061 Aluminum Sheet

6061-O temper has maximum ultimate tensile strength no more than 150 MPa, maximum yield strength no more than 80MPa and elongation of 10–18%.

6061-T4 temper has maximum ultimate tensile strength no more than 180 MPa, maximum yield strength no more than 110 MPa and elongation of 10–16%.

6061-T6 temper has maximum ultimate tensile strength of at least 290 MPa, maximum yield strength of at least 240 MPa that is higher than certain types of stainless steel.

Application of 6061 Aluminum Sheet

Because of its corrosion resistance and light weight, it is often used for aircraft 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.

7075 aluminum alloy plate

Alloy 7075 aluminum plates are the outstanding member of the 7xxx series and remains the baseline among the highest strength alloys available. Zinc is the primary alloying element giving it strength comparable to steel. Temper T651 possesses good fatigue strength, fair machinability, resistance welding and corrosion resistance ratings.

7075 aluminum alloy is one of the strongest aluminum alloys available, making it valuable in high-stress situations. Its high yield strength (>500 MPa) and its low density make the material a fit for applications such as aircraft parts or parts subject to heavy wear. While it is less corrosion resistant than other alloys (such as 5083 aluminum alloy, which is exceptionally resistant to corrosion), its strength more than justifies the downsides.

Characteristic Of 7075 aluminum alloy

• Poor formability or workability
• Poor weldability
• Fair machinability
• Average resistance to corrosion
• Heat-treated
• High strength

7075 aluminum alloy application

Due to its high strength and good resistance to stress-corrosion cracking, aluminum 7075 is commonly used for:

• Structural parts that are highly stressed
• Fittings for aircraft
• Shafts and gears
• Components of missiles
• Additional parts for the aircraft and aerospace industry
