Xanthostemon verdugonianus, commonly known as mangkono or Philippine ironwood, is a species of plant in the family Myrtaceae. [2] It is endemic to the islands of the Visayas, Palawan, and northeastern Mindanao. It is valued for its extremely durable and heavy timber. It is threatened by habitat loss.
Acacia estrophiolata, commonly known as ironwood, [1] southern ironwood, [2] desert ironwood [3] ... The wood is very hard and it is good for making posts for fences. [6]
Ironwood is a common name for many woods that have a reputation for hardness, or specifically a wood density that is denser than water (approximately 1000 kg/m 3, or 62 pounds per cubic foot), although usage of the name ironwood in English may or may not indicate a tree that yields such heavy wood.
Seri ironwood carving. Mexican ironwood carving is a Mexican tradition of carving the wood of the Olneya tesota tree, a Sonora Desert tree commonly called ironwood (palo fierro in Spanish). Olneya tesota is a slow growing important shade tree in northwest Mexico and the southwest U.S. The wood it produces is very dense and sinks in water.
Olneya ironwood is very hard and heavy. Its density is greater than water and thus sinks; it does not float downstream in washes and must be moved by current motion. Due to its considerable hardness, processing desert ironwood is difficult. Final treatment of the wood with solutions can also be difficult because of its high density.
The reddish wood is very similar in strength and weight to that of Black Walnut (Juglans nigra), with a specific gravity of 0.55, [9] and is now sought for use in wood carving and furniture. [6] Koa is also a tonewood , [ 15 ] often used in the construction of ukuleles , [ 16 ] acoustic guitars , [ 17 ] and Weissenborn -style Hawaiian steel ...
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...
When wounded, the tree exudes a sticky, white latex. The white-coloured wood is hard and durable. The fruit are consumed by the kererū (New Zealand pigeon), and the kākā parrot, both of which were represented on Norfolk Island by closely related birds which are now extinct. [4] [5]
