2017 Aluminum T4

Verifiedmetal

· T451· T42

2017 is a copper-alloyed aluminum alloy with high strength and excellent machinability, primarily used in aerospace fasteners and structural components requiring good fatigue resistance. The T4 temper (solution heat-treated and naturally aged) provides tensile strengths around 62 ksi yield and 90+ ksi ultimate with moderate ductility, suitable for applications up to approximately 250°F.

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.
