Pure copper is also called red copper and purple red. Because the copper sheet is exposed to the air, the surface will inevitably become blackened by oxidation, but it does not affect the heat dissipation effect. For example, you can check the surface of the copper plate with fine sandpaper or toothpaste. Because the CPU and GPU graphics cards inside the notebook computer use thermally conductive plastic to conduct heat, the thermally conductive plastic is prone to aging at high temperatures for a long time, and eventually loses its function, causing the CPU or GPU to overheat, and the laptop cannot start after overheating. But with this copper heat sink, the heat dissipation problem caused by frequent crashes such as notebook computers can be solved.
