Specific Heat Capacity of Common Titanium Alloys
The specific heat capacity of titanium alloys can vary depending on the specific composition of the alloy. However, in general, titanium and its alloys have relatively low specific heat capacities compared to some other metals.
The following table provides a curated list of specific heat capacity values for common titanium alloys, taken at room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
