C355.0 Aluminum

Verifiedmetal

C355.0 is a copper-containing aluminum casting alloy (Al-Si-Cu-Mg system) used primarily in aerospace and automotive applications requiring moderate strength and good castability. The T6 temper (solution heat-treated and artificially aged) provides enhanced mechanical properties suitable for structural components operating at elevated temperatures with improved dimensional stability and corrosion resistance compared to as-cast conditions.

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.
