Benefits of Aviation Aluminum Plate
Lightweight: Reduces the overall weight of aircraft, improving fuel efficiency and range.
Corrosion Resistance: Provides excellent resistance to corrosion, extending the service life of aircraft components.
Strength and Durability: Offers high strength and durability, ensuring the structural integrity of aircraft.
Recyclability: Environmentally friendly as it can be recycled multiple times without losing its properties.
Manufacturing Process
Extrusion: Aluminum ingots are heated and extruded through dies to form the desired profiles.
Rolling: The extruded profiles are rolled to achieve the required thickness and flatness.
Heat Treatment: The rolled plates undergo heat treatment to achieve specific mechanical properties.
Surface Treatment: Processes like anodizing or powder coating are used to enhance corrosion resistance and aesthetics.
Packaging, Handling, & Storage
Packaging: Typically packaged in protective materials such as plastic film, brown paper, or wooden pallets to prevent damage during transportation.
Handling: Requires careful handling to avoid scratches or deformation, especially during loading and unloading.
Storage: Should be stored in a dry, well-ventilated area, away from moisture and corrosive substances to maintain its quality and properties.
