The Janka test measures the force used to dig a 0.44 steel ball into a piece of wood. Janka hardness tests are often required to determine the suitability of wood for flooring. Is the Australian Buloke the Hardest Wood Around the World? Australian Buloke wood is the hardest commercially available wood in the world. Australian Buloke. Australian Buloke is a hardwood that is native to Australia and is known for its incredible strength and durability. It has a Janka hardness rating of 5,060 lbf, which makes it the world's hardest wood. It is so strong that it is often used in the construction of bridges, railway sleepers, and even knife handles. Written by Carl Mueller in General. The Janka Hardness Test refers to the pounds force (lbf) required to push a 0.444″ (11.28 mm) diameter steel ball halfway into a sample of wood to mimic the difficult of denting the specimen. It measures the resistance and hardness of wood and is named after its Austrian-born inventor Gabriel Janka. The Janka scale, simply put, records the density of wood by testing its resistance to denting. The test measures the force required to embed a .444-inch (11.28mm) diameter steel ball halfway into a piece of wood. That force is recorded in pounds-force (lbf) in the U.S. or in kilograms-force (kgf) or newtons (N) in other parts of the world. Know Your Wood: Australian Buloke. Australian Buloke. The Australian Bull Oak tests out as the most difficult to penetrate by at least one measure. Common trade names: buloke, bull-oak. Genus: Allocasuarina luehmannii. Janka Hardness (pounds-force): 5060. Description: Possibly there exist limitations to what a woodworker will endure. The Janka rating is an industry-standard for testing the hardness and durability of a wooden floorboard or surface. The higher the rating the more durable the floorboard is, but don't let that be the only defying factor when it comes to choosing your floor.
