What is the density of balsa wood?
Balsa wood is the lightest and softest commercial hardwood timber. White to oatmeal in colour with high silky lustre. Density 160 (120-220)kgm3, commercially preferred density range 120-160kgm3. Strength and stiffness approximately 50% that of Baltic pine (Pinus sylvestris).
How much does balsa wood weigh in grams?
Balsa, Hard weighs 0.28192 gram per cubic centimeter or 281.92 kilogram per cubic meter, i.e. density of balsa, Hard is equal to 281.92 kg/m³. In Imperial or US customary measurement system, the density is equal to 17.59969 pound per cubic foot [lb/ft³], or 0.16296 ounce per cubic inch [oz/inch³] .
How much does balsa wood weigh?
On the other hand, you can also find balsa which will weigh 24 lbs or more per cu. ft. However, the general run of commercial balsa for model airplanes will weigh between 6 and 18 pounds per cu. ft.
What is the density of balsa wood in kg m3?
roughly 60 to 380 kg/m3
The density of balsa ranges from roughly 60 to 380 kg/m3; the large density variation derives largely from the fibers, which decrease in edge length and increase in wall thickness as the density increases.
Is balsa wood expensive?
Pricing/Availability: High quality Balsa (that is, Balsa with a very low density) can be rather expensive when purchased at hobby stores or other specialty outlets. Larger boards and lumber sold through typical hardwood dealers is hard to find, but generally has a better cost per board-foot than other sources.
What wood has the highest density?
Wood products The densest of all woods is Allocasuarina luehmannii. Krugiodendron typically has a higher density, among many other woods that vary by sample. Various other hardwoods may also be called lignum vitae and should not be confused with it.

What is the lightest wood?
The Lightest Wood Options
- Redwood – It’s one of the lightest and most durable woods used for building.
- Cedar – At just 19.7 to 23 pounds per square foot (dry) Cedar is one of the lightest woods.
- Cypress – Like Cedar and Redwood Cypress is a lightweight softwood that is durable and resistant to water damage.

What are the disadvantages of balsa wood?
Disadvantage. The durability of Balsa wood is not very much so that we cannot make the furniture used in our house from this wood. If this water gets spoiled when there is too much water, then we cannot use it even outdoors. This wood is light as well as highly flammable so that it soon burns when exposed to fire.
What is the density of wood in kg m3?
Density of Wood
| Type of wood: Hard | kg/m3 | g/cm3 |
|---|---|---|
| Walnut | 641-689 | 0.64-0.69 |
| Mahogany | 497-849 | 0.50-0.85 |
| Maple | 625-753 | 0.63-0.75 |

What is the wood density?
In the present study, wood density is technically defined as the ratio of the oven-dry mass of a wood sample divided by the mass of water displaced by its green volume (wood specific gravity, or WSG). This can be calculated from measurements of oven-dry weight combined with measurement of green volume.
What is the density of a sheet of balsa?
A 3/16″ x 3″ x 36″ sheet of balsa has a volume of 20.25 cubic inches (in 3), which is equal to 0.01171875 cubic feet (ft 3). A piece of balsa with a density of 8 lbs/ft 3 is the same as a density of 128 oz/ft 3. So, to find the weight of the balsa sheet, multiply 128 oz/ft 3 by 0.01171875 ft 3 to get 1.500 oz.
How much does a balsa of wood weigh?
Most balsa from hobby shops is in the 8-10 lbs/ft 3 realm. The rock-hard stock that nobody wants is sent to the airplane kit manufacturers 😉 Before being discovered as an ideal source of wood for model airplanes, balsa trees were cut and assembled into raft for floating down the river.
How big is a balsa tree when it is harvested?
The trees are harvested after six to 10 years of growth. The name balsa comes from the Spanish word for “raft”. Balsa lumber is very soft and light, with a coarse, open grain. The density of dry balsa wood ranges from 40–340 kg/m 3, with a typical density around 160 kg/m 3. The wood of the living tree has large cells that are filled with water.
How is the density of a pound of Wood expressed?
The density is expressed in 10 3 kg/m 3 and (lb/ft 3).
How to calculate balsa density?
By far the simplest method of density calculation for balsa wood is using metric. density in kg/m3 = weightkg / (lengthm x width x thickness) As an example, let’s say you have a sheet of balsa, 920mm x 100mm x 6mm and it weighs 56g, we use the above formula density = 0.056kg / (0.92m x 0.1 x 0.006)
What is the mass of balsa wood?
Balsa is occasionally found weighing as little as 4 lbs. per cu. ft. On the other hand, you can also find balsa which will weigh as much as 24 lbs. or more per cu. ft. However, the average weight of commercial balsa will weigh between 6 lbs. to 18 lbs. per cu. ft. Eight to twelve lb.
Finished balsa wood, like you find in model airplane kits, varies widely in weight. Balsa is occasionally found weighing as little as 4 lbs. per cu. ft. On the other hand, you can also find balsa which will weigh 24 lbs or more per cu. ft.
What are the properties of balsa wood?
Physical properties of balsa: Balsa is a very light and low density type of wood. It is very soft, so soft that you can easily dent it with your fingernail and leave a permanent dent. Since it is not very strong by itself, it’s usually sandwiched between some stronger and harder plies or composite layers which gives the blade strength.
