What is the strongest wood in the US?
Of locally available woods, Black Ironwood is typically the strongest type of wood you can find in America. It's found in Florida and has a 3,660 lbf (16,280 N) Janka rating. Other strong North American woods include species of hickory, maples, oaks, walnuts, and beeches.
1. Australian Buloke – 5,060 IBF. An ironwood tree that is native to Australia, this wood comes from a species of tree occurring across most of Eastern and Southern Australia. Known as the hardest wood in the world, this particular type has a Janka hardness of 5,060 lbf.
As you can see in the accompanying graph, rock maple is the hardest of these four hardwoods - about 15% harder than red oak, which ranks second. Black walnut ranks third in hardness - about 20% below red oak. Cherry is another 5% or so softer than walnut.
Lignum vitae is one of the heaviest, hardest woods in the world. By comparison, while wenge is still a rather hard and heavy wood, it's considerably lighter and softer than the lignum vitae—yet its modulus of elasticity (on average) is higher than that of lignum vitae.

BIRCH HARDWOOD
Birch is harder than Cedar, stable, and relatively easy to work with. Birch is less expensive than several types of hardwoods and is readily available.
When strength is paramount, grain direction may not be your only consideration. Some species of wood are naturally stronger than others. Chairmakers, for example, typically use maple, birch, and hickory for legs, rungs, and spindles.
Redwood – It's one of the lightest and most durable woods used for building. It's one of the many reasons why Redwood is such a popular building material. Heartwood redwood grades are the most durable.
Liangbing Hu holds pieces of super wood made by removing lignin from and compressing basswood. The super wood is as strong as steel yet lightweight, making it ideal for structural uses.
What is the longest lasting wood? Teak, oak, cedar, mahogany and cherry are some of the types of wood that can last for centuries.
What is the weakest wood?
It's common knowledge, but Balsa is indeed the softest and lightest of all commercial woods. Nothing else even comes close.
The densest of all woods is Allocasuarina luehmannii. Krugiodendron typically has a higher density, among many other woods that vary by sample. Various other hardwoods may also be called lignum vitae and should not be confused with it.

Cedar is among the densest wood species, which helps prevent cracking due to changes in moisture. Fir is very stable once its moisture content reaches equilibrium with the relative moisture of the surrounding air. At equilibrium, or when the wood is “seasoned”, fir will undergo very little shrinking or warping.
The main differences
Walnut is rated at a 1010 on the Janka Hardness Scale. European Oak is a 1360 on the same scale. This means that Oak is more durable than Walnut and will stand up better against constant use and daily wear and tear.
While very hard and durable, in reality, oak ranks as the fourth hardest of the North American hardwoods. Hickory, with a Janka Hardness rating of 1820, leads the pack, followed by maple and then ash.
Is Black Locust harder than oak? Black Locust wood is harder than White Oak. We measure hardness of wood with the Janka Hardness scale: the higher the number the tougher the wood. Black Locust wood's Janka hardness scale is 1,700 lbf (7,560 N) compared to White Oak Janka hardness scale of 1,360 (6,000 N).
Over 4,789 years old, the age of Methuselah was determined by the measurement of core samples taken in 1957. The storied bristlecone pines grow in isolated groves at and just below the tree line in mountainous regions of California, Nevada and Colorado.
Maple wood is harder than oak, but not as stable. Hardwood harvested from the outer wood of the trunk, or sapwood, is usually a light creamy white color, while hardwood harvested from the center of the tree, or heartwood, is a deeper shade of brown with a slight reddish hue.
The hardness of wood is indicated with the Janka scale. It was developed by Gabriel Janka to measure a wood's resistance to wear and denting. The Janka hardness rating for pine is 420, while the Janka hardness rating for poplar is 540, which means poplar is generally harder, but there are hard pines that rate higher.
Doug-Fir. Douglas-fir, popularly known as Doug-fir, is undoubtedly the best and most common structural lumber. It is most architects' and engineers' go-to lumber species and this is not just because of its remarkable dimensional stability. It is also among the strongest and most durable softwood lumbers.
Which is harder maple or poplar?
Soft maple holds the same hardness rating as cherry at 950 on the Janka Hardness Rating Scale, making it harder than African mahogany at 830, alder at 590 and poplar at 540.
Liangbing Hu holds pieces of super wood made by removing lignin from and compressing basswood. The super wood is as strong as steel yet lightweight, making it ideal for structural uses.
Lignum vitae, a hardwood native to the West Indies, has the finest-grain of any wood known and an ironlike density. A cubic foot of it, air-dried, weighs about 83 pounds-so heavy that it won't float.
Common red oak has a Janka hardness of 1220 lbf, meaning it takes 1220 pounds of force to drive the steel ball halfway into the wood. For reference, soft balsa wood requires only 67 lbf and the hardest wood in the world, Australian Buloke, has a Janka hardness of 5060 lbf.
The densest of all woods is Allocasuarina luehmannii. Krugiodendron typically has a higher density, among many other woods that vary by sample. Various other hardwoods may also be called lignum vitae and should not be confused with it.
