It measures the force required to embed an 11.28 millimetres (0.444 in) diameter steel ball halfway into a sample of wood. This method leaves a hemispherical indentation with an area of 99999♠200 mm2. A common use of Janka hardness ratings is to determine whether a species is suitable for use as flooring.
Hardwood Flooring Hardness . Having seen changes in the wood flooring business over the years, I never realized how many people were ill-advised of how to actually go about buying wood floors. Phone calls and emails tell the story with hardness being very near the top of the list.
Cabinet Wood Hardness & Durability. Red oak, which is the most common cabinet wood, has a Janka rating of 1290. At the low end of common cabinet woods, Eastern white pine is rated at 380 (for comparison, balsa wood is 100). While the Janka scale is useful in flooring it is not as useful for cabinets. This is because flooring is subject to tremendous stress from people walking on it.
Wood is also tested on the sides or ends, because that provides a different hardness rating, but these ratings are not displayed on the typical hardness scale. What The Wood Hardness Scale Looks Like. The Janka Hardness Scale starts at zero, with this option being the softest wood choice, making it easy to dent and scratch.
The wood hardness scale tells you how hard a particular species of wood is, but is not necessarily reflective of how durable that species is in flooring form. Other factors affecting durability include the thickness of the wood, the protective finish applied, and, for engineered wood flooring , the construction of the core layers.
3 Comments. Typically, red alder is in the range of 2.6-2.7lbs per board foot or 32lbs per cuft. We use several thousand board feet per year in guitar making and rarely see it at 28lbs per cuft. IS GOOD FOR SMOKING FISH. It makes a pretty nice xylophone wood. Easy to shape and tune with a belt sander.
If you're looking for wood flooring that you hope will last for decades, the obvious choice will be for a wood that is naturally hard. It is not enough to simply pick any so-called hardwood species, because hardwoods vary quite a lot in their hardness from species to species, and some are actually softer than some softwood species.
acrylic engineered wood ratings of hardness. Janka Hardness Rating Scale for Hardwood Floors. Where The Wood Hardness Scale Comes From. The scale was developed as a means for displaying the results of the Janka hardness test. The test uses a 2″ x 2″ x 6″ piece of wood and a 0.444″ steel ball to determine how hard the wood is.
Although classified as a hardwood, alder is one of the softest of all hardwoods and is more commonly referred to as a semi-hardwood. On a hardness scale, alder ranks just above pine and poplar.
The Janka scale is used to determine the relative hardness of particular domestic or exotic wood species. The Janka test measures the amount of force required to embed a 0.444" steel ball into the wood to half of its diameter. Woods with a higher rating are harder than woods with a lower rating. The scale used in the table is pounds-force.
The Janka Hardness Test. The Janka Test is a measure of the hardness of wood. The Janka Test was developed as a variation of the Brinell hardness test. The test measures the force required to push a steel ball with a diameter of 11.28 millimeters (0.444 inches) into the wood to a depth of half the ball’s diameter.
Engineered hardwoods have only a 3mm layer of solid wood species on top of a cross-constructed wood grain plank and are therefore exempt from Janka hardness ratings. Even though engineered hardwoods cannot be tested for their Janka hardness rating, they are still extremely durable floors that can withstand every day wear and tear, and can be ...

Hardness Ratings Of Our Wood Choices. Poplar: 540 This wood has a straight, uniform grain that comes in a medium texture. Poplar is a light, almost white colored timber with a soft, low density. The colors can range from a very pale yellow to white, the heartwood and sapwood are hardly distinguishable.
Janka hardness. A measure of the hardness of wood, produced by a variation on the Brinell hardness test. The test measures the force required to push a steel ball with a diameter of 11.28 millimeters (0.444 inches) into the wood to a depth of half the ball’s diameter (the diameter was chosen to produce a circle with an area...
Relative hardness of wood flooring species. Below are listed the relative hardness for numerous wood species used in flooring. These ratings were done using the Janka Hardness Test. The Janka hardness test measures the force required to embed a .444 inch steel ball to half its diameter in wood.
