Do you want to get the hardest wood for your construction needs? Then, you’d need to answer this question first: What is the strongest wood? To do so, you can trust on Janka Hardness Test - a wood hardness rating standard. This kind of test is created by Gabriel Janka to measure the force need to embed a steel ball into the surface of the wood. It has been used on various woods to determine the most suitable species for flooring and is measured by pounds-force (lbf).
The hardest woods are those who are more prone to resist wear and dent. So if you need the most durable material, whether it’s for your house or a company building, you might want to check out this top 10 strongest wood.
10. African Pearwood or Moabi (3,680 lbf)
African Pearwood or Moabi is sometimes pinkish brown or dark red-brown in color. The color is an indication of its age. The darker it is, the older the wood. When cut, you’ll see grain patterns in it like that of a beeswing, mottled, and pommele. The grain can be fine and even, but will range from wavy to straight. The wood does not produce any kind of odor.
With 3,680 lbf, it is durable and resistant to insects. However, you can easily work with it using machine or hand tools. It also glues, turns, and finishes quite well and responds better to steam bending. Just remember that African Pearwood is high in silica content; thus its cutting edges will dull with tool steel. Also, it’s known to cause severe reactions like nose and eye irritation if handled without protection.
African Pearwood is usually used in making veneer, fine furniture, turned objects, cabinets, and other specialty products.
9. Brazilian Walnut (3,684 lbf)
Also known as Ipe or Lapacho, the Brazilian Walnut is sometimes reddish brown in color, sometimes yellowish olive, and sometimes brackish brown. Thus, it can be difficult to distinguish with other woods like Cumaru. However, Brazilian Walnut tends to be a little darker and it lacks the vanilla scent common in Cumaru. Its texture ranges from medium to fine and its grain can vary from interlocked to straight.
With 3,684 lbf, it’s very durable and can resist insects and weather changes. In fact, it’s said to have been used as the boardwalk in Coney Island, New York and has lasted for 25 years. Working with Brazilian Walnut can be difficult, though. It is dense and hard so it has high cutting resistance. Its yellow deposits can get in the way of polishing, too. Moreover, it’s said to cause eye, respiratory, and skin irritation if handled without protection.
Brazilian Walnut is usually used in decking, veneer, exterior lumber, flooring, etc.
8. Brazilian Ebony (3,692 lbf)
Brazilian Ebony is a heavy wood that comes with a range of figures and colors. It can be streaked or marble-like. It can be olive brown or blackish with light markings.

Its texture is often fine and uniform and its grain is usually straight but can sometimes be irregular.
Since this wood is hard, it can be resistant to sanding and cutting. Also, working with hand tools can be difficult. It does hold nails well once they’re applied and be polished to a good finish with lesser difficulty.
Brazilian Ebony is good for planking and decking. You can also use it for railing, trim works, and fittings.

Though one of the lesser-known woods, there’s no doubt that Brazilian Olivewood can compete with the others when it comes to durability. It comes with dark brown or yellow-brown color. Its grain is straight and its texture is usually fine.
Brazilian Olivewood is durable to any kinds of fungi. The presence of demarcated sapwood might be one of the reasons for its durability. It can blunt hand tools, so slicing is not recommended. You might also have trouble when it comes to interlocked grain. Nailing is good and gluing can be done for the interior.
You can use this wood for flooring, paneling, high-class furniture, ship building, bridges, joinery, and more.
6. Snakewood (3,800 lbf)

4. Pockholz (4,500 lbf)
Pockholz is also known as lignum vitae and guayacan. As one of the hardest and most durable wood, you can hardly find this greenish wood in local construction shops.
