WebFeb 13, 2024 · The coefficients of linear and volumetric expansion are rates at which a material expands. For isotropic materials, these two coefficients are related: b = 3a. You can find below a list of the most common linear expansion coefficients. Aluminum: 22.2×10⁻⁶ 1/K; Concrete: 14.5×10⁻⁶ 1/K; Copper: 16.6×10⁻⁶ 1/K; Glass: 5.9×10⁻⁶ 1/K WebJan 14, 2024 · From the definition of the expansion coefficient, the change in the linear dimension ΔL over a temperature range ΔT can be estimated to be: ΔL L = αLΔT. This equation works well as long as the linear-expansion coefficient does not change much over the change in temperature. If it does, the equation must be integrated.
