Titanium 15-3 (Ti 15-3-3-3)

Advanced Structural Performance of Ti-15V-3Cr-3Sn-3Al

Ti-15V-3Cr-3Sn-3Al, commonly known as Ti 15-3-3-3, is a beta titanium alloy designed for extreme-performance environments. This alloy contains 15% vanadium, 3% chromium, 3% tin, and 3% aluminum. It delivers high strength, excellent formability, and consistent performance across complex applications.


Unlike traditional alpha-beta alloys like Grade 5, Ti 15-3-3-3 offers outstanding cold formability and weldability. It performs reliably even after forming and allows for highly precise machining, making it a material of choice for aviation and defense structures. The alloy is typically available in sheet, plate, tube, and extrusion forms.


Thanks to its low specific gravity and superior strength-to-weight ratio, Ti 15-3-3-3 is widely used in parts such as aircraft springs, brackets, frames, and internal engine components. It is stronger than aluminum, lighter than steel, and resistant to corrosion, which makes it ideal for aerospace applications demanding both durability and lightweight performance.


Sustainable Demand Across Aerospace and Civil Industries

As global aerospace manufacturers pursue fuel efficiency and compliance with environmental regulations, demand for lightweight titanium alloys continues to rise. Ti 15-3-3-3 meets these needs and is now being adopted in civil sectors as well. Its use is expanding into electric vehicle components, drone frames, medical device parts, and high-end sports equipment.


Unlike many beta titanium alloys, Ti 15-3-3-3 offers exceptional cold working capabilities. Manufacturers can form intricate shapes through cold rolling, drawing, and stamping. This flexibility makes it ideal for high-precision components that demand structural reliability.


At Dong-A Special Metals, we recognize Ti 15-3-3-3 as a strategic alloy that aligns with global lightweighting and sustainability trends. We support its recycling from high-grade scrap, contributing to a greener metal resource cycle. As industries aim for reduced emissions and enhanced performance, this alloy stands out as a key material for the next generation of advanced manufacturing.
