Specific Heat Capacity of Common Magnesium Alloys
The specific heat capacity of magnesium alloys can vary depending on the specific composition of the alloy. The following table provides a comprehensive list of specific heat capacity values for different magnesium alloys at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
