GR4 Titanium Plate (Grade 4 Titanium Plate)

Grade 4 Titanium Plate, also known as GR4 Titanium Plate, is the strongest of the commercially pure titanium grades. It offers an excellent balance of high strength, good corrosion resistance, and formability. Compared to other commercially pure grades like Grade 1, 2, and 3, Grade 4 titanium provides superior tensile strength while maintaining good weldability and ductility. This makes it a popular choice for high-performance applications in aerospace, marine, chemical processing, and industrial fields.
