Thermal conductivity of magnesium alloy:
At minus 18 degrees, the thermal conductivity of magnesium is 155.7W/(M.K), at 0 degrees, the thermal conductivity is 155.3, at 20 degrees it is 154.5, at 38 degrees it is 154.1, at 93 degrees it is 153.7, at 149 degrees it is 153.2, at 204 degrees it is 152.8, at 260 degrees 152.8, 316 degrees 153.2, 371 degrees 153.7, 427 degrees 154.1, 482 degrees 154.9W/(M.K).
Thermal conductivity of aluminum alloy:
at 25 degrees Celsius, the thermal conductivity of aluminum alloy 1070: 1070 236W/(m*k), at 20 degrees Celsius, the thermal conductivity of aluminum alloy 1050: 1050A 231W/(m*k).
The thermal conductivity of different substances is different; the thermal conductivity of the same substance is related to its structure, density, humidity, temperature, pressure and other factors. When the water content of the same substance is low and the temperature is low, the thermal conductivity is small.
Is the thermal conductivity of magnesium alloy higher than that of aluminum alloy?
From the numerical point of view, the room temperature thermal conductivity of magnesium alloy is 154.5, which is higher than that of aluminum alloy, which is 151W/(M.K), so does it mean that the heat dissipation of magnesium alloy is better?
Magnesium alloy or aluminum alloy, which material dissipates heat better?
The heat dissipation of magnesium alloy has a considerable advantage compared with that of aluminum alloy. For radiators of magnesium alloy and aluminum alloy materials with the same volume and shape, the heat (temperature) produced by a certain heat source is easier for magnesium alloy to be dissipated by heat dissipation than aluminum alloy. The speed at which the root of the slice is transferred to the top, and the top is more likely to reach high temperatures.
