Janka
hardness for imported wood species
The Janka Hardness of Imported 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).
In the Janka's original test, 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.
Janka Hardness of Imported 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.
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 plain sawn, quarter sawn
and rift sawn . 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). The most
common use of Janka
hardness ratings is to determine
whether a species is suitable for
use as wood
flooring or contruction frame.
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.
Imported wood species types
Bambo
or Scientific Name: Phyllostachys
vivax Properties: Bamboo
is a renewable resource due to its
short growth time requirement. It
only takes about four years from planting
to harvest time to prepare it for
flooring applications. This flooring
also has the added benefit of being
highly resistant to moisture absorbtion.
Therefore if humidity is an issue,
bamboo flooring offers a material
which will remain true in shape. Janka
Hardness: 1180
Brazilian Cherry or Scientific Name:
Hymenaea courbaril Properties:
In addition to its warm reddish tint,
this moderately lustrous wood is notable
for its hardness and durability jatoba
is extremely dense wood and very strong.
Janka Hardness: 2350
Bubinga or Scientific Name: Guibourtia
spp Properties: Bubinga
wood is durable and has a natural
resistance to termites. This species
requires time and care to dry properly.
If adequate time is not provided,
warping can occur. The wood is not
reported to have any distinctive odor.
Janka Hardness: 2690
Cork or Scientific Name: Quercus suber)
Properties: Cork 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
Cork are not difficult or time consuming
to dry properly. Janka Hardness: 380
Curmaru or Scientific Name: Un/know
Properties: Works well,
but is very hard use carbide blades
and bits. Janka Hardness: 3540
Cypress or Scientific Name: Callitris
glauca Properties: This
species grows in a semi-arid area
of Australia, which bestows on it
the unique property of being the only
commercial softwood that is actually
harder than red oak — making it superior
for both residential and commercial
use. Because of its relative hardness
and excellent durability, Australian
cypress wood flooring has very good
dimensional stability; however, in
actual installations, significant
movement can sometimes be seen. Janka
Hardness: 1375
Gum spotted or Scientific Name: Eucalyptus
maculata Properties: Spotted
gum has a high natural resistance
to decay. The wood remains smooth
under friction and is reported to
a slight citrus-like odor. Spotted
gum dries fairly easily. Janka Hardness:
2473
Gum Sidney or Scientific Name: Eucalyptus
saligna Properties: Sydney
blue gum wood is very hard and tough,
and moderately durable. This species
can take some time to dry properly
to prevent checking and warping. Janka
Hardness: 2023
Iroko or Scientific Name: Chlorophora
spp Properties: Iroko
is a very heavy, strong, durable wood.
It is hard and stiff, with excellent
shock-resistance. Janka Hardness:
1260
Jarrah or Scientific Name: Eucalyptus
marginata Properties:
Jarrah is very hard and durable, with
a bending strength much greater than
that of Mahogany. It has moderate
resistance to decay when not chemically
treated. The wood remains smooth under
friction and is reported to be odorless.
Amendoim is a dimensionally stable
wood flooring species. Janka Hardness:
1910
Mahogany (santos) or Scientific Name:
Myroxylon balsamum Properties:
Mahogany is known for its strength
and beauty, and it has outstanding
durability. Given its hardness and
color-fastness, santos mahogany is
a superior choice to genuine Honduran
mahogany (Swietenia macrophylla),
which it closely resembles in color.
In fact, although genuine mahogany
is traditionally chosen for fine furniture
and millwork, it is seldom used in
wood flooring because it lacks sufficient
hardness to withstand constant foot
traffic. Janka Hardness: 2200
Maple (Brazilian) or Scientific Name:
Acer saccharum Properties:
Like black maple (B. nigrum), 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: 1500
Merbau or Scientific Name: Intsia
biuga / Intsia palembanica spp
Properties: Merbau is almost as stable
as teak. And although comparable to
hickory in strength, merbau has a
much lower density. It has excellent
dimensional stability and is highly
resistant to termites. Janka Hardness:
1925
Oak (Tasmanian) or Scientific Name:
Eucalyptus delegatensis
Properties: Tasmanian oak does not
have a natural resistance to decay,
and lacks any noticable odor. Tasmanian
oak requires some care to dry properly
as checking can occur. Janka Hardness:
1350
Padauk or Scientific Name: Pterocarpus
soyauxii Properties: Harder
and more stable than northern red
oak, padauk is heavy and strong and
has an average to high durability.
It has excellent weathering qualities
and is highly resistant to decay.
Janka Hardness: 1725
Purpleheart or Scientific Name: Peltogyne
spp. Properties: Purpleheart
is a very hard, dense, strong wood,
with excellent dimensional stability.
It is very resistant to dry-wood termites.
Janka Hardness: 2890
Sapele or Scientific Name: Entandrophragma
cylindricum Properties:
Sapele is quite durable and seasons
rapidly, but with a marked tendency
to warp, so careful stacking is required.
Janka Hardness: 1510
Teak (Brazilian) or Scientific Name:
Tectona grandis Properties:
Teak has a high resistance to decay
and termite attack. In fact the oil
secreted by the wood is reported to
be a natural insect repellant. The
wood remains smooth under friction
and is reported to have the odor of
leather when freshly cut. Chestnut
is diffuclt and time consuming to
dry properly. Janka Hardness: 3540
Walnut brazilian Ipe or Scientific
Name: Juglans nigra Properties:
the wood is heavy, hard, and stiff
and has excellent dimensional stability.
It is moderatly dense, but very strong,
with good shock resistance. Janka
Hardness: 3680
Wenge or Scientific Name: Millettia
laurentii Properties:
Like black maple (B. nigrum), 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.
