This dataset is derived from the research project titled *Airworthiness Compliance Verification and Reliability Research on Additively Manufactured High-Strength Aluminum Alloy Components for Large Passenger Aircraft and Civil Aerospace*. According to the requirements of airworthiness compliance verification, a specimen-level material mechanical property test matrix was developed, and performance tests including static, fatigue and fracture toughness tests were conducted to obtain fundamental performance data of additively manufactured high-strength aluminum alloy materials. Combining multi-scale modeling methods, a general approach for determining the allowable design values of additively manufactured structural components was established. The data collection spanned from September 2020 to April 2021, and was carried out by Shanghai Aerospace Materials and Structure Testing Co., Ltd. All collection equipment, test environments, collection personnel and operating procedures strictly adhered to relevant quality management regulations.
