Machinability:

These materials are designed to be easily machinable, allowing for precise fabrication of aircraft components and structures.

Toughness:

Aircraft-grade aluminum should also exhibit good toughness properties, which are essential for absorbing impacts and handling dynamic loads during flight.

Certification:

To meet aviation safety standards, manufacturers of aircraft-grade aluminum sheet and plate often adhere to strict quality control and certification processes. This ensures that the materials meet the necessary specifications and standards for use in aircraft construction.

Хэрэглээ:

Aircraft-grade aluminum is used in a wide range of aircraft components, including wings, fuselages, буух төхөөрөмж, structural supports, and various interior and exterior components. It is also used in the aerospace and defense industries for similar reasons.

Aircraft Grade Aluminum Sheet/Plate

Sheet vs. Таваг:

In terms of form, aircraft-grade aluminum can be found in both sheet and plate forms. Sheets are typically thinner, while plates are thicker. The choice between sheet and plate depends on the specific application and structural requirements.

Different grades of aviation aluminum sheets are applied to different aircraft components

Одоогоор, the aluminum alloy used in aircraft structure in the world is mainly high-strength 2 цуврал (2024, 2017, 2A12, гэх мэт.) and ultra-high-strength 7 Цуврал (7075, 7475, 7050, 7A04, гэх мэт.), Үүнээс гадна, there are some 5 Цуврал (5A06, 5052, 5086, гэх мэт.) болон 6 Цуврал (6061, 6082, гэх мэт.) and a small number of other series of aluminum materials.

2024 T3 Aluminum Sheet:
This is the most common of the high-strength aluminum alloys. It is of high-grade aircraft quality. The 2024-T3 aluminum sheet is thought of as the aircraft alloy because of 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, cowls, нисэх онгоцны бүтэц, and also for repair and restoration because of its shiny finish (2024-T3 Alclad).

3003 H14 Aluminum Sheet:
Most widely used of aluminum alloys, pure aluminum with manganese added for strength, approx 20% stronger than the 1000 цуврал(purre aluminium). 3003-H14 aluminum sheet has great workability and may be deep drawn, spun, гагнасан, or brazed. 3003 aluminum sheet is NON-heat treatable. This aluminum sheet is widely used for cowls and baffle plating.

5052 H32 Aluminum Sheet:
This one has the highest strength in the NON-heatable alloy series. It is not structural. 5052 aluminum sheet has higher fatigue strength than most alloys. 5052 aluminum sheet has excellent corrosion resistance, particularly in marine applications and has excellent workability. 5052 aluminum sheet is commonly used to built fuel tanks.

5083 хөнгөн цагаан хуудас:
5083 aluminum sheet belongs to Al-Mg-Si aluminium alloys. Its main contents are Magnesium and Silicon except for Aluminium. Over 4.0% of Magnesium enables 5083 aluminum sheets to have excellent resistance to correction and are easily welded. By adding copper, 55083 aluminum sheet has 28% Electrical conductivity. 5083 aluminum sheet also has good forming characteristics for either hot or cold working. But hardening is accomplished by means of cold working only. Түүнээс гадна, нь 5083 aluminum sheet does have good strength but is non-heat-treatable.

6061 T6 Хөнгөн цагаан хуудас:
This alloy has very good corrosion resistance and finishing ability, welding goes without any problems too. The strength level of the 6061-T6 aluminum sheet is about that of mild steel. The 6061-T6 aluminum sheet can be fabricated by most of the commonly used techniques. Typical uses are aircraft landing mats, truck bodies and frames, бүтцийн бүрэлдэхүүн хэсгүүд, болон бусад.

7075 Хөнгөн цагаан хуудас:
Aircraft manufacturers use high-strength alloys (principally alloy 7075) to strengthen aluminum aircraft structures. Хөнгөн цагааны хайлш 7075 has Copper (1.6 %), магни (2.5 %) and zinc (5.6 %) added for ultimate strength, but the copper content makes it very difficult to weld. Нөгөө талаар, it anodizes really beautifully. 7075 has the best machinability and it will result in a very nice finish.

What is the difference between aircraft aluminum and regular aluminum?

Aircraft aluminum, also known as aircraft-grade aluminum, and regular aluminum differ primarily in terms of their specific alloy compositions, механик шинж чанар, and manufacturing processes. These differences make aircraft-grade aluminum suitable for aerospace and aviation applications, while regular aluminum is used for a wide range of everyday applications. Here are some key distinctions:

1. Alloy Composition:
   • Aircraft Aluminum: Aircraft aluminum is made from specific high-strength aluminum alloys that are carefully engineered to meet the rigorous demands of the aviation industry. Common alloys include 2024, 6061, болон 7075, among others. These alloys often contain additional elements like copper, цайр, and magnesium to enhance strength, зэврэлтэнд тэсвэртэй, and other properties.
   • Regular Aluminum: Regular or commercial aluminum typically refers to common alloys like 1100, 3003, болон 5052. These alloys are more straightforward in composition and may not have the same level of strength or specialized properties as aircraft-grade alloys.
2. Strength and Mechanical Properties:
   • Aircraft Aluminum: Aircraft-grade aluminum alloys are chosen for their high tensile strength, ургацын хүч, and fatigue resistance. They are designed to withstand the stresses and loads experienced during flight.
   • Regular Aluminum: Regular aluminum alloys may have lower strength compared to aircraft-grade alloys, making them suitable for a wide range of non-critical applications but less ideal for high-stress situations.
