355.0 Aluminum

Verifiedmetal

355.0 is a copper-silicon aluminum casting alloy designed for high-strength aerospace and automotive applications requiring good castability and elevated-temperature service. T6 temper (solution heat-treated and artificially aged) provides optimal strength and hardness for structural castings operating 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.
