How does eucalyptus wood’s resistance to marine borers compare to teak?

Eucalyptus wood and teak are both popular choices for marine applications, but their resistance to marine borers differs significantly. Teak is renowned for its natural oils and dense grain, which make it highly resistant to marine borers, fungi, and rot. This durability has made teak a preferred material for boat decks and shipbuilding for centuries.

In contrast, eucalyptus wood, while durable and fast-growing, lacks the same level of natural resistance to marine borers as teak. Some eucalyptus species, like blue gum eucalyptus, exhibit moderate resistance due to their tight grain and natural oils, but they generally require chemical treatments or coatings to match teak’s performance in harsh marine environments.

For long-term marine use, teak remains the superior choice, but eucalyptus can be a cost-effective alternative with proper maintenance. Understanding these differences helps in selecting the right wood for marine projects.
