7075 T6 Aluminum Alloy Rod, Mechanical Properties Machine Chemical Composition?

The main composition of 7075 alloy aluminum is: zinc is the main alloying element in the system, adding magnesium to the alloy containing 3 zinc can form MGZN2 with significant strengthening effect, so that the heat treatment effect of the alloy is far better than that of aluminum-zinc binary alloy. Increasing the zinc and magnesium content in the alloy will further improve the tensile strength, but its ability to resist stress corrosion and spalling corrosion will decrease.

After heat treatment, very high strength characteristics can be achieved. The materials of this system generally add a small amount of copper, chromium and other alloys, among which 7075 T651 aluminum alloy is particularly high-grade, known as the best product in aluminum alloy, with high strength, far better than mild steel. This alloy also has good mechanical properties and anodic reaction.

Representative uses include aerospace, mold processing, machinery and equipment, tooling and fixtures, especially used in the manufacture of aircraft structures and other high-stress structures that require high strength and strong corrosion resistance. Product use features:

1. Microstructure compactness: the unique grain refinement process ensures that all aviation products have passed the ultrasonic flaw detection process inspection of aerospace aluminum alloy products, and there are no sand holes, cracks, bubbles and impurities.

2. Internal stress (artificial aging): perfect pre-stretching to eliminate internal stress process, completely eliminate internal stress, and the product will not warp, crack and deform during processing and stress.

3. Tolerance accuracy: All products comply with the American Society for Testing and Materials (ASTM) and Aerospace Materials (AMS), and the tolerance index of most products can exceed the tolerance accuracy of ASTM1 2, and the tolerance index of some products can even exceed the standard tolerance accuracy of ASTM1 4.

4. Processing performance: the deviation of chemical composition, strength and hardness is minimized, and there will be no "sticky knife" and "chipping" phenomenon in processing.

5. Uniformity: The heat treatment technology is excellent, and the product is below 300mm thickness (or diameter), and the strength and hardness can be consistent.

6. Stability: The production process is all computer-controlled, with no human deviation, and the performance of different batches can also be guaranteed.

7. Anodizing effect: The anodizing effect is uniform and shiny, and there is no "stripe" or "spot" on the surface, and the color is different.

8. Corrosion resistance: Through the microscopic inspection of metals and alloys, it has excellent stress corrosion resistance and corrosion resistance to peeling, and will not produce pits or blackening in various media (such as water vapor, weak acid and weak alkali, etc.) for a long time.

9. High temperature resistance: no permanent deformation will occur when working at 400°C.

10. Bending performance: all plates have passed the semi-conductive bending test, and there will be no cracking when bending 180 degrees.

I'm afraid this will have to be solved by professionals.
