Which one has better heat dissipation, aluminum alloy or red copper?

Aluminum alloy has better heat dissipation performance between aluminum alloy and red copper.

Aluminum alloy is a commonly used heat dissipation material because it has the following heat dissipation advantages:

1. High thermal conductivity: Aluminum alloy has a high thermal conductivity, which can quickly transfer heat from the heat source to the entire material. This allows heat to be transferred faster from the surface of the aluminum alloy to the surrounding environment, improving heat dissipation efficiency.

2. Lightweight: Aluminum alloy is relatively lightweight compared to red copper, which means thinner materials can be used in heat dissipation applications, thereby increasing surface area and contact area, further improving heat dissipation efficiency.

3. High melting point: Aluminum alloy has a high melting point and can withstand the heat dissipation requirements in high-temperature environments.

In contrast, the heat dissipation performance of red copper is relatively poor, mainly due to its lower thermal conductivity. The thermal conductivity of red copper is about half that of aluminum alloy. In addition, red copper is relatively heavy, which limits its application range in some lightweight and high heat dissipation applications.

However, it should be noted that heat dissipation performance is also affected by other factors, such as material thickness, surface treatment, radiator design, etc. Therefore, in specific applications, it is necessary to comprehensively consider the material characteristics and actual needs to choose suitable heat dissipation materials and solutions.
