Abstract

This paper focuses on integrated methodology for the experimental mechanical properties of produced AA6061 aluminum alloy, coupled for a rigorous quality assurance framework to validate material reliability for structural applications. The approach combines microstructural analysis, tensile testing analysis, and systematic measurement uncertainty quantification, all performed through the relevant international standards. To ensure statistical reliability, the overall standard uncertainty was computed utilizing the propagation law of uncertainty for k = 2 with a confidence level of roughly 95%. The experimental results yielded a tensile strength of309.4±4.0N/mm2, showing excellent repeatability with a lower relative uncertainty that correspond to 1.3%. These values not only meet the mechanical property requirements stipulated in international standards for AA6061 alloy but also confirm the experimental protocol reliability. The findings validate the material's suitability for demanding engineering environments and highlight the importance of embedding uncertainty quantification within standard characterization practices to support informed design decisions
