Nano-titanium diboride (Nano-TiB2) particle reinforced aluminum matrix composite material, TiB2/Al has excellent mechanical properties and physical properties such as high specific strength and specific modulus, wear resistance, fatigue resistance, low density, good dimensional stability, etc. Moreover, compared with continuous fiber reinforced composite materials, it has a significant low-cost advantage. The material is isotropic, easy to process, and flexible and diverse in preparation. It can be extruded, rolled and forged with traditional equipment.
