Fabrication & Procurement Notes
Availability: Grade 6 is less common than Grades 2 or 5. It is typically produced to order in specific forms (plate, sheet, bar, forgings) rather than held in large general inventory.
Machining & Forming: Its machining characteristics are similar to other titanium alloys-requiring sharp tools, slow speeds, and ample coolant. Its alpha structure makes it less formable than CP grades but adequate for many shapes.
Specifications: It conforms to standards such as AMS 4916, AMS 4927, and ASTM B265.

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.
