Looking ahead, in pursuit of global goals for more economical, environmentally friendly, and safer aviation, the development of aerospace aluminum panels will increasingly focus on "multi-performance synergistic optimization" —moving beyond the singular pursuit of strength or lightweight, and instead achieving a comprehensive optimal solution through integrated material-structure-process design, encompassing weight reduction, extended service life, cost efficiency, and maintainability.
The selection of marine materials involves not only technical and cost considerations but also legal liabilities and life safety. For shipbuilders, using aluminum alloy plates certified by classification societies is not just a legal requirement but also a demonstration of corporate social responsibility and brand credibility. For material manufacturers, obtaining classification society certification signifies entry into the high-end supply chain of the global shipbuilding industry, which demands continuous technological investment and quality commitment. With the development of the marine economy, the marine aluminum alloy market will continue to grow, and technological innovation and quality control will become key factors in market competition.
The evolution of marine aluminum alloy ship plates epitomizes humanity's relentless pursuit of maritime exploration and conquest. Like a sturdy yet lightweight "silver armor," it safeguards vessels' safe and cost-effective navigation through the vast ocean. With the booming development of "blue economy" sectors such as deep-sea exploration and offshore renewable energy, this marine-engineered specialty material is poised to expand its applications into even more expansive blue territories.
As winter gives way to spring, all things renew. On December 12,2025, Hengshi Hui (Nanjing) New Material Technology Co., Ltd. hosted its 2025 New Year Gala at Suning Global Hotel. Chairman Chen Baohui summed up the experience and lessons of 2025 and expressed new expectations for 2026.
In extrusion manufacturing, dimensional tolerance control involves multiple factors including die design, ingot quality, equipment precision and process parameters. Among these, extrusion speed is the most dynamic and challenging variable to stabilize. The impact of extrusion speed on dimensional tolerance exhibits a dual mechanism: Firstly, speed variations directly alter the flow state of metal at the die working zone, affecting the profile's geometry. Secondly, speed fluctuations induce changes in deformation thermal effects, leading to temperature variations at the die exit and subsequently influencing post-cooling shrinkage. These two mechanisms interact synergistically, resulting in nonlinear characteristics of speed's influence on tolerance. A thorough understanding of this coupling mechanism forms the theoretical foundation for achieving precise tolerance control.
Aluminum alloy extrusion dies serve as the core technical equipment in profile manufacturing, accounting for 10%-15% of total extrusion production costs. During extrusion processes, dies endure preheating temperatures ranging from 450-500°C, unit pressures reaching 500-600MPa and intense friction caused by aluminum alloys under high-temperature and high-pressure conditions. Such extreme operating conditions inevitably lead to die wear, with die lifespan directly impacting production efficiency, product quality and economic performance of aluminum processing enterprises. Therefore, gaining in-depth understanding of die wear mechanisms, identifying key factors affecting die longevity and establishing systematic lifespan extension technologies are crucial for aluminum processing industries.
