Manufacturing Process Of 7075 Aluminum Round Tube
7075 aluminum round tubes supplied by GNEE are typically manufactured using the following processes:
Extrusion or Cold Drawing: Produces seamless tubes with uniform wall thickness and consistent mechanical properties.
Heat Treatment (T6, T651, etc.): Involves solution heat treatment, rapid quenching, and artificial aging to achieve peak strength.
Seamless tube structures are especially valuable as they eliminate weld seams and joints, ensuring superior uniformity and reliability in high-stress applications.
Manufacturing Considerations
Welding: Welding is challenging due to the alloy's susceptibility to cracking. Specialized techniques, such as TIG welding with 5356 filler material, are required. In most cases, mechanical fastening is recommended over welding.
Machining: 7075 aluminum round tube machines well when sharp cutting tools are used, producing smooth surface finishes.
Surface Finishing: Common treatments include anodizing, painting, or powder coating to improve corrosion resistance and enhance appearance.
Usage Considerations
Processing Conditions: Coolants should be applied during machining to reduce cutting temperatures and minimize work hardening, which can accelerate tool wear.
Environmental Exposure: For long-term use in highly corrosive environments, such as marine or coastal conditions, additional surface protection is strongly recommended.
Weldability: Due to limited weldability, riveted or bolted joints are often preferred alternatives to welded connections.
