Ipe vs Mahogany

Yes — dramatically. Ipe's Janka hardness is 3,680 lbf compared to Mahogany's 800–1,220 lbf depending on species. Ipe is roughly 3–4 times harder, making it far more resistant to dents, scratches, and surface wear from foot traffic and furniture.

It can, but it's not ideal. Mahogany is significantly softer and less dense than Ipe, requiring more frequent sealing and maintenance. It will last 10–20 years outdoors compared to Ipe's up to 75+ years. In humid or coastal climates, Mahogany degrades even faster.

Ipe costs more upfront per board foot, but its dramatically longer lifespan makes it far less expensive over time. You would replace a Mahogany deck 3–4+ times before an Ipe deck needs replacing — and each replacement includes labor, permits, and weeks of construction disruption.

Yes — significantly. Mahogany requires regular sealing and staining (typically annually) to protect against moisture, UV damage, and decay outdoors. Ipe needs only an optional UV oil if you want to maintain its brown color; otherwise it ages gracefully to silver-grey with no treatment required.

Often not. Genuine Mahogany (Swietenia macrophylla) is CITES-listed and heavily regulated due to over-harvesting. Much of what's sold as 'Mahogany' today is actually African Mahogany (Khaya spp.) or other look-alike species, which may have different durability characteristics. Ipe, by contrast, is consistently the same species with well-documented performance data.

Ipe is far better for marine and dock applications. Ipe naturally resists marine borers, saltwater, and constant moisture exposure. Mahogany lacks natural resistance to marine borers and will deteriorate much faster in waterfront environments.
