Nano-ceramic aluminium alloy is a kind of multi-item solid material, which is based on aluminium or aluminium alloy by physical or chemical methods and composed of one or more reinforcing substances with different properties. This material not only has the advantages of high plasticity of aluminium alloy matrix, but also has the advantages of high hardness and high modulus of reinforcing particles. Therefore, nano-ceramic aluminium alloy has good comprehensive properties and can be widely used in aerospace, electronics and electric, automobiles and other fields. In this paper, a kind of in-situ self-generated nano-ceramic particles in aluminium alloy matrix by chemical method is introduced. The nano-ceramic aluminium alloy prepared by this method has the advantages of light weight, high rigidity, high strength, high fatigue resistance, high temperature resistance, and its mechanical properties are much higher than those of aluminium alloy, while maintaining good processing and manufacturing properties of aluminium alloy.
