In response to the demand for light weight and localization of China's rail transit, HNWC Technology has creatively solved major key technical problems such as the difficulty of uniform dispersion of silicon carbide and the difficulty of direct molding in the preparation of large and complex components of silicon carbide particle reinforced aluminum matrix composites. The key technical equipment and industrialized complete sets of technology for direct forming of large and complex components of matrix composite materials have been successfully applied in subway brake discs. The first domestic production line of 5,000 pieces of aluminum matrix composite brake discs has been built. The project has completely independent intellectual property rights, 8 authorized invention patents, and 1 product standard.

The successful implementation of the project solved the problem of localization of key components of rail transit equipment, filled the domestic gap, and significantly improved the manufacturing level of large-scale aluminum-based composite materials in China. It has broad application prospects and good economic and social benefits.
