7475-T761 Aluminum, Aramid Fiber Reinforced

Verifiedmetal

7475-T761 is a high-strength aluminum-zinc-magnesium-copper alloy reinforced with aramid fibers in sheet laminate form, delivering enhanced damage tolerance and fatigue resistance for aerospace structural applications. The T761 temper (overaged condition) provides controlled strength levels with improved fracture toughness relative to peak-hardness tempers, making it suitable for damage-critical aircraft components operating at intermediate temperatures.

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.
