In terms of mechanical properties, Cr2AlC has high hardness, strength, and toughness, which enables it to maintain good mechanical properties even in high temperature environments, making it suitable for manufacturing wear-resistant and impact resistant components. In addition, its anti fatigue performance has also been recognized by researchers, which has potential application value in fields such as aviation, aerospace, and automotive industry. 

In terms of thermal performance, Cr2AlC exhibits excellent thermal stability and thermal conductivity, making it an ideal material for high-temperature heat exchangers and thermal protection systems. Meanwhile, due to its low coefficient of thermal expansion, Cr2AlC has good dimensional stability under temperature changes, which can effectively reduce thermal stress and minimize structural damage caused by thermal expansion. 

In terms of electrical performance, the conductivity of Cr2AlC is between that of metals and semiconductors, and it has a certain degree of electrochemical stability, which makes it potentially applicable in the fields of electronic devices and energy storage, such as as as battery electrode materials or substrate materials for high-temperature electronic devices. 

Antioxidant performance: The oxide layer formed on its surface can effectively prevent further oxidation and protect the material from corrosion in high-temperature environments, which is crucial for high-temperature structural materials. 

Packaging and storage: This product is packaged in an inert gas filled plastic bag, sealed and stored in a dry and cool environment. It should not be exposed to air to prevent moisture and oxidation aggregation, which may affect dispersion performance and usage effectiveness.
