2519 Aluminum T87
Verifiedmetal2519 aluminum alloy is a copper-lithium-magnesium aluminum alloy designed for cryogenic and elevated-temperature aerospace applications, offering high strength-to-weight ratio with excellent fracture toughness at temperatures from -320°F to 350°F. The T87 temper (solution heat-treated, overaged, and artificially aged) provides controlled yield and ultimate strength with improved stress-corrosion cracking resistance compared to T8 tempers, making it suitable for critical aircraft fuselage and structural applications per MIL-DTL-46192 specifications.

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.
