The Janka hardness test (English: / ˈ dʒ æ ŋ k ə /; [1] German:), created by Austrian-born American researcher Gabriel Janka (1864–1932), measures the resistance of a sample of wood to denting and wear. [citation needed] It measures the force required to embed an 11.28-millimeter-diameter (7 ⁄ 16 in) steel ball halfway into a sample of ...

Red oak rings in at a 1290 on the Janka scale (the higher the number, the stronger the board), and white oak comes in at 1360. Durability: Thanks to the wood’s open grain, wood stains take ...
Allocasuarina luehmannii is a dioecious tree that typically grows to a height of 5–15 m (16–49 ft) and has furrowed bark. Its branchlets are more or less erect, up to 400 mm (16 in) long, the leaves reduced to scale-like teeth 0.5–1 mm (0.02–0.04 in) long, arranged in whorls of ten to fourteen around the branchlets.
A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .
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.
Norway maple sits ambiguously between hard and soft maple with a Janka hardness of 1,010 lbf or 4,500 N. The wood is rated as non-durable to perishable in regard to decay resistance. [14] In Europe, it is used for furniture, flooring and musical instruments, especially for violins.
