What is the densest wood?
Lignum vitae
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lbs/ft3 or ~1260 kg/m3); it will easily sink in water.
Are ironwood trees rare?
The Ironwood or Tree of Life (Lignum vitea) is a rare, hard to find species that is native to the Florida Keys. It is rarely seen any more in the wild due to over harvesting for the dense oily wood that is very popular for wood working.
How strong is Ironwood?
22.5 thousand Newtons
While ironwood’s hardness is 22.5 thousand Newtons, aluminium is only 15 thousand Newtons hard.
What makes Ironwood so heavy?
So, as to what makes it so heavy, the basic answer is cellulose density. Cellulose, the stuff Ma Nature makes her wood with, is heavier than water. The actual wood cells are filled with water and then, after drying, air. The balance of air/water and cellulose determines the weight of the wood.
What are high density woods?
HDF is referred to as hardboard, a high density fiberboard (HDF) for flooring is a type of engineered wood product. It’s made from wood fiber extracted from chips and pulped wood waste. HDF for flooring is similar but much harder and denser than particle board or medium density fiberboard (MDF) for flooring.
What is Ironwood good for?
It’s durable and holds up well to pressure and strain. Ironwood has been put to use as sleigh runners, tool handles and levers (hence, “leverwood”). The “hornbeam” part of the common name, hop hornbeam, also comes from its strength-under-pressure qualities.
What is so special about Ironwood?
The only species in the genus Olneya, ironwood is notable for its slow growth rates and extremely dense wood. Its wood even sinks in water. While scientists consider ironwood to be the “old growth” tree of the desert, standard tree-ring dating of its wood is difficult.
Is Ironwood the hardest wood?

How big is the density of Ironwood?
Ironwood is a common name for many woods or plants that have a reputation for hardness, or specifically a wood density that is over 1000 kg/m 3 and sinks in water.
Where are ironwood trees found in the world?
In East Kalimantan this tree (Eusideroxylon zwageri, Fam. Lauraceae) is rather common within lowland dipterocarp forest. Ironwood trees can form a distinctive, monodominant forest like in Sumatra or as scattered individuals and small stands as found in East Kalimantan.
What was the purpose of eastern Ironwood wood?
Its wood is very durable and used for making a variety of modern tools. Interestingly, its extremely high density and resistance to compression makes an excellent material for the construction of wooden longbows, which were an important weapon historically.
