Janka
Hardness of Domestic wood species is the industry
standard for gauging the ability of various
wood species to tolerate denting and normal
wear, as well as being a good indication of
the effort required to either nail or saw
the particular wood.
{slide=The Janka Hardness of Domestic Wood species
measures} the force required to push a steel
ball with a diameter of 11.28 millimeters
(0.444 inches) inside the wood to a depth
of half the ball's diameter (the diameter
was chosen to produce a circle with an area
of 100 square millimeters).
the results
were expressed in units of pressure, but when
the ASTM standardized the test (tentative
issue in 1922, standard first formally adopted
in 1927), it called for results in units of
force.The results for the janka hardness are
stated in various ways in different countries,
which can lead to confusion, especially when
the name of the actual units employed is often
not attached. In the United States, the measurement
is in pounds-force(lbf) .
The hardness of wood usually varies with the
direction of the grain remember that is usually
3 popular wood cuts . If the Janka Hardness
test is done on the surface of a wood plank,
with the force exerted perpendicular to the
grain, the test is said to be of "side hardness."
Side hardnesses of a block of wood measured
in the direction of the tree's center (radially)
and on a tangent to the tree's rings (tangentially)
are typically very similar. End testing is
also sometimes done (that is, testing the
cut surface of a stump would be a test of
end hardness).
Moisture Content is always a variant on any
janka hardness test or table this mean that,
side hardness increases with decreasing moisture
content.
In short in the Janka hardness The higher
the number, the harder the wood.
Ash White or Scientific Name: Fraxinus americana
Properties: White ash is elastic and hard,
and it has excellent shock-resistance. The
wood remains smooth under friction. Janka
Hardness: 1320 Beech or Scientific Name: Fagus grandifolia
Properties: Beech is frequently
used in factory floors and other high-traffic
areas, since it wears well and stays smooth
when subjected to repeated friction. The
wood is hard and elastic, with excellent
shock-resistance. Janka Hardness: 1300
Birch
or Scientific Name: Betula spp.
Properties: Birch is a very heavy, strong,
durable wood. It is hard and stiff, with
excellent shock-resistance. Janka Hardness:
1260
Cherry
(Black) or Scientific Name: Prunus serotina
Properties: A strong but moderately hard
wood with excellent shock resistance, black
cherry is generally considered too soft
for an entire floor; mainly it is found
in borders and accents. Janka Hardness:
950
Douglas
Fir or Scientific Name: Pseudotsuga menziesii
Properties: Douglas Fir has
little natural resistance to termites or
decay, and as such should be treated as
a preventative measure. The wood remains
smooth under friction and is reported to
have no odor. Douglas Fir dries rapidly
with little degrade resulting from the process.
Janka Hardness: 710
Hickory-Pecan
or Scientific Name: Carya spp.
Properties: Prized for their resiliency,
both hickory and pecan wood are exceedingly
high in shock resistance, and they rank
as the hardest of all North American hardwoods.
Their combination of stiffness, toughness,
hardness, and durability can be found in
no other commercial wood, which is why they
are used when an extremely hard and durable
wood floor is desired. Janka Hardness: 1820
Maple
Sugar-Hard or Scientific Name: Acer saccharum
Properties: Like black maple
(B. nigrum), sugar maple is classified as
a hardwood (other species of maple are considered
soft). And like teak and white oak, it has
a high crushing strength. It is stiff, strong,
dense, and extremely tough, with excellent
shock resistance. It is notably resistant
to abrasive wear; and for this reason, it
is the hardwood flooring of choice for such
high-traffic/hard-use locations as bowling
alleys, basketball courts, and other sports
facilities. Janka Hardness: 1450
Mesquite
or Scientific Name: Prosopis spp
Properties: In addition to its warm reddish
tint, this moderately lustrous wood is notable
for its hardness and durability Mesquite
is extremely dense wood and very strong.
Janka Hardness: 2345
Red
Oak or Scientific Name: Quercus rubra
Properties: White oak is slightly harder
than red oak, and also more durable. However,
both types are notably stiff and dense,
have high shock resistance, and resist wear.
Because of the high concentration of tannic
acid in white oak, it is particularly resistant
to fungi and insects. Janka Hardness: 1290
Pine
Antique-Heart or Scientific Name: Carpinus
betulus Properties: Pine species
do not usually have a high resistance to
decay, but they do have a propensity to
absorb preservatives rather well. The wood
commonly has no odor. Most pine species
are not difficult or time consuming to dry
properly. Janka Hardness: 1225
Pine
Southern-Yellow or Scientific Name: Pinus
taeda Properties: Pine species
do not usually have a high resistance to
decay, but they do have a propensity to
absorb preservatives rather well. The wood
commonly has no odor. Most pine species
are not difficult or time consuming to dry
properly. Janka Hardness: 870
Pine
Antique-Heart or Scientific Name: Carpinus
betulus Properties: Pine species
do not usually have a high resistance to
decay, but they do have a propensity to
absorb preservatives rather well. The wood
commonly has no odor. Most pine species
are not difficult or time consuming to dry
properly. Janka Hardness: 1225
Walnut
American Black or Scientific Name: Juglans
nigra Properties: This is one
of the most prized of North American hardwoods.
Although American black walnut is somewhat
softer than northern red oak, the wood is
heavy, hard, and stiff and has excellent
dimensional stability. It is moderatly dense,
but very strong, with good shock resistance.
Walnut is one of the most durable of the
domestic commercial woods, even under conditions
favorable to decay. Janka Hardness: 1010
