Because of its beautiful grain, Acacia wood is popular for decorative purposes as well. When I was first started to work with this awesome wood, I was always wondered, How hard is Acacia wood?

I looked into it and here’s what I discovered:

Acacia wood has a hardness rating of 2,300 lbf (10,230 N). Acacia wood is harder than many hardwoods such as Oak, Hickory, Maple, Beech, and many more. It is incredibly strong and durable. Because of being hard, Acacia wood is resistant to dents, scratches, and fungus attacks. Acacia wood is one of the best and hardwood for any woodworking project.

But that’s a quick snapshot.

From this article we’re going to deeply talk about how hard is Acacia wood, is Acacia wood hardwood or softwood by considering its characteristics. Furthermore, we are going to discuss the uses of Acacia wood in terms of its hardness and how strong it is. Finally, we are going to answer frequently asked questions about the hardness of Acacia wood.

So, just keep reading!

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 wood has a hardness rating of 2,300 lbf (10,230 N). hereby I have listed the hardness of popular woods according to the Janka hardness test to get an idea about how hard Acacia wood is.

As you can see Acacia wood is one of the hardest woods. Acacia wood is 23% harder than Hickory, 55% harder than white Oak. The density of Acacia wood is 760 kgm-3 which is also pretty much higher than any softwood and most of the hardwoods as well.

So, let’s have a look at the characteristics of Acacia wood to get a clear idea about its hardness and strength.

Acacia Wood Characteristics

Acacia wood has a medium to dark brown color range which turns into a reddish tone over time. Woodgrain is straight or wavy.

Because of being hardwood, Acacia wood is harder and denser than many other wood types.

Acacia wood has very little porous structure and this makes it a bit difficult to take stain and paint well. When we apply paint coatings, the pigments will penetrate through the pores of the wood to absorb the paint. But in Acacia wood, because of has a less porous structure, it is so much hard to absorb the coatings well. Therefore, in terms of finishing, Acacia wood is a difficult wood to paint or stain.

Surprisingly, Acacia wood is incredibly lightweight. Most of the time, woods with high density and less porosity are heavy. But Acacia wood is lightweight, hard, and strong wood. Therefore, Acacias wood has high workability. Sawing, brushing, gluing, and is easy, but knockouts are needed for nailing and screwing because of being a hardwood.

The great qualities of Acacia wood are,

  • Hardwood
  • Lightweight
  • High durability
  • Rot-resistant
  • Beautiful wood grain
  • Scratch-resistant
  • High workability
  • Low maintenance
  • High sustainability

 As a summary, the main characteristics of Acacia wood can be displayed as follows.

ColorMedium to dark brown color
Density760 kgm-3
Hardness2,300 lbf (10,230 N)
Stiffness1,476 ksi
ApplicationsIndoor and outdoor furniture, flooring, constructions

So, let’s have a look at the uses of Acacia wood to get an idea about the importance of being harder than most other woods.

Uses of Acacia Hardwood
