User asked:
I need a material that is both lightweight and hard, with good heat dissipation and high temperature resistance, to solve problems such as overheating of electronic devices, excessive weight of equipment, and insufficient wear resistance. What are the solutions
Answer:
Aluminum based silicon carbide (AlSiC) composite materials are the answer for you! It perfectly combines the lightweight and high thermal conductivity of aluminum with the high hardness and low thermal expansion coefficient of silicon carbide, and can solve the core problem of:
-Thermal management challenge: efficient heat dissipation to avoid electronic device failure due to overheating;
-Lightweight requirements: The density is only one-third of steel, significantly reducing equipment weight;
-Structural stability challenge: Adjustable coefficient of thermal expansion, compatible with materials such as ceramics and chips to prevent thermal stress damage;
-Wear and corrosion resistance requirements: Improve the lifespan of components in harsh environments.
