2219 Aluminum T87
metal2219 aluminum alloy T87 is a copper-alloyed aluminum (4.8-6.3% Cu, 0.3% Mn, 0.02% Zr) in artificially aged condition (T87) providing high strength at cryogenic and elevated temperatures (to ~300°C) with good fracture toughness and fatigue resistance. Primary applications include aerospace cryogenic tankage, rocket motor cases, and structural components in space launch vehicles where strength-to-weight ratio and thermal cycling durability are critical.

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.
