What is GR6 titanium?
Titanium Grade 9 is sometimes referred to as 'half 6-4'. This alloy of titanium with 3% aluminium and 2.5% vanadium offers 20 to 50% greater mechanical strength than the commercially pure (CP) titanium grades, but is more formable and weldable than Ti-6Al-4V (Grade 5).
Increased Palladium
Titanium Grade 18 (UNS R56322) is identical to Grade 9 in all respects with the exception of the additional 0.04 – 0.08% palladium to increase corrosion resistance. Titanium Grades 9 and 18 have a density of 4.48 g/cc - less than 60% that of steel.
Corrosion Resistance
This material offers good corrosion resistance in oxidising, neutral and mildly reducing media, including chlorides. Titanium Grade 18 with the addition of palladium offers greater resistance to corrosion. The alloy resists oxidation up to 600°F (316°C).

Our factory
Our factory specializes in the field of international trade of titanium materials, professionally producing high-quality series products such as titanium tubes, titanium bars, titanium plates, titanium wires, and titanium strips. The factory is equipped with internationally advanced production and testing equipment, including precision forging units, high-speed cold rolling mills, vacuum melting furnaces, CNC spinning machines, continuous drawing production lines, and automated surface treatment systems. Coupled with precision testing instruments such as spectrometers and ultrasonic flaw detectors, we ensure precise control over the entire process from raw materials to finished products. We are committed to providing global customers with titanium products that offer excellent performance and a complete range of specifications through stable and reliable processes and strict quality management, meeting the application needs of high-end industries such as energy, chemical, aerospace, and medical fields.
Titanium product packaging
We place great emphasis on the transportation safety and delivery quality of our products. All titanium materials are packaged using strict industrial-grade solutions: titanium tubes and bars undergo anti-rust treatment, are tightly wrapped with waterproof stretch film, and then placed in reinforced wooden or iron boxes lined with moisture-proof paper, with fillers added to prevent sliding and collisions during transportation. Titanium plates and strips are covered with protective film, fitted with edge protectors, separated layer by layer with moisture-proof paper, loaded onto sturdy wooden or steel pallets, and securely fastened with steel straps. Fine titanium wires are neatly coiled onto specialized spools and encapsulated in sealed boxes that are waterproof and dustproof. Each packaging unit is accompanied by clear product labels, material certificates, and moisture-proof indicators, ensuring that the goods remain intact, clearly labeled, and safely delivered to global customers through long-distance sea freight and multimodal transportation.
