航空用アルミニウム板, as aluminum plates designed and used specifically for the aviation field, have become an indispensable and important material for modern aviation manufacturing due to their high strength, light weight and good corrosion resistance.

Both 7075 そして 7475 aviation aluminum plates belong to the 7 シリーズアルミニウム合金. They are super-hard aluminum alloys in the aviation aluminum series and have good wear resistance, corrosion resistance and mechanical properties.

Both 7075 そして 7475 aviation aluminum plates contain zinc (亜鉛) and magnesium (マグネシウム) as the main alloy elements. The MgZn2 structure formed by these elements has a significant strengthening effect, making both alloys characterized by high strength and high hardness.

7075 aluminum alloy may be slightly inferior to 7475 aluminum alloy in strength, だが 7475 aluminum alloy has better fracture toughness while maintaining high strength. This makes 7475 aluminum alloy more advantageous in certain application scenarios where both strength and toughness need to be considered.

The corrosion resistance of 7075 aluminum alloy is relatively poor, while the 7475 aluminum alloy has better corrosion resistance. This may be due to the addition of more alloying elements to the 7475 アルミニウム合金, forming a denser oxide film, thereby improving its corrosion resistance.

7075 aviation aluminum plate:

Strength: tensile strength σb (MPaで) ≥ 560, yield strength σp0.2 (MPaで) ≥ 495.
Plasticity: The plasticity is good after solution treatment, and the strengthening effect of heat treatment is good.
Low temperature strength: good strength below 150℃.
Welding performance: Poor welding performance and tendency to stress corrosion cracking.

7475 aviation aluminum plate:

強度と靭性: High strength and good fracture toughness.
耐食性: Has better corrosion resistance.
Other properties: Specific mechanical properties such as tensile strength, 降伏強さ, 等. may vary depending on the specific state and processing method.

7075 aviation aluminum plate: mainly used to manufacture aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft upper and lower wing wall panels, ストリンガー, 等. 加えて, it is also widely used in mold processing, 機械設備, tooling fixtures and other fields.

7475 aviation aluminum plate: mainly used for aluminum-clad and non-aluminum-clad plates for fuselage, wing frames, ストリンガー, 等. and other parts that require both high strength and high fracture toughness.

Aircraft aluminum sheets are specially treated to provide extremely high strength and rigidity while maintaining a low density. This property makes it ideal for manufacturing lightweight, high-strength aerospace components, helping to improve the overall performance and fuel efficiency of aircraft.
