Features of Perforated 7075 T6 Anodized Black Aluminum Sheet
1. Superior Mechanical Strength
7075 T6 aluminum delivers tensile strength up to 572 MPa and yield strength approximately 503 MPa, making it one of the strongest aluminum alloys available. This allows the perforated sheets to maintain structural rigidity even with a large amount of open area.
2. Lightweight
At a density of approximately 2.81 g/cm³, 7075 alloy provides essential lightweight characteristics crucial in aerospace, automotive, and precision engineering applications.
3. Enhanced Corrosion Resistance via Anodizing
The black anodized layer not only offers an aesthetic, matte-black protective finish but significantly improves resistance to wear, oxidation, ultraviolet degradation, and corrosion. This ensures longevity and low maintenance in harsh environments.
4. Customizable Perforation Configurations
Perforation patterns and hole geometries can be adjusted according to specific airflow, filtration, or structural requirements. Enhanced ventilation, noise reduction, and weight savings are common benefits.
5. Excellent Machinability and Formability
Despite its hardness, the alloy is workable through standard manufacturing processes such as shearing, bending, stamping, and machining to form complex components without compromising sheet integrity.
