概述
Ti6Al4V titanium alloy block (Grade 5, UNS R56400) is the world's most widely used titanium alloy, combining steel-level strength with 40% less weight. With 6% aluminum and 4% vanadium in an alpha-beta structure, it delivers a tensile strength of ≥895 MPa, outstanding corrosion resistance in seawater and chemicals, and excellent biocompatibility. Supplied to ASTM B348 / AMS 4928 in 10-300mm thickness with EN 10204 3.1 certification. Ideal for aerospace structures, medical implants, marine hardware, and high-performance industrial components.
描述（英文）
Ti6Al4V titanium alloy block (Grade 5, UNS R56400) is an alpha-beta titanium alloy containing 6% aluminum and 4% vanadium. It is the most widely used titanium alloy in the world, accounting for about 50% of total titanium usage. It offers an exceptional strength-to-weight ratio — steel-level strength at 40% less weight — combined with outstanding corrosion resistance in seawater and chemical environments, and excellent biocompatibility. Supplied to ASTM B348 and AMS 4928 in annealed condition with a minimum tensile strength of 895 MPa and full EN 10204 3.1 certification. Available in thicknesses from 10mm to 300mm, it is ideal for aerospace structural parts, medical implants, marine components, chemical processing equipment, and high-performance industrial applications.
