Ti64 Grade 23 (Ti-6Al-4V ELI)
Overview:
Ti64 Grade 23 (Ti-6Al-4V ELI) is a high-strength, lightweight titanium alloy engineered for demanding aerospace, medical, motorsports, and industrial applications. The designation “ELI,” which stands for Extra Low Interstitials, indicates that this alloy has improved ductility and fracture toughness compared to standard Grade 5 titanium, while still offering exceptional strength-to-weight performance. Ti64 Grade 23 is known for its outstanding corrosion resistance, excellent fatigue properties, and biocompatibility, making it one of the most widely used materials in additive manufacturing for critical performance components. Its capability to maintain mechanical integrity under high stress, elevated temperatures, and harsh environments makes it ideal for production-grade applications where reliability and weight reduction are essential.
Applications:
Ti64 Grade 23 is commonly utilized in aerospace brackets, lightweight structural components, heat exchangers, motorsports hardware, orthopedic implants, surgical instruments, fluid handling systems, turbine components, and high-performance industrial assemblies. This material is especially valuable for applications that require high strength combined with reduced mass, corrosion resistance, and long-term fatigue performance. In additive manufacturing, Ti64 Grade 23 is often chosen for topology-optimized geometries, lattice structures, and consolidated assemblies that cannot be produced efficiently through traditional machining methods.

Excellent (Rating A):
Ti64 Grade 23 offers outstanding corrosion resistance against saltwater, chlorides, body fluids, fuels, hydraulic fluids, oils, alkalis, nitric acid, and most corrosive industrial environments. Its exceptional durability is attributed to a stable titanium oxide surface layer that provides excellent protection against oxidation and galvanic corrosion in challenging operating conditions.
Good/Fair (Rating B):
Ti64 Grade 23 performs well in environments with organic acids and elevated temperature oxidation, but it experiences limited exposure to reducing acids. Prolonged contact with highly concentrated acids at elevated temperatures may gradually compromise the surface integrity.
Poor (Rating C):
Titanium is highly susceptible to aggressive attack by hydrofluoric acid, concentrated hydrochloric acid, concentrated sulfuric acid, and strong reducing acids. These substances can significantly compromise the structural integrity of titanium.

Excellent (Rating A):
17-4PH stainless steel offers excellent corrosion resistance in humid, marine, and chemically exposed environments. It withstands water, saltwater, fuels, hydraulic fluids, oils, weak acids, alkalis, and various industrial chemicals while maintaining high mechanical strength and wear resistance.
Good/Fair (Rating B):
This material is suitable for organic acids, food processing chemicals, mild chlorides, and moderate exposure to acidic environments. However, long-term exposure to highly concentrated chlorides or elevated temperature corrosive conditions may increase the risk of localized corrosion or stress corrosion cracking.
Poor (Rating C):
17-4PH stainless steel has poor resistance to strong acids (such as hydrochloric and sulfuric acids), chlorinated solvents, and highly aggressive chloride environments, which can compromise its corrosion resistance and accelerate pitting or cracking.
