7005 Aluminum Rod Bar
7005 aluminum rod bar is a heat-treatable Al-Zn-Mg alloy that combines high strength, good weldability, and lightweight properties. It is widely used in welded structures requiring high strength and fracture toughness, such as trusses, struts, and containers in transport vehicles, as well as large heat exchangers and sporting equipment like tennis rackets and baseball bats.
The grade of 7075 alloy is AA 7005 / UNS A97005, listed as GB 7005 in Chinese standards and JIS 7N11 in Japanese standards. Common tempers include T1, T3, T4, T5, 7005-T6, and T8, with T6 often used for structural applications. This alloy is typically supplied in a rolled finish condition, and anodizing and coating treatments are available for enhanced surface protection or improved appearance.
HSTF 7005 Aluminum Bar Advantages
Exceptional Strength-to-Weight Ratio
As a heat-treatable 7xxx-series alloy, 7005 delivers high mechanical strength—typical T6 temper offers ultimate tensile strength (UTS) of 524–560 MPa and yield strength (YS) of 455–480 MPa—while maintaining aluminum’s low density (~2.78 g/cm³). This makes it ideal for weight-sensitive applications (e.g., bicycle frames, truck components) where structural integrity without excess mass is critical.
Superior Weldability
Unlike many high-strength 7xxx alloys. 7005 has a copper content near or below 0.2%, enabling reliable resistance welding (a common method for structural assemblies). While fusion welding requires careful process control, its weldability outperforms higher-copper 7xxx counterparts, making it a preferred choice for joined load-bearing parts.
Excellent Machinability and Surface Finish Compatibility
7005 machines cleanly with good tool life and minimal burring, supporting efficient production of precision components. It also responds exceptionally well to anodizing and polishing, allowing for durable, corrosion-resistant surfaces that meet aesthetic or functional requirements (e.g., sports equipment, automotive trim).
Balanced Corrosion Resistance and Toughness
It offers solid general corrosion resistance and, in certain tempers (e.g., T73/T76), improved resistance to stress-corrosion cracking (SCC) and exfoliation. Combined with decent elongation (~10–11% in 7005-T6), this balance of toughness and corrosion performance ensures reliability in demanding environments (e.g., outdoor machinery, marine components).
Our 7005 aluminum rod conform to international standards such as ASTM B221, EN 755, EN 573, and ISO 9001. We also provide Material Testing Certificates (MTC). These documents record chemical composition and mechanical properties. They also include dimensional tolerances. Third-party inspection reports are available upon request. This ensures quality assurance for your critical applications.
