China is a major producer and consumer of high-strength aluminum alloy materials. In November 2020, China's high-strength aluminum output increased by 8.7% year-on-year to 3.18 million tons. Production in the January-November period increased by 4% to 33.82 million tonnes. High-strength aluminum alloy materials are widely used in transportation, marine, aerospace and other fields, especially in some lightweight key components in the fields of automobiles, aircraft, aerospace, ships, etc., high-strength aluminum alloy materials are irreplaceable.



The marine high-strength aluminum alloy structural plates/profiles developed in my country in recent years that can be commercialized have begun to build their own cruise ships, "sea ranches", drilling platforms, power stations, and helicopter platforms, becoming high-precision materials.
The performance of high-strength aluminum material is seriously underestimated! In fact, from many research results and scientific testing data, we have far underestimated the performance of marine high-strength aluminum alloy structural plates/profiles, and even compared with the performance of steel, high-strength aluminum has great advantages in certain aspects. For example, according to the statistics of the Technical University of Munich, Germany, In the design value of metal strength: the tensile strength of steel Q235 is 195 N/mm², while the high-strength aluminum alloy reaches 210 N/mm².

Compared with the strength design values of the same type of metal materials, the compressive strength of marine high-strength aluminum alloy structural plates/profiles is 210 N/mm², while that of steel is 195 N/mm²; the flexural strength: high-strength aluminum alloy 210 N/mm², steel 195 N/mm²; strength In the standard value, compared with materials of the same model, in terms of yield strength: high-strength aluminum alloy 260 N/mm², steel 235 N/mm²; tensile strength: high-strength aluminum alloy 310 N/mm², steel 265N/mm².
In addition to scientific testing data, after the surface of marine high-strength aluminum alloy structural plates/profiles is oxidized, the appearance will become very beautiful, and it is very resistant to dirt, and it is easy to clean if it encounters oil stains.
