1 Hydraulic conductivity, a property of a porous material's ability to transmit water. 2  Thermal conductivity, the intensive property of a material that indicates its ability to conduct heat.  Rayleigh conductivity, describing the behavior of apertures concerning the flow of a liquid or gas.
Thermal conductivity of gases, insulation products, aluminum, asphalt, brass, copper, steel and other common materials. Thermal conductivity is a material property describing the ability to conduct heat. Thermal conductivity can be defined as. the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions.
