Massaranduba: The Underrated Tropical Hardwood You Should Know

Massaranduba: A Hidden Gem

While Ipe and Cumaru dominate the tropical hardwood conversation, Massaranduba (Manilkara bidentata) — commonly marketed as Brazilian Redwood — quietly delivers some of the most impressive performance metrics of any commercially available decking species. For contractors and homeowners willing to look beyond the established names, Massaranduba offers exceptional value.

Performance Profile

Massaranduba's Janka hardness of 3,190 lbf places it firmly between Cumaru (3,330) and Ipe (3,680) — harder than 99% of all commercially available wood species. Its density of 60–68 lb/ft³ is comparable to Cumaru and provides excellent natural resistance to decay, insects, and marine borers.

The species carries a Class A fire rating, matching Ipe and Cumaru. Natural durability ratings classify it as "very durable," with an expected exterior lifespan of 30–50+ years when properly installed.

Color and Appearance

Freshly milled Massaranduba displays a rich, deep reddish-brown color that's warmer and more consistently red than Ipe's olive-brown or Cumaru's variable gold-to-brown. The color is reminiscent of fine mahogany but with dramatically superior exterior performance.

Grain is typically fine and uniform with a natural luster that takes finish beautifully. Like all tropical hardwoods, unfinished Massaranduba will weather to silver-gray over time.

Working Properties

Massaranduba works similarly to Cumaru and Ipe: pre-drilling is mandatory, carbide tooling is required, and stainless steel fasteners are essential. The species has moderate silica content, which dulls blades somewhat faster than Ipe but slower than Cumaru.

One notable characteristic is Massaranduba's natural latex content. Freshly cut boards may exude a milky sap that can stain clothing and interfere with finish adhesion if not properly cleaned. Wipe fresh cuts with mineral spirits before finishing.

Pricing

Massaranduba typically costs 15–25% less than Ipe for equivalent grade and dimensions, placing it in the same price range as Cumaru. Given its performance metrics, this represents excellent value.

Availability

Massaranduba is less widely stocked than Ipe and Cumaru, which is its primary market limitation. Not all tropical hardwood suppliers carry it, and lead times may be longer for large orders. However, suppliers who do stock it report growing demand as contractors discover the species' exceptional combination of performance and value.

The Verdict

Massaranduba is arguably the most undervalued species in the tropical hardwood market. Its performance metrics rival Ipe, its color is distinctive and appealing, and its price point is significantly lower. For contractors looking to offer clients a premium product at a more accessible price, Massaranduba deserves serious consideration.
