(1) metal material

4. Low-cost and high-performance metal composite processing and molding technology.

New materials and structural parts made of metals and various materials that have obvious advantages in high pressure resistance, wear resistance, corrosion resistance and improving electrical conductivity and thermal conductivity, and new technology of copper-aluminum composite pipe for heat exchanger; Low density, high strength, high elastic modulus, anti-fatigue particle reinforcement, fiber reinforced aluminum matrix composite industrial molding technology and low cost and high performance reinforcing agent production technology.

If these patents are a little too simple, I hope they can help you.
