In modern industry, aluminum plate has become the material of choice across various sectors for its lightweight, high strength, and corrosion resistance. As a professional manufacturer deeply engaged in aluminum processing, we proudly offer high-quality aluminum plate produced in strict compliance with the ASTM B209 standard. Leveraging our internationally certified process system and comprehensive quality control, we provide comprehensive solutions for global customers in applications ranging from aerospace to architectural decoration.

The Technical Essence of the ASTM B209 Standard
ASTM B209, an internationally recognized standard for aluminum and aluminum alloy sheet, covers alloys from the 1xxx to 8xxx series and encompasses 12 core specifications, including chemical composition, mechanical properties, and surface treatment. For example, 6061-T651 alloy boasts a tensile strength of 310 MPa, a yield strength of 276 MPa, and an elongation of 8%, providing both structural rigidity and fatigue resistance. Our production line strictly adheres to the requirements of ASTM B209-14, using direct-emission spectrometers to test elements such as Si and Mg at the ppm level to ensure chemical composition deviations within ±0.01%. In terms of mechanical properties, our 2024-T351 aluminum sheet undergoes a pre-stretching process, reducing internal stress by over 90% and achieving a flatness of ±0.05mm/m, far exceeding the industry average. This high-precision feature makes it the material of choice for precision applications such as aerospace fixtures and fixtures and semiconductor device substrates.

Full-Process Quality Control System
- Raw Material Traceability
We use imported electrolytic aluminum ingots, and a pre-furnace rapid analysis system monitors impurity levels in real time to ensure Fe ≤ 0.35% and Cu ≤ 0.10% (using 5052 aluminum alloy as an example). Each batch of raw materials is accompanied by an SGS test report, ensuring full traceability from mine to final product.
- Intelligent Production Process
We have introduced a 2800mm hot rolling line from SMS Germany. Using AI algorithms to optimize rolling parameters, we achieve a thickness tolerance of ±0.03mm. A fully automated aging furnace is used for heat treatment, and the grain size of our 6061-T6 aluminum plate products is controlled to ASTM Grade 8 or above, ensuring stable mechanical properties.
- Multi-Dimensional Inspection System
Non-destructive Testing: Equipped with GE ultrasonic testing equipment from the United States, each sheet is scanned 100% of the time, with a defect detection rate exceeding 0.3mm.
Surface Treatment: Anodizing produces a film thickness of 15-25μm, and the product withstands over 1,000 hours of salt spray testing with no corrosion.
Dimensional Accuracy: Laser thickness gauges monitor the product in real time, ensuring a width tolerance of ±0.5mm and a length tolerance of ±1.0mm.
