The 7-series aluminium alloy is a high-strength alloy series primarily composed of zinc as the main alloying element, often combined with magnesium and copper. These alloys are widely used in environments that demand exceptional strength, excellent fatigue resistance, and moderate corrosion resistance. These characteristics make 7-series aluminium alloys particularly popular in the aerospace and military sectors. 

We have successfully overcome the core "bottleneck" technologies in large-scale aluminium alloy components. From precise control of material composition to innovative casting and processing techniques, we have developed a unique system of technological advantages. This breakthrough addresses three long-standing challenges in the industry and unlocks new possibilities for aluminium alloy applications on a broader scale.
