2618 Aluminum T61
Verifiedmetal2618 aluminum is a copper-aluminum alloy with magnesium and iron additions designed for elevated-temperature aerospace applications, offering strength retention up to 300°C. The T61 temper (solution heat-treated, artificially aged, and stress-relieved) provides optimal combination of tensile strength and thermal stability in die-forged components for aircraft engines and gas turbine applications.

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.
