Abstract
Non-ferrous metals are the basic strategic materials for national industrial manufacturing. Exploring the development process of the industry and identifying generic technologies in the field play a vital role in breaking through the technical bottleneck of the non-ferrous metal industry and achieving transformation and upgrading. This paper selects Derwent patent database as the data source, uses CiteSpace software to construct a visual map of the retrieved non-ferrous metal industry patent data, identifies and analyzes the generic technologies and hot fields of the non-ferrous metal industry, and puts forward reasonable suggestions for the future development of the industry.
