Grade 23 Titanium/Aluminum/Vanadium Alloy Powder (Ti90/Al6/V4)

Grade 23 Titanium/Aluminum/Vanadium Alloy Powder (Ti90/Al6/V4) is an extra-low interstitial (ELI) titanium alloy powder, known for its excellent toughness, corrosion resistance, and superior fatigue strength compared to standard Ti-6Al-4V. The powder form, particularly with controlled particle size distribution and morphology, ensures consistent performance in additive manufacturing and powder metallurgy processes. This alloy powder is widely used in aerospace, biomedical, and energy industries, where high strength, low weight, and long-term durability are required. Specific applications include laser powder bed fusion for aerospace turbine components, 3D-printed orthopedic implants with optimized porous structures, and chemical reactor parts demanding resistance to corrosive media. In research, Grade 23 powder is at the forefront of investigations into powder recycling, spatter control, and surface modification strategies to enhance fatigue life and biocompatibility. Its unique balance of processability, biocompatibility, and fatigue resistance ensures continuing significance in advanced scientific and industrial applications.
