2024 Aluminum T851
metal2024-T851 is a precipitation-hardened aluminum-copper alloy (4.4% Cu, 1.5% Mg, 0.6% Mn) that combines high strength with controlled ductility through solution treatment, controlled cold work, and stress relief; primary applications include aircraft fuselage skin, wing components, and structural fasteners requiring fatigue resistance and damage tolerance in the -65°F to +250°F service range.

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.
