2024 Aluminum T4
metalUNS A92024
2024 Aluminum T4 is a copper-aluminum alloy in solution heat-treated and naturally aged condition, providing tensile strength of approximately 70 ksi (485 MPa) with good fatigue resistance and machinability, commonly used in aircraft fuselage skin, wing structures, and high-stress fasteners where moderate strength and damage tolerance are required. The T4 temper offers superior fracture toughness compared to the overaged T3 condition, though with slightly lower strength, making it the preferred specification for critical aerospace structures subject to fatigue and impact loading.

Quality & Standards
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
