A201.0 T7

Verifiedmetal

A201.0 is an aluminum-copper casting alloy with controlled impurities used primarily in aerospace engine components and high-temperature structural applications, offering superior strength retention to approximately 300°C. The T7 condition (solution heat-treated and artificially aged) provides peak hardness and yield strength with controlled ductility, balancing high-temperature capability with casting integrity for critical bearing and structural loads.

Export Control

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.
