Thermal Conductance
Thermal conductance is a measure of how easily heat flows through a material or object when there is a temperature difference across it. In simple terms, it tells us how good something is at letting heat pass through. The higher the thermal conductance, the more efficiently heat is transferred; the lower the thermal conductance, the more the material resists heat flow.
In fastener and mechanical applications, thermal conductance is important because it influences how heat spreads through joints, bolts, washers, and connected assemblies. Good thermal conductance helps prevent localized overheating, while poor conductance may cause thermal stress or uneven expansion.
