Key Achievement Timeline
Process Breakthrough in Large-Scale Seamless Rectangular Tubing
We successfully developed high-magnesium 5A06-O rust-proof thin-wall rectangular tubes (240mm x 100mm x 5mm). This project solved critical challenges in dimensional consistency and forming stability for high-corrosion structural applications, reaching international leading standards and entering mass production.
Mass Delivery of Aluminum Tapered Tubes for Rail Transit
Xizhong Aluminum achieved stable batch production of 7020-T6 aluminum reducers (tapered tubes) for high-speed train pantographs. Currently, we are a primary supplier for these China domestic rail transit components.
Manufacturing Ultra-Tight Tolerance Special Profiles
We completed the R&D and acceptance of high-precision 6063-T4 special profiles for new-generation radar systems. The tolerance indicators surpassed Chinese national ultra-high precision standards by 51 times, marking a first-of-its-kind success in the domestic market.
Batch Delivery of Long-Length Precision Tubing
We independently developed high-precision 2A12-T4 thin-wall tubes (up to 7m in length) for UAV (drone) applications. These products achieved international performance benchmarks with rigorous OD and wall thickness control.
Patent Awards & Quality System Expansion
We were granted invention patents for specialized elliptical tapered/tapered tube drawing equipment and processes. Simultaneously, we strengthened our quality framework by achieving IATF 16949 system certification for aluminum bar processing.
Awarded "Top 10 Aluminum Industry Vendor"
Recognized as a premier manufacturer, we continued to expand our aerospace ducting series, including the 5A02 and 5A06 alloy lines.
Upgrade in Large-Scale Thin-Wall Aluminum Ducting Capabilities
We successfully manufactured 5083-O large-diameter thin-wall ducts (φ219mm * 3.0mm) for high-reliability structural and transport applications, further validating our stability in forming large-scale components.
Supporting High-Standard Aerospace Missions
Our 5A06-O ducts successfully met the rigorous launch requirements for the Zhuque-2 (ZQ-2) carrier rocket. Our performance in commercial aerospace projects underscores our engineering-grade delivery capabilities for high-standard missions.
Success in Double-End & Multi-Stage Reducer R&D
We engineered 8-meter long 6061-T6 and 6082-T6 multi-stage reducers (featuring both OD and wall thickness gradients). These are now utilized in high-end engineering machinery to ensure operational stability.
Providing Aluminum Blanks for Aerospace Seating Systems
Xizhong Aluminum currently supplies various specifications of 2024 T3 thin-wall tubes used as structural seating components in the commercial aerospace sector, ensuring high quality and weight-saving performance.
Available in various AMS-grade aluminum alloys, such as AMS 4416B aluminum 2196T8511, AMS 4173G aluminum 6061-T6511/T6510, AMS 4149E aluminum 7175-T74, AMS 4120S aluminum 2024-T4/T351. We support diverse forms including aluminum bars & rods, aluminum tubes, aluminum profiles, and precision forgings tailored to your exact specifications.
