Material Coefficient of Linear Expansion (10⁻⁶/K) Typical Application Consideration Aluminum 23 Requires flexible connectors in piping systems Steel 12 Common structural steel used in construction Copper 17 Thermal expansion in electrical wiring Glass (Borosilicate) 3. This subtle increase in average separation manifests as a measurable growth in length along a specific axis.
This complexity allows for the design of structures that maintain stability under complex thermal gradients. The formula ΔL = α × L₀ × ΔT provides a practical method to predict elongation, where L₀ represents the original length and ΔT is the temperature difference.
