Acacia wood is a hardwood with a Janka hardness rating between 1170 and 2345, similar to red oak. Factors like species, age, growing conditions, and cutting season influence its hardness. Although it’s denser and more challenging to work with, its hardness grants it excellent durability.
But that’s a quick snapshot.
In this article I’ll deeply talk about how hard is Acacia wood, is Acacia wood hardwood or softwood by considering its characteristics.
Furthermore, I’ll discuss the uses of Acacia wood in terms of its hardness and how strong it is.
Finally, I’ll answer frequently asked questions as well.
So, just keep reading!
First of all, let’s get a quick look at what is acacia wood.
What is Acacia Wood?
Acacia wood is a type of hardwood derived from the Acacia genus of trees and shrubs, which consists of more than a thousand different species.
These trees are native to various parts of the world, including Australia, Africa, North America, and Asia, each with unique climates that play a role in determining the properties of the acacia wood they produce.
Appearance of Acacia Wood
Acacia trees are notable for their attractive, exotic appearance.
They are often characterized by their gnarly branches and delicate, fern-like leaves.
Depending on the species, the acacia tree can produce blossoms that vary in color from bright yellow to subtle creams, enhancing their natural beauty.
The wood from acacia trees is known for its strength, durability, and unique grain patterns.
It displays a broad range of colors, from a light, golden hue to a rich, dark brown, often accompanied by an attractive natural sheen.
Sustainability and Acacia Wood
With the growing awareness around the importance of sustainability, acacia wood has become increasingly popular.
Many species of acacia trees grow quickly, maturing within five to seven years, making them a more sustainable choice compared to other hardwood trees that take decades to reach full maturity.
In summary, acacia wood is a versatile, attractive, and sustainable option that serves a myriad of uses, particularly in furniture making.
Its inherent durability, coupled with its unique aesthetics and sustainable growth, make it a popular choice for homeowners and designers alike.
It’s an excellent option if you’re seeking to combine style, function, and sustainability in your space.
Now you have a proper understanding of acacia wood. So, let’s start the discussion about its hardness.
Is Acacia Wood Hardwood?
Yes, Acacia wood is hardwood. It is incredibly strong and durable with a higher hardness rating of 2,300 lbf (10,230 N).
Acacia wood is harder than most other woods. When we look at the structural properties of Acacia wood, it has a less porous structure than most other woods.
This is why Acacia has high density as well as high hardness value. Because of having a less porous structure, the number of fiber per unit area is high and that increases its density.
Because of being hardwood with outstanding hardness, Acacia is used to making cutting boards that can easily withstand knife edges.
The straight or wavy wood grain of Acacia wood increases its hardness and strength.
So, let’s have a look at the hardness scale of Acacia wood according to the Janka hardness value.
Tip: Janka hardness test is the best measure measurement to identify the hardness of a particular wood. it measures the resistance of wood to dent and wear.

Acacia vs Birch Hardness
If you’re contemplating between acacia and birch for your next furniture purchase or woodwork project, the relative hardness of these two types of wood can be a significant factor.
Let’s explore this topic further.
Hardness of Acacia Wood
As we’ve discussed earlier, acacia wood’s hardness is quite remarkable. It typically ranges from 1170 to 2345 on the Janka hardness scale, making it a considerably hard wood.
This hardness contributes to its durability and resistance to scratches and dents, making it a great choice for high-traffic areas and heavy-duty applications, such as flooring or outdoor furniture.
Hardness of Birch Wood
In contrast, birch wood is generally softer than acacia. The Janka hardness scale rates birch at around 1260, which is at the lower end of the range for acacia.
However, it is still considered a hardwood and is actually slightly harder than renowned hardwoods like red oak.
Birch wood’s moderate hardness makes it quite workable, and it can be shaped into detailed and intricate designs with relative ease.
Comparing Acacia and Birch Hardness
While both acacia and birch are considered hardwoods, acacia is generally harder than birch.
This means acacia wood furniture or flooring will likely stand up better to heavy use and potential damage over time.
However, the relative softness of birch, while still being durable, makes it a bit easier to work with.
As with any decision on materials, your choice between acacia and birch wood should be influenced by more than just hardness.
Consider also factors like aesthetic preference, the specific demands of your project, cost, and the environmental impacts associated with each type of wood.
Remember, the most suitable wood for your needs depends on a balance of these factors rather than any single characteristic.
Each wood type, whether it be acacia or birch, carries its unique blend of advantages.
Acacia’s superior hardness, coupled with its beautiful grain patterns, makes it an attractive choice for enduring pieces.
On the other hand, birch, with its moderate hardness and exceptional workability, offers a high degree of versatility for creative woodworking.
In the end, it’s all about what best suits your needs and preferences.
Acacia Vs Birch Comparison Table
