Ti-15V-3Al-3Cr-3Sn Titanium Foil Description
1. Introduction
Ti-15V-3Al-3Cr-3Sn titanium foil is an ultra-thin near-β titanium alloy strip developed for high-end precision manufacturing.
It is produced via vacuum melting, hot rolling breakdown, multi-pass precision cold rolling and solution & aging heat treatment (Complex forming is performed in the solution-treated state, while final high strength is achieved in the aged state, enabling control over processing and performance).
The key advantage of this material is its formability and end-use strength can be controlled separately as required.
In practical engineering applications, different titanium materials exist some differences:
- Gr1 Titanium Foil: highest ductility, the lowest strength, applyfor extreme forming operations
- Gr2 Titanium Foil: well-balanced overall properties, suitable for general industrial applications
- Gr4 Titanium Foil: the highest strength among pure titanium grades, with improved load-bearing capacity but increased processing difficulty
- Gr5 Titanium Foil: a high-strength structural material, difficult to cold-form
- Ti-10V-2Fe-3Al Titanium Foil: Complex forming is performed in the solution-treated state, while final high strength is achieved in the aged state, enabling control over processing and performance.
