แผ่นอลูมิเนียมการบิน, เป็นแผ่นอลูมิเนียมที่ออกแบบและใช้งานด้านการบินโดยเฉพาะ, ได้กลายเป็นวัสดุที่ขาดไม่ได้และสำคัญสำหรับการผลิตการบินสมัยใหม่เนื่องจากมีความแข็งแรงสูง, light weight and good corrosion resistance.

ทั้งคู่ 7075 และ 7475 aviation aluminum plates belong to the 7 ซีรีส์อลูมิเนียมอัลลอยด์. They are super-hard aluminum alloys in the aviation aluminum series and have good wear resistance, corrosion resistance and mechanical properties.

ทั้งคู่ 7075 และ 7475 aviation aluminum plates contain zinc (สังกะสี) and magnesium (มก.) 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, แต่ 7475 aluminum alloy has better fracture toughness while maintaining high strength. สิ่งนี้ทำให้ 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 อลูมิเนียม, forming a denser oxide film, thereby improving its corrosion resistance.
