Ti-15V-3Al-3Cr-3Sn Titanium Foil

Aerospace Ti-15V-3Al-3Cr-3Sn Titanium Foil Description

1. Introduction

Aerospace Ti-15V-3Al-3Cr-3Sn Titanium Foil is a high-strength near-beta titanium alloy foil designed for advanced aerospace applications, manufactured under AMS aerospace material standards. It is produced through vacuum melting, multi-step thermo-mechanical processing, precision rolling, and controlled heat treatment to achieve ultra-high strength, excellent hardenability, and stable microstructure. Compared with Gr5 (Ti-6Al-4V), Ti-15V-3Al-3Cr-3Sn provides significantly higher strength after aging, making it suitable for critical lightweight and high-load aerospace structures.

Benefits in Aerospace Use

  • Ultra-high strength after aging treatment, suitable for extreme load-bearing aerospace parts.
  • Excellent hardenability enables deep strength control through heat treatment.
  • High strength-to-weight ratio supports advanced lightweight structural design.
  • Good fatigue resistance ensures reliable performance under cyclic stress and vibration.
  • Good fracture toughness for a high-strength alloy, improving structural safety margin.
