Mahogany wood is a popular choice for furniture-making due to its rich, reddish-brown color.
There are several types of mahogany wood, each with its own unique characteristics.
African Mahogany, also known as Khaya senegalensis, is a fast-growing tree native to tropical Africa.
It's often used for furniture, flooring, and wood carvings due to its durability and resistance to rot.
Types of Mahogany Wood
Genuine mahogany comes from the genus Swietenia, which includes three types of trees: Swietenia macrophylla, Swietenia humilis, and Swietenia mahogani. These trees are the only true mahogany species.
Each type of genuine mahogany has its own unique characteristics and is classified as vulnerable to extinction or endangered due to illegal harvesting.
Swietenia mahogani, also known as Cuban mahogany, is one of the most revered fine furniture woods in the world, prized for its beauty and durability. It's found in southern Florida and the Caribbean, and its heartwood ranges from pale pinkish-brown to dark reddish-brown.

The other two genuine mahogany species, Swietenia macrophylla and Swietenia humilis, are also highly valued for their wood, but are less common than Swietenia mahogani.
Here's a list of the three genuine mahogany species, along with some of their key characteristics:
- Swietenia macrophylla (Honduran mahogany, West Indian mahogany, big-leaf mahogany)
- Swietenia humilis (Mexican mahogany, Pacific Coast mahogany, Honduras mahogany)
- Swietenia mahogani (Cuban mahogany, American mahogany, small-leaved mahogany, West Indian mahogany)
It's worth noting that African mahogany, which comes from the khaya genus, is often marketed as a more affordable alternative to genuine mahogany, but it's not actually a member of the Swietenia genus.
Utile
Utile is a type of mahogany wood found in west and central Africa. It's also known as sipo or sipo mahogany.
The wood has an interlocking grain similar to other mahogany species, with a close match to genuine mahogany. This makes it a great option for roof systems, roof lanterns, and custom skylights.
Utile is extremely dense, with an average dry weight of 40 lbs/ft3 (635 kg/m3). This density makes it suitable for use in roof systems.
The heartwood of utile tends towards a reddish brown color, while the sapwood is a paler yellow. This color variation can add a beautiful aesthetic touch to any project.
Utile has a Janka hardness of 1,180 lbf (5,260 N), which is similar in strength and stiffness to other mahogany species. This means it can withstand heavy loads and stresses.
In terms of shrinkage, utile has a radial shrinkage of 4.9%, tangential shrinkage of 6.9%, and volumetric shrinkage of 11.8%. This is a relatively high shrinkage rate, so it's essential to consider this when designing projects that involve utile wood.
Utile's crushing strength is 8,280 lbf/in2 (57.1 MPa), which is impressive for a wood species. This makes it an excellent choice for load-bearing applications.

Sapele
Sapele is a moderately priced substitute for traditional Genuine Mahogany.
Sapele lumber is indigenous to several countries in Africa, with most of it imported from the Congo.
The color of Sapele is a dark brownish red and can sometimes move into a purplish red hue.
Sapele has several variations, including flat sawn (cathedral) and quarter sawn (straight) grain.
J. Gibson McIlvain separates their Sapele according to these grain patterns.
Occasionally, they get in a shipment with several highly figured Pomelle boards.

Santos
Santos mahogany is a reliable wood type for flooring, heavy construction, and furniture due to its Janka hardness of 2,400 lbf.
It's commonly found in South and Central America, as well as southern Mexico, and can grow to be quite large, ranging from 65 to 100 feet in height.
The trunk size of a mature Santos mahogany tree is usually around 2-3 feet in diameter.
This wood type has a good variety of colors, ranging from light golden brown to darker purplish-red or burgundy.
As Santos mahogany ages, the wood turns more purple or dark red.
Compared to other exotic hardwoods like Ipe, Santos mahogany is actually significantly more affordable.
Its price falls in the mid-range, making it a great option for those looking for a reliable and affordable wood type.

Cuban
Cuban mahogany, also known as West Indian mahogany or Caribbean mahogany, is one of the most revered fine furniture woods in the world. It's been used extensively throughout history to make cabinets in the U.S. and Europe.
This wood is found in southern Florida and the Caribbean, and the heartwood ranges from pale pinkish-brown to dark reddish brown, getting darker with age and density. The older and denser the wood, the darker the color gets.
Cuban mahogany exhibits an optical phenomenon known as chatoyancy, which is a pretty unique feature. It also has really easy workability and strong stability, making it perfect for furniture manufacturing.
The Janka hardness of Cuban mahogany is 930 lbf, which is just right - it's pliant but durable. This makes it a great choice for furniture making, but be aware that very small quantities are currently available, so it's hard to get.
Here are some key characteristics of Cuban mahogany:
- Heartwood color: pale pinkish-brown to dark reddish brown
- Janka hardness: 930 lbf
- Workability: easy
- Stability: strong
- Grain: even and straight
African
African mahogany is a type of mahogany wood that originates from west tropical Africa. It's commonly referred to as khaya anthotheca, and is often used as a substitute for genuine mahogany due to its similar color and chatoyancy effect.
The African mahogany tree can grow up to 130 feet in height, with trunk diameters ranging from 3-5 feet. This wood has a Janka hardness rating of 1,070 lbf, making it perfect for fine furniture.
African mahogany has a medium to coarse texture, which needs to be treated properly to feel smooth. The grain pattern can be interlocked, which can increase the chances of tear-out.
African mahogany is found in various sizes and types, including veneer and plywood. Prices depend on the quality and import costs of the hardwood.
Here are some key characteristics of African mahogany:
African mahogany is used for various applications, including furniture, high-end musical instruments, architectural millwork, and window & door manufacturing. It's a popular choice due to its durability and attractive grain pattern.
African mahogany is sourced from various countries in Africa, including Ghana and Cameroon. Wood from this region is consistent in grade, color, and texture, and carries a very lustrous grain appearance.
In terms of durability, African mahogany has a high Janka hardness rating, making it resistant to wear and tear. It's also resistant to decay and insect damage, making it a great choice for outdoor applications.
Overall, African mahogany is a versatile and attractive type of mahogany wood that's perfect for various applications. Its durability, attractive grain pattern, and consistent quality make it a popular choice among woodworkers and manufacturers.
New World
The New World wood that we know as mahogany has a rich history. The first record of the word "mahogany" in print was in 1671.
It was initially thought to be a type of cedar, but was later classified as Cedrela Mahagoni in 1759.
Until the 19th century, people believed that all mahogany was the same, with variations only caused by climate and soil.
Mountain
Mountain mahogany is a dense wood that's often used as firewood due to its ability to burn evenly and at a high temperature.
The Janka hardness rating of mountain mahogany is 3,200 lbf, making it one of the densest woods you can get, but also very hard to work with.
Mountain mahogany is commonly found in northern Mexico and the western U.S., where it can grow up to 20 feet tall.
Its reddish-brown heartwood and pink or yellow sapwood give it a unique color that darkens with age, making it a beautiful choice for furniture and floors.
A 5-pound piece of mountain mahogany can cost around $10, which is a bit pricey due to its limited availability and difficulty to transport.
Mountain mahogany trees can grow up to 200 feet tall, with trunk diameters ranging from 3-6 feet in some cases.

Hardwoods are often denser and more durable than softwoods. Honduran mahogany, for example, has a Janka rating of 800, which is higher than some other types of wood, like eastern white pine and Douglas fir.
But, surprisingly, Honduran mahogany's Janka rating is lower than many other commonly-used woods, like cherry and white oak. Here's a comparison of some Janka ratings:
Origin and Collection
Mahogany wood often comes from Swietenia macrophylla trees, which are native to South America and Mexico.
These trees can grow up to 200 feet tall, with trunks that are 6 feet in diameter.
The average size of Swietenia macrophylla is closer to 130 feet tall, but it still takes decades for them to reach these heights.
Old growth Swietenia macrophylla is most at-risk for illegal harvest.
Additional sources of genuine mahogany are Swietenia humilis and Swietenia mahogani.
Swietenia humilis grows along the Pacific Coast of Central America, while Swietenia mahogani grows from the southern tip of Florida through the West Indies.
Mahogany Wood History
Mahogany trees have been around for a long time, but it wasn't until the era of colonization that they became widely known to the rest of the world.
Mahogany trees are indigenous to the Americas and are members of the genus swietenia.
There are only 3 swietenia species that are classified as being "genuine swietenia mahogany", while the rest are classified as "true mahogany", mostly khaya species.
These khaya species are the African genera of mahogany trees.
Genuine Mahogany Wood
Genuine Mahogany Wood is a highly prized material for woodworking projects. It's also known as Honduran Mahogany, and it's considered the real deal.
Genuine Mahogany has a rich, deep color that can range from paler browns with reddish notes to deep, reddish browns. This color tends to darken with age.
The wood has a Janka Hardness of 900 lbf (4,020 N), making it a durable choice for furniture making and other woodworking projects. Its Crushing Strength is also impressive, at 6,760 lbf/in2 (46.6 MPa).
