In the aerospace field, aluminum based silicon carbide composite materials are highly favored due to their excellent high temperature resistance and lightweight properties. Its temperature resistance can reach over 500 ℃, reducing weight by 40% compared to traditional nickel based alloy materials, while improving fuel efficiency by 15%. This characteristic makes aluminum based silicon carbide an ideal material for manufacturing aircraft engine components, aircraft fuselage, satellite structural components, and more. For example, it can be used to manufacture key components such as turbine blades and combustion chamber liners, as well as to process satellite structural components such as antenna brackets and reflector substrates, ensuring dimensional stability under extreme temperature differences.

2、 Automotive field
In the automotive industry, aluminum based silicon carbide composite materials are also widely used. It can be used not only for manufacturing engine components, transmission components, brake system components, but also for manufacturing lightweight vehicle bodies. Due to its excellent corrosion resistance and high strength, aluminum based silicon carbide can replace traditional steel materials in these components, thereby improving their durability and fuel efficiency. Especially in the field of new energy vehicles, the application of aluminum based silicon carbide has promoted the combination of high efficiency and lightweight of electric drive systems. For example, when the motor housing is made of aluminum based silicon carbide, the heat dissipation efficiency is increased by 40% compared to aluminum alloy, effectively extending the battery life. At the same time, the wear resistance of the brake disc reinforced with silicon carbide particles is doubled, the braking distance is shortened by 10%, and the safety performance of the car is improved.

3、 Electronic field
In the field of electronics, aluminum based silicon carbide composite materials have become specialized packaging materials for electronic components due to their excellent thermal and electrical properties. It can composite aluminum with high volume fraction silicon carbide to form a low-density, high thermal conductivity, and low expansion coefficient packaging material, thereby solving the thermal failure problem of electronic circuits. In addition, aluminum based silicon carbide can also be used to manufacture high-frequency signal transmission lines, integrated circuit packaging, electronic component heat sinks, and so on. These applications not only improve the heat dissipation and circuit stability of electronic products, but also promote further development of electronic technology.
