BT16 (БТ16)
BT16 Titanium Alloy for Aerospace, Defense and High-Load Fasteners
BT16 Titanium (ВТ-16) is a high-strength α+β titanium alloy developed for parts that require excellent mechanical strength, fatigue resistance, and reliable corrosion performance. It is commonly used for fasteners and threaded parts as well as aerospace and industrial components where light weight and long service life under cyclic loading are critical. Russian Metals supplies BT16 titanium with quality documentation and processing support based on project requirements.
Why BT16 Titanium is Preferred for High-Performance Components
High Strength and Durability: BT16 provides a strong balance of strength and toughness, supporting reliable performance under dynamic and vibration-heavy conditions.Excellent Fatigue Resistance: Designed for repeated stress cycles, making it suitable for critical fasteners and structural components.
Good Corrosion Resistance: BT16 performs well in humid, marine, and industrial environments, helping protect components from premature degradation.
Production-Friendly: The alloy is used in wrought product forms and is suitable for manufacturing threaded parts and engineered components where consistent mechanical properties are required.
