On June 16, the AVIC's six-brand shipbuilding titanium alloy standard parts localization project successfully completed a joint technical review conducted by the Institute of Metal Research, the main user units, and the design teams from the Chinese Academy of Sciences. This milestone marks six years of dedicated R&D efforts, culminating in the approval of a new marine titanium alloy standard parts process plan and summary—officially granting permission to proceed with the production of physical components.
Marine titanium alloy standard parts are designed for large-scale applications, requiring high clamping force, strong shear resistance, and superior corrosion resistance, exceeding even the standards set for aerospace fasteners. As a leading research institution in China for marine titanium alloy fasteners, the aviation standard company has successfully passed the process review for 18 marine titanium alloy products, leveraging its long-term expertise in aviation titanium alloy standard parts and the phased achievements in domestic titanium alloy material development.
During the process evaluation meeting held in Guiyang on June 16, the review panel listened to the navigation mark company’s report on the new work process plan and process summary. They thoroughly examined all development documentation and conducted detailed reviews of processing and inspection procedures. At the site, the team unanimously approved the process plan for the six standardized domestic titanium alloy materials used in marine standard parts, allowing the company to move forward with actual product manufacturing.

This achievement represents a significant step forward in the localization of critical marine components, enhancing China's self-reliance in advanced materials technology and supporting the country’s growing maritime industry. The successful review not only validates the technical capabilities of the involved organizations but also sets a solid foundation for future developments in this crucial sector.
