Product Overview
Ti-5Al-2.5Sn wire is a near-alpha titanium alloy wire developed for good elevated-temperature capability and stable mechanical performance. It is commonly used in aerospace and high-performance industrial applications where improved strength and creep resistance are needed compared with commercially pure titanium, while maintaining good corrosion resistance and weldability under controlled conditions.

National Grade Designations
- International designation: Ti-5Al-2.5Sn
- USA: UNS R54520 (commonly referenced), supplied per ASTM/AMS requirement
- China: equivalency to be confirmed per GB/enterprise specification before substitution
- Russia: PT-3V is not equivalent; confirm exact requirement before use
Certifications and Standards
- ISO 9001 quality management system available
- EN 10204 3.1 inspection certificate available
- Chemical analysis and heat/lot traceability available per order
- ASTM/AMS compliance available when specified at purchase
Notes and Precautions
- Mechanical properties depend on diameter, processing route, and heat treatment condition; specify your required condition (annealed/cold-worked/stress relieved).
- For welding or critical joining, strict cleanliness and inert gas shielding are required per your WPS to prevent oxygen pickup.
- Do not substitute “similar” alloys without confirming chemistry and allowable data under the governing standard.
