Industrial aluminum profiles are materials primarily composed of aluminum, with the addition of other alloy elements such as copper, magnesium, and silicon. They are produced through a series of processes including heating, extrusion, and surface treatment, resulting in materials with different cross-sectional shapes. Depending on the alloy elements added, the properties and applications of the resulting industrial aluminum profiles vary.
Aluminum is a highly reactive metal that easily combines with oxygen in the air to form a dense natural oxide film. The molar volume of this oxide film is much larger than that of aluminum, and even if it is damaged, it will immediately regenerate. Therefore, various surface processing treatments can be applied to industrial aluminum profiles, mainly including anodizing, polishing, spraying, electroplating, etc. These treatments can improve the compactness, thickness, insulation, corrosion resistance, wear resistance, heat resistance, and various decorative properties of the oxide film, making it suitable for use in various industrial environments.
Based on the different alloy elements added, industrial aluminum profiles can be divided into seven major series, ranging from Series 1 to Series 7. Each series of aluminum alloy has numerous models, each with distinct characteristics and applications. From the perspective of application fields, industrial aluminum profiles refer to all aluminum profiles except for architectural aluminum profiles, primarily including Series 2 (aluminum-copper alloy) and Series 6 (aluminum-magnesium alloy) 6063-T5 industrial aluminum profiles.
The industrial aluminum profiles of the 6063-T5 series undergo solution treatment followed by incomplete artificial aging treatment. This means that after solution heat treatment, heating or cooling treatments are applied to eliminate residual stress caused by mechanical processing, preventing deformation or cracking of the industrial aluminum profiles and enhancing their mechanical stability. Industrial aluminum profiles used in production have stringent requirements for material quality and dimensional tolerances, and are primarily applied in the automotive manufacturing industry, aerospace industry, rail transportation industry, and automated conveyor equipment.
Industrial aluminum profiles used in the aerospace industry are primarily of the 2-series, with a small amount of 7-series. Different series models are used in various applications. The main parts of aircrafts that can be used include: screws, aircraft forgings, the first-stage fuel tank of rockets, rivets, parts, propellers and accessories, aircraft structural components, pistons and cylinder heads of aircraft engines, impellers, oxidizer tanks of rockets, aircraft skins and structural components, piston and engine parts, aircraft structural components in working environments at 150-250°C, aircraft skins, frames, spars, engine compressor wheels, inducers, impellers, blades, engine pistons, as well as complex-shaped medium-strength components, stringers, landing gear, medium-thick plates of aircrafts, and structural components with high yield strength.
In the automotive manufacturing industry, industrial aluminum profiles can be used for car body panels, wheels and structural components, sunroofs, body sheet metal parts, automotive air tubes, oil tubes, decorative parts, wheels, and more.
