Ti-13V-11Cr-3Al (UNS R58010) is the first metastable beta titanium alloy to achieve practical industrial application. Its exceptional strength-to-weight ratio is attained through solution and aging heat treatments, making it a preferred material for aerospace structural components, missile systems, and high-performance springs .

ZYTC Alloy, a professional Chinese titanium alloy supplier, provides certified Ti-13V-11Cr-3Al bar, forgings, and custom stock with full material traceability.

Implementation Standards

In actual production and procurement, you should pay attention to the following standards to control material and product quality:

For bars, forgings, and forging billets, refer to SAE AMS6925D.
For plates, strip, and thick plates, refer to SAE AMS4917K.

The primary value proposition of Ti-13V-11Cr-3Al titanium alloy lies in its high structural efficiency, high reliability, and low manufacturing cost. ZYTC Alloy supplies Ti-13V-11Cr-3Al titanium alloy in the form of bar stock, primarily for custom orders. This material is not readily available in the Chinese titanium alloy market.

The alloy's beta structure enables yield strengths exceeding 180,000 psi after aging, while maintaining good formability in the solution-treated condition . Cold working prior to aging promotes uniform precipitation and improves the strength-ductility balance .

Fabrication & Heat Treatment

Process	Guidelines
Machining	Difficult; use slow speeds, high coolant flow, high feed rates. Carbide tooling (C1-C4) or cobalt high-speed tools recommended
Forming	Can be hot or cold formed
Annealing	788°C (1450°F) × 15 min, air cool
Forging	1065-1176°C (1950-2150°F)
Welding	Rated as good

Applications

Aerospace: High-strength structural components, airframe parts, missile systems
Springs: High-performance springs requiring low density and high strength
Formed Sheet Components: Complex shapes for aircraft and defense applications
General: Components demanding high strength-to-weight ratio with corrosion resistance
