What are the thermal expansion coefficients of eucalyptus versus teak wood?

The thermal expansion coefficients of eucalyptus and teak wood are important factors to consider in woodworking and construction, as they determine how the wood responds to temperature changes. Eucalyptus wood typically has a higher thermal expansion coefficient compared to teak wood. On average, eucalyptus wood expands and contracts more significantly with temperature fluctuations, with a coefficient ranging between 0.000045 to 0.000055 per °C. In contrast, teak wood, known for its stability, has a lower thermal expansion coefficient, usually around 0.000035 to 0.000045 per °C.

This difference makes teak wood a preferred choice for applications where dimensional stability is critical, such as outdoor furniture, flooring, and boat building. Eucalyptus, while durable, may require more careful consideration in environments with extreme temperature variations. Understanding these properties helps in selecting the right wood for specific projects, ensuring longevity and performance.
