Balsa — a deciduous tree from tropical America. He has a very beautiful color of wood. He practical white, with a yellowish or pinkish tint. Balsa is considered the lightest wood in the world, because its density is not more than 160 kilograms per cubic meter. For comparison, the pine density — 520, oak — 760, of Linden — 550.
Another remarkable property of this tree: when felled, wood contains 90 percent moisture. The water quickly dries in the sun and wind, but the trunk and branches don't turn into dust (as, for example, the baobab), and, on the contrary, — gaining the necessary strength. This property makes the balsa tree attractive for industrial applications. The materials from it are lightweight and have excellent sound and vibration damping properties.
What is balsa wood we reviewed. Now we know where most commonly used materials manufactured from it. Great popularity is enjoyed by balsa model airplanes. And this is understandable. Even if you compare balsa with carbon fiber, that tree profitable wins. It is very easy to handle, its cost is extremely low. And balsa has excellent remonopolization.

Is considered ideal wood for the manufacture of brushes for calligraphy. But shipbuilding balsa wood used for the construction of decks and boards for small pleasure craft (usually not exceeding 30 metres in length, the size of an adult tree). Balsa is used for the manufacture of blades for wind turbines. Probably, it is difficult to imagine a more comfortable and lightweight material.
Rabbit or wool wood, cotton — it's all balsa wood, which would be incomplete without a mention of the fruit. Thanks to them he got such funny names. The fruit of balsa — boxes 30-inch length. Inside there is a lot of reddish silky fibers, which are hidden seeds. When is maturing, the bolls burst and flauntyour “inside”.
