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.

Nano-titanium diboride particle reinforced aluminum matrix composite material is a kind of discontinuous reinforced metal matrix composite material with the fastest development and widest application prospect in the world in the past 20 years. It is considered to be an ideal lightweight structural material. In particular, it has broad application prospects in key products such as motor vehicle engine pistons, cylinder heads (cylinder heads), and cylinder blocks and in the aviation industry, especially in the field of 3D printing of aluminum alloy parts.

Compared with silicon carbide particles, nano-titanium diboride particles have better wettability of titanium diboride and aluminum alloys, and are easier to distribute evenly in aluminum alloy solutions, and the effect of particle reinforcement is better.
