What's Inside This Aluminium 7075 MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for our highest-strength alloy, frequently chosen as a lightweight replacement for steel in mission-critical aerospace and defense applications.
- Full Traceability: Certified with TC No.: S74/26-XX and corresponding ASTM B211 specifications.
- Zinc & Copper Alloy: Detailed breakdowns verifying the high Zinc (5.10% - 6.10%), Magnesium (2.10% - 2.90%), and Copper (1.20% - 2.00%) content. This specific chemistry makes 7075 one of the strongest commercially available aluminum alloys.
- Extreme Strength-to-Weight Ratio: Verification of mechanical properties that rival many structural steels, but with only one-third of the weight, making it vital for aircraft structures and highly stressed military equipment.
- Mechanical Properties (T6 Temper): Comprehensive reporting of Tensile Strength (585.50 MPa), Yield Strength (525.20 MPa), Elongation (12.50%), and Hardness (152 HB), verifying ultimate precipitation hardening.
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — Aluminium 7075 MTC Certificate
Why is Aluminium 7075 stronger than other aluminum alloys?
Aluminium 7075 achieves its massive strength through the heavy addition of Zinc (5.10% - 6.10%) alongside Magnesium and Copper. When solution heat-treated and artificially aged to the T6 temper, it undergoes intense precipitation hardening. This results in a tensile strength that rivals many structural steel alloys, but at a fraction of the weight.
Does 7075 require special corrosion protection?
Yes. The high concentration of Zinc and Copper that gives 7075 its incredible strength also reduces its natural corrosion resistance compared to 5000 or 6000 series alloys. For this reason, 7075 fasteners are frequently anodized, alclad, or coated with protective finishes to prevent galvanic and environmental corrosion.
Are the materials free from radioactive contamination?
Yes, the document strictly states that the material is free from radioactive contamination and undergoes a 100% visual inspection to ensure it is free from defects.
