7075 Al-Zn-Mg-Cu Strengthened Aluminum Alloy Rod

7075 is an ultra-high-strength, heat-treatable aluminum alloy belonging to the Al-Zn-Mg-Cu system (a 7000-series "aerospace-grade" aluminum). It derives its strength from the precipitation of the MgZn₂ phase and ranks among the strongest commercially available aluminum alloys. Common tempers include T6 and T651 (the latter involves pre-stretching for stress relief, making it the preferred choice for precision machining).

7075 is an ultra-high-strength, heat-treatable aluminum alloy belonging to the Al-Zn-Mg-Cu system (a 7000-series "aerospace-grade" aluminum). Its strength is derived from the precipitation of the MgZn₂ phase, making it one of the strongest commercially available aluminum alloys. It offers excellent machinability but has poor weldability; it is also susceptible to stress corrosion cracking and exhibits lower corrosion resistance compared to 6000-series alloys. Common tempers include T6 and T651 (the latter involves pre-stretching for stress relief and is the preferred choice for precision machining).

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
