Mahogany Wood Characteristics: Grain, Hardness & Workability

Mahogany is a reddish-brown tropical hardwood of medium density, about 590 kg/m3 for Honduran and 545 kg/m3 for African, that machines, glues and finishes easily and darkens as it ages. Its one real quirk is variable grain: straight in some boards, interlocked and tear-out prone in others. This guide covers its look, a working-properties table, the species sold as mahogany, common uses and CITES status.

What Are the Key Characteristics of Mahogany Wood?

Mahogany is a medium-hard, medium-weight, stable hardwood with a warm color and a fine, even texture. Those traits, rather than extreme hardness or strength, are why it became the default wood for fine furniture, cabinetry, instruments and boats. The figures below are for Honduran mahogany (Swietenia macrophylla) from the Wood Database, the true mahogany most woodworkers mean:

• Color: pale pinkish brown to darker reddish brown, and it darkens with age.
• Grain and texture: straight, interlocked, irregular or wavy grain with a medium, uniform texture and moderate natural luster.
• Hardness: 900 lbf on the Janka scale, which is medium.
• Weight: an average dried weight of 36.8 lb/ft3 (590 kg/m3), with a specific gravity of 0.52 to 0.59.
• Working: typically very easy to work with hand and machine tools, except in figured or interlocked sections.
• Odor: no characteristic odor.

Mahogany Appearance: Color, Grain and Chatoyance

Fresh-cut mahogany tends to look pale pink to light brown. The deep reddish-brown people associate with antique furniture develops over years of light exposure, so a new board will not match an old one until it ages or is stained. That is also why matching repairs on older pieces is harder than it looks.

Grain is where mahogany varies most. The Wood Database lists it as straight, interlocked, irregular or wavy, and describes the texture as medium and uniform with moderate luster. Interlocked grain is the usual source of ribbon stripe figure and the shimmering, light-catching look called chatoyance, which the Wood Database notes for both Cuban and African mahogany. It is also the same feature that makes some boards tear out when planed. Our guide to mahogany wood grain, ribbon figure and chatoyancy shows what each pattern looks like, and is mahogany a dark wood explains how the color changes over time.

The endgrain is diffuse porous with large, few vessels, which means the surface has visible open pores. They give flat boards their fine dashed lines, and they matter for finishing, as the working section below explains.

Mahogany Properties Compared: Honduran, Cuban and African

Most buyers never see a side-by-side of the three woods sold as mahogany, and the differences are small but real. The table puts the published figures together so you can compare them directly.

Property	Honduran (Swietenia macrophylla)	Cuban (Swietenia mahogani)	African (Khaya spp.)
Janka hardness	900 lbf	930 lbf	850 lbf
Average dried weight	36.8 lb/ft3 (590 kg/m3)	37 lb/ft3 (600 kg/m3)	33.9 lb/ft3 (545 kg/m3)
Specific gravity	0.52 to 0.59	0.53 basic, 0.60 at 12% MC	0.46 to 0.54 (12% MC)
Bending strength (MOR)	11,710 psi	not listed	11,730 psi
Stiffness (MOE)	1,458,000 psi	not listed	1,410,000 psi
Crushing strength	6,760 psi	not listed	6,570 psi
Shrinkage, radial / tangential	2.9% / 4.3%	not listed	3.4% / 5.7%
Tangential-to-radial ratio	1.5	not listed	about 1.7 (calculated)
Rot resistance (heartwood)	Moderately to very durable	Moderately to very durable	Moderately durable

What the numbers say in practice:

• Honduran and Cuban are the denser pair. At 900 and 930 lbf they are close to each other, while African mahogany is lighter and a little softer at 850 lbf. All three are medium-hard, so mahogany dents more easily than the oaks and maples used for flooring or workbenches.
• Strength is nearly identical. Honduran and African mahogany differ by only about 20 psi in bending strength (11,710 versus 11,730), so the choice between them is about weight, grain and cost rather than structural capacity.
• African mahogany moves more. Its tangential shrinkage is 5.7% against 4.3% for Honduran, and its tangential-to-radial ratio works out to about 1.7 against 1.5. As an illustration, a 12 inch wide flatsawn board that lost the full tangential percentage would shrink about 0.52 inch in Honduran and about 0.68 inch in African mahogany. In real furniture the swing is much smaller than the full figure, but the gap is why quartersawn stock and wide-panel construction deserve extra care with African mahogany.

Rot resistance is covered in detail on our mahogany wood durability page. The short version is that heartwood is rated moderately to very durable for Honduran and Cuban mahogany depending on tree density and growing conditions, and moderately durable for African.

How Mahogany Works: Machining, Gluing and Finishing

The Wood Database describes Honduran mahogany as typically very easy to work with both hand and machine tools, and it sands easily and finishes well. African mahogany is described the same way with one caveat: tear-out can be a problem where the grain is interlocked. It also glues, turns and finishes well.

That matches what most people find at the bench: straight-grained mahogany cuts almost like a soft hardwood, while a board with ribbon figure can plane beautifully in one direction and tear in the other. A few habits help:

• Read the grain before you plane. Look at the edge of the board and plane in the direction the grain rises toward the surface, and take light passes with a sharp, finely set blade.
• Scrape instead of fighting it. A card scraper shaves interlocked sections where a plane would lift them, and it leaves a smoother surface than sandpaper alone.
• Fill the pores for a glass-smooth finish. Because the pores are large and open, a clear gloss finish over bare mahogany shows them. Many woodworkers use a grain filler first; for satin or oil finishes you can often skip it.
• Mind the metal. The Wood Database notes African mahogany can stain in damp conditions around iron fasteners, so use stainless or brass hardware outdoors or in humid spaces.
• Pick a finish for the job. Our mahogany finish comparison covers cost per 100 square feet for seven options.

Mahogany dust safety

The Wood Database lists mahogany as a sensitizer, with reported eye, skin and respiratory irritation and rare severe reactions. Sanding and scraping both produce fine dust, so use dust collection, wear a respirator when sanding, and wash skin that contacts the dust. This is a precaution, not a reason to avoid the wood.

Which Woods Are Sold as Mahogany?

The name covers three genuinely related woods and one that is not related at all. Knowing which you are buying matters because price, weight and availability differ.

• Honduran mahogany (Swietenia macrophylla) grows from southern Mexico through central South America and in plantations. Trees reach 150 to 200 feet with trunks 3 to 6 feet across. It is the benchmark for “genuine” mahogany.
• Cuban mahogany (Swietenia mahogani) is the classic antique furniture wood. It is a touch harder and denser than Honduran, and it is rarely sold as new lumber today.
• African mahogany (Khaya spp.), mainly K. anthotheca and K. ivorensis, comes from tropical Africa. It is lighter, a little softer, has high chatoyance and is usually cheaper than Honduran mahogany.
• Philippine mahogany is not mahogany. The Wood Database says the term covers mostly commercial lumber in the Shorea genus and that it has no relation to true mahogany in the Swietenia and Khaya genera. It is also sold as meranti, and as lauan when made into plywood.

If you are trying to tell them apart in a lumberyard, our guides to mahogany wood types, what kind of wood mahogany is and how to identify mahogany cover the differences. For African mahogany against its lookalike, see African mahogany vs sapele and mahogany vs sapele.

What Is Mahogany Used For?

The Wood Database lists furniture, cabinetry, veneer, musical instruments and boatbuilding as the common uses of Honduran and Cuban mahogany. For African mahogany it lists veneer, plywood, furniture, boatbuilding, interior trim and turned items.

Each use maps to a characteristic covered above:

• Furniture and cabinetry: easy machining, good gluing and a warm color that deepens with age. See mahogany vs cherry for the closest domestic alternative.
• Instruments: medium density and low weight for its strength. We cover tone and weight in whether mahogany is good for guitars.
• Boats: decay resistance and stability, though finish and fasteners still matter. For marine plywood, see okoume vs mahogany.
• Trim and paneling: uniform texture takes stain and clear finishes evenly. See mahogany wall paneling for costs.
• Outdoor furniture: workable with a good finish but not maintenance-free; teak vs mahogany compares the two.

Availability, Price and CITES Status

According to the Wood Database, Honduran mahogany is mid-range in price for an imported hardwood and costs more than African mahogany. Availability is tied to its conservation status: Honduran mahogany and Cuban mahogany are both listed in CITES Appendix II, as are all Khaya species, and the Wood Database reports the IUCN Red List classes Honduran mahogany as endangered (a population decline of more than 60%), Cuban mahogany as endangered (more than 50%), and the main African species as vulnerable (more than 20%).

Appendix II is not a ban. It means international trade is regulated and needs permits, which is why reputable dealers can supply legally sourced lumber and why unusually cheap “genuine” mahogany deserves suspicion. Ask for the species name and country of origin when you buy. Our where to buy mahogany wood guide covers sellers, and mahogany tree facts covers the tree and its listing.

Common Mahogany Myths, Corrected

• “Mahogany is very hard.” It is medium. Honduran sits at 900 lbf, Cuban at 930 and African at 850, so it dents more easily than hard maple or white oak. Its reputation comes from stability and finish quality, not hardness.
• “Mahogany never rots.” Heartwood is rated moderately to very durable for Honduran and Cuban mahogany and moderately durable for African, depending on the tree. The Wood Database also notes it resists termites but is vulnerable to other insects.
• “All mahogany is the same wood.” Honduran, Cuban and African mahogany differ in density, shrinkage and price, and Philippine mahogany is a different genus altogether.
• “Mahogany is always dark red.” New heartwood runs from pale pinkish brown to reddish brown, and the deep color comes with age or stain.

Frequently Asked Questions

What are the main characteristics of mahogany wood?

Mahogany is a medium-hard, medium-weight tropical hardwood that ranges from pale pinkish brown to reddish brown and darkens with age. Honduran mahogany has a Janka hardness of 900 lbf and an average dried weight of 590 kg/m3. The grain can be straight, interlocked or wavy, and the wood machines, glues and finishes easily.

What is the Janka hardness of mahogany?

Honduran mahogany measures 900 lbf, Cuban mahogany 930 lbf and African mahogany 850 lbf, according to the Wood Database. That places all three in the medium range, softer than most oaks and maples but harder than many softwoods.

Is mahogany hard to work with?

No. The Wood Database calls Honduran mahogany typically very easy to work with hand and machine tools, and it sands easily and finishes well. The exception is figured or interlocked grain, which can tear out when planed, so use sharp blades, light passes or a card scraper.

Is Philippine mahogany real mahogany?

No. Philippine mahogany is a trade name for lumber from the Shorea genus, also sold as meranti or lauan plywood. It is unrelated to true mahogany in the Swietenia and Khaya genera, and its color and working properties vary by subtype.

Does mahogany change color over time?

Yes. Fresh heartwood is pale pinkish brown to reddish brown, and the Wood Database notes the color darkens with age. A finished piece will keep deepening for years, so a new repair board will look lighter than the surrounding old wood until it catches up.

Is mahogany dust harmful?

It can irritate. The Wood Database lists mahogany as a sensitizer with reported eye, skin and respiratory irritation, and rare severe reactions. Use dust collection, wear a respirator when sanding and wash skin that contacts the dust.

Conclusion

Mahogany earns its place through balance rather than extremes: medium hardness, medium weight, good stability, easy machining and a color that improves with age. Check which species you are buying, plan for tear-out in interlocked boards, and protect your lungs when sanding. For the next questions in the decision, read our guides to durability and finishing.
