Entity Definition

What is Grade 19 Titanium (Ti-10V-2Fe-3Al)?

Grade 19 (Ti-10V-2Fe-3Al) is a beta-rich titanium alloy developed specifically for high-strength forged components. Its deep hardenability allows uniform mechanical properties through thick sections — a critical advantage over alpha-beta alloys that exhibit property gradients in heavy cross-sections. It achieves tensile strengths up to 1,240 MPa (180 ksi) with good fracture toughness.
