Grade 9 Ti-3Al-2.5V Titanium Plate Sheet
What is grade 9 titanium?
Grade 9 titanium, also known as Ti-3Al-2.5V, is a near-alpha titanium alloy offering a balanced combination of strength, corrosion resistance, and formability. Its properties lie between the commercially pure titanium grades (Grades 1-4) and high-strength titanium alloys like Grade 5 (Ti-6Al-4V). Grade 9 is particularly valued in applications requiring higher strength than CP titanium but with better weldability and formability than Grade 5.
