In fact, aluminum only has 60% of the thermal conductivity that copper does. That’s one point for copper. Metal Thermal Conductivity [BTU/(hr·ft⋅°F)] Aluminum: 136: Copper: 231 (Source: Engineer’s Edge) Aluminum vs. Copper: Weight. If you look at the density of the two metals, you’ll notice that aluminum has only about 30% of the ...
Thermal Conductivity . The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity (k) measured in Btu/hr-ft-o F. It is a measure of a substance’s ability to transfer heat through a solid by conduction. The thermal conductivity of most liquids and solids varies with temperature.
°K can be replaced by °C in all of the above since those degrees are the same size. in. is the abbreviation for inch(es), and ft for foot (or feet). kcal is kilocalories. The values of the Btu and calorie are those of the International Table. Very large and very small numbers appear in e-Format and are not spaced. Unvalued zeros on all numbers have been suppressed.
