　　Aircraft Aluminum Extrusions are high-performance aluminum alloy extrusions designed and manufactured for the aerospace industry. This type of material is an ideal choice for aircraft structural parts due to its excellent strength-to-weight ratio, corrosion resistance and processing performance. Aircraft aluminum extrusions are widely used in fuselage frames, wing ribs, skins and other key components to ensure the safety, reliability and efficiency of aircraft.

　　Main features of aviation aluminum extrusions

　　High strength and light weight:

　　Aviation aluminum extrusions have an extremely high strength-to-weight ratio, which can provide sufficient structural support while reducing the weight of the aircraft, helping to improve fuel efficiency and extend the range.

　　Excellent corrosion resistance:

　　Aluminum alloys naturally have good corrosion resistance, and their durability in harsh environments can be further enhanced through appropriate surface treatment (such as anodizing, chemical plating, etc.).

　　Excellent mechanical properties:

　　Excellent tensile strength, fatigue strength and fracture toughness enable aviation aluminum extrusions to withstand stress and loads under extreme conditions.

　　Good processing performance:

　　Easy to cut, bend, drill and weld, suitable for complex shapes and sizes, and meet the strict design requirements of the aerospace industry.

　　Heat treatment strengthening:

　　Certain aluminum alloys can be significantly improved through heat treatment processes to adapt their mechanical properties to more demanding application requirements.

　　High electrical and thermal conductivity:

　　This is an important property for parts that need good electrical or heat dissipation performance, such as electrical systems and engine components.

　　Easy maintenance and repair:

　　Aluminum is easier to repair in the field than other metal materials, reducing downtime and costs.

　　Environmental sustainability:

　　Aluminum is a recyclable material, which helps reduce resource waste and environmental impact.

　　Common aviation aluminum alloy types

　　2024-T3: Widely used in aircraft skin and wing structures because it provides a good combination of properties, including high tensile strength and fatigue strength.

　　7075-T6: Known for its extremely high strength, it is suitable for critical structural parts that bear heavy loads, such as landing gear and load-bearing beams.

　　6061-T6: Although not as strong as the above two alloys, its weldability and processing properties make it an ideal choice for some non-load-bearing structures.

　　2014-T6: With excellent mechanical properties and corrosion resistance, it is often used to manufacture fasteners and other connectors.

　　7050-T7451: An improved version of the 7 series aluminum alloy, which has improved exfoliation corrosion resistance and fracture toughness, and is suitable for complex load-bearing components.

　　Application areas

　　Fuselage structure: such as frames, bulkheads, floor beams, etc.

　　Wing structure: ribs, spars, skins, etc.

　　Tail and control surfaces: vertical tail, horizontal tail, flaps, ailerons, etc.

　　Landing gear: struts, axles, etc.

　　Interior decoration: ceiling panels, sidewall panels, etc.

　　Engine compartment: air intake, exhaust pipe, etc.
