Model No: Ti-13V-11Cr-3Al
Ti-13V-11Cr-3Al Titanium Alloy Bar
Ti-13V-11Cr-3Al is the first metastable β-type high-strength titanium alloy to achieve practical industrial application. Its high strength is achieved through solution and aging treatments. In aircraft structural manufacturing, the use of Ti-13V-11Cr-3Al titanium alloy rods reduces aircraft weight by approximately 10%, making it a favorite alloy in the aerospace industry for its lightweight and high-performance properties.

Ti-13V-11Cr-3Al Titanium Alloy Bar Product Introduction
Ti-13V-11Cr-3Al is the first metastable β-type high-strength titanium alloy to achieve practical industrial application. Its high strength is achieved through solution and aging heat treatments.
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. Lork Group 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.

Ti-13V-11Cr-3Al Titanium Alloy Fabrication and Heat Treatment
Machinability
Grade Ti-13V-11Cr-3Al alloy is hard to machine but can be successfully done using slow speeds, high coolant flow, and high feed rates. Tooling should be performed using tungsten carbide designations C1-C4 or cobalt type high speed tools.
Forming
Grade Ti-13V-11Cr-3Al alloy can be hot or cold formed.
Annealing
Full annealing of this material can be performed by heating to 788°C (1450°F) for 15 min and then air cooled.
Forging
Forging can be performed at 1065-1176°C (1950-2150°F).
