A357.0

Verifiedmetal

A357.0 is a cast aluminum-silicon alloy (Al-7Si-0.6Mg) designed for aerospace and high-performance applications requiring good castability and elevated temperature strength. The T6 temper (solution heat-treated and artificially aged) provides enhanced mechanical properties with improved strength retention at service temperatures up to approximately 150°C.

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.
