Ti-15V-3Cr-3Sn-3Al STA
metalTi-15V-3Cr-3Sn-3Al STA is a metastable beta titanium alloy in solution-treated and aged condition, combining high strength (typically 1200-1400 MPa tensile strength) with excellent fracture toughness and damage tolerance for aerospace fasteners and structural components. The STA condition provides optimized strength-toughness balance through controlled precipitation hardening while maintaining good fatigue resistance and low-temperature impact properties required in critical airframe applications.

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.
