GR5 Titanium Plate – High-Performance ASTM B265 Ti-6Al-4V Sheet
Jan 15, 2026
What is GR5 titanium?
GR5 Titanium Plate, also known as Ti-6Al-4V plate, is a high-strength, lightweight titanium alloy product that meets the ASTM B265 specification for titanium and titanium alloy plates, sheets, and strips. Composed of 90% titanium, 6% aluminum, and 4% vanadium, it is the most commonly used titanium grade in both aerospace and medical industries.
With a superior strength-to-weight ratio, excellent fatigue resistance, and outstanding corrosion resistance, the GR5 Titanium Plate is widely used in demanding environments, including aircraft structures, medical implants, marine equipment, pressure vessels, and performance automotive parts. It offers a unique combination of mechanical properties and biocompatibility, making it one of the most versatile materials available for high-performance engineering applications.
