7020 aluminum tube is a high-strength Al-Zn-Mg alloy with excellent weldability and fatigue resistance. While slightly lower in strength than 7075 aluminum alloy, 7020 offers superior stress corrosion resistance, making it particularly well-suited for applications subject to dynamic loads. Common applications include railway components, motorcycle frames, scaffolding, and military structural components, all of which require exceptional safety and reliability.
👉 ZGGDMETAL offers a full range of 7020 aluminum tubes in stock and custom options. We have comprehensive mold resources, eliminating the need for additional mold costs and reducing procurement costs. Please review the detailed 7020 Aluminum Tube Specifications for more technical specifications and inventory information.
