2124 Aluminum

Verifiedmetal

2124 aluminum alloy is a copper-containing wrought aluminum alloy designed for high-strength aerospace applications requiring excellent fatigue resistance and damage tolerance. T851 temper (solution heat-treated, stress-relieved by controlled stretching, and artificially aged) provides peak strength with improved stress-corrosion cracking resistance compared to T4, making it suitable for critical structural components in aircraft and missiles operating at temperatures up to approximately 150°C.

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.
