Each has its own advantages. The composite material has higher hardness and is cheaper, while the aluminum-magnesium alloy material has better hardness and is slightly more expensive. Generally speaking, aluminum-magnesium alloy is better.

Reason: The aluminum-magnesium alloy shell performs well in terms of pressure resistance and heat dissipation. Among metal-body notebooks, considering the overall performance, the aluminum-magnesium alloy material is currently the most widely used. Metal materials are not only The strength can reach the extreme of thinness and lightness of the shell, and its excellent heat dissipation performance also contributes to the temperature control of the entire machine. Therefore, in the high-end notebook market, aluminum-magnesium alloy materials have been widely used. If you buy notebooks made of aluminum-magnesium alloy materials, you can not only obtain an efficient and stable safe application environment, but also increase the sense of hierarchy.
