The development and progress of aluminum alloy preparation technology has driven the rapid development of aluminum industry
which plays a very important role in the national economy.Based on the international patent database of Derwent Innovations Index
the development and application progress of aluminium alloy technology patent were analyzed by TDA analysis tool.The results show that the patent and core patents of aluminum alloy are mainly concentrated in Japan
USA and China etc.The development direction of aluminium alloy patent technology mainly focuses on specific alloy type
alloy product structure
and the improvement of product performance through heat treatment.In recent years
the hot research and development directions are interested in aluminum alloy coatings
alloy components complication and alloy functional diversification etc.
