Emissivity Values: granite natural surface
Thermal emissivity and solar absorptivity values for engineering materials — includes temperature-dependent emissivity for metals and nonmetals (100 K to 2500 K), ambient-temperature emissivity for building and industrial materials, and solar radiative properties (solar absorptivity alpha_S) for solar-energy and heat-transfer calculations
| material id | category | emissivity max (dimensionless) | emissivity min (dimensionless) | material |
