Is Mahogany a Strong Wood? Here Are The Facts

One of the most popular kinds of wood for furniture and woodworking projects is mahogany. This type of wood is known for its beauty and versatility but is mahogany a strong wood?

Let’s find out why mahogany is a favorite among woodworkers, furniture makers, and hobbyists. Also, let’s learn about the background of mahogany and how it compares with other popular woods like oak and pine.

Quick Answer

Mahogany is solid wood. It has high compressive and bending strengths compared to other types of wood. Many woodworkers, furniture makers, hobbyists, and carpenters choose mahogany over other woods because it’s durable and thus perfect for many applications.

Because mahogany is so strong, this wood is used mainly in building furniture, watercraft, flooring, musical instruments, and much more.

How Strong is This Type of Wood?

Mahogany is strong, but how strong is this wood? Strength is measured by the following factors: compressive strength, density, hardness, bending strength, and stiffness.

Compressive Strength of Mahogany – 6,460 psi

Compressive strength is measured in two ways: compressive strength parallel to the grain and compressive stress perpendicular to the grain.

Compressive strength parallel to the grain is the wood’s maximum crushing strength. This is the highest amount of stress it can sustain by compressing it parallel to the grain. The length ratio of the specimen is less than 11.

The compressive stress perpendicular to the wood’s grain is the maximum stress that a wood specimen can take when it’s crushed perpendicularly to its grain. This is also called the proportional value of the wood, and there’s no defined stress value for it.

An average sample of mahogany wood has a moderate compressive strength of 6,460 psi compared to other commercial wood species like hickory with 9,210 psi and hard maple with 7,830 psi.

Density of Mahogany – 0.42 kg/m3

Wood density is the amount of wood found in a unit per volume of a wooden sample. Basic wood density refers to the ratio of dry weight as well as the green volume of the sample. When a specimen has higher wood content per volume, this means that wood has a higher density.

Density varies from one type of wood to another depending on some factors: the wood’s growing environment, the tree species, and the tree area to be calculated. When it comes to the tree parts, the branches have less wood density than the tree trunk.

Trees that grow faster have lower densities than those that grow slowly. Mahogany is a slow-growing tree that matures at 25 years. This is why mahogany is one of the densest woods.

Hardness of Mahogany – 830 pounds

Wood hardness is the wood’s resistance to wear and denting. Janka test describes wood hardness as the force needed to drive an 11.28mm steel ball through a wood that’s half the diameter of the steel ball.

Mahogany is a hardwood with a Janka rating of 800 to 900 pounds per foot. Compared to other commercial woods, mahogany has an average hardness rating. Hickory has 1,820 pounds per foot, white oak has 1,360 pounds per foot, cherry has 995 pounds per foot, and Southern yellow pine has 870 pounds per foot.

Bending strength of Mahogany – 10,700 psi

Also called modulus of rupture, the bending strength is the load that a piece of wood can withstand applied perpendicular to its grain. The MOR can be used to describe wood’s overall strength. This is not the wood’s overall strength compared to the modulus of elasticity that describes a wood specimen’s deflection.

Mahogany has a moderate modulus of rupture at 10,700 psi. Some of the woods with the highest MOR are African Blackwood, Verawood, Brazilwood, and Rosewood.

Stiffness strength of Mahogany – 1.40

The wood’s modulus of elasticity is the measurement of its stiffness. It is one of the factors that determine a wood’s strength. MOE is described as the ratio of stress placed on the wood specimen compared to the deformation that it produces along the specimen’s length. Mahogany wood is slightly elastic at 1.40.
