2124 Aluminum T851
Verifiedmetal2124 aluminum alloy is a Cu-containing aerospace aluminum with high strength-to-weight ratio, used primarily in aircraft fuselage and structural applications requiring elevated temperature performance. T851 temper (solution heat-treated, stress-relieved, and overaged) provides controlled strength with improved stress-corrosion cracking resistance suitable for critical loaded components.

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.
