354.0 Aluminum Casting

Verifiedmetal

354.0 is a silicon-copper-magnesium aluminum casting alloy designed for high-strength aerospace applications requiring good castability and elevated-temperature capability. The T6 temper (solution heat-treated and artificially aged) provides enhanced strength and hardness suitable for engine components, transmission housings, and structural castings operating up to approximately 300°F (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.
