Material Overview
Grade 5 Titanium Alloy (Ti-6Al-4V)
Grade 5 titanium alloy, commonly designated as Ti-6Al-4V, is the most widely used alpha-beta titanium alloy in advanced engineering and scientific research. With 6% aluminum and 4% vanadium as primary alloying elements, this material exhibits an exceptional combination of high specific strength, excellent corrosion resistance, and outstanding thermal stability — properties that make it indispensable for demanding laboratory applications.
RapidKeen's ultra-thin Grade 5 titanium foils are produced through precision cold-rolling processes followed by controlled vacuum annealing, ensuring uniform grain structure, consistent mechanical properties, and minimal surface contamination. Each foil batch undergoes rigorous quality inspection including thickness verification, surface roughness measurement, and compositional analysis to meet the stringent requirements of academic and industrial research laboratories.
Research Grade Quality: Our Grade 5 titanium foils are supplied with material
certification and traceability documentation, suitable for publication-grade experimental research,
prototype development, and material characterization studies.
