Having introduced balsa
wood's history and original status,now we give a outlooking of the
properties and usages of it. We should start our topic with the
introduction of the balsa wood's
lightness. You know that it is exactly owing to its lightness that we
apply it in the model plane and kinds of toys. In the more macro
applications,it would be the case of a real aircraft.
When you want to know exactly the secret to balsa wood's lightness,you
have to seek a microscope for help. You may see that the cells are big
and very thinned walled. So the ratio of solid matter to open space is
as small as possible. The balsa is strong enough though light weight it
is. To give a balsa tree the strength it needs to stand in the
jungle,nature pumps each cell in the wood full of water until they
become rigid - like a car tire full of air. Before it can be sold,the
green balsa wood must therefore be carefully kiln dried to remove most
of the water.
The usages of the balsa wood is wide and broad around the word,making
floats and rafts and in crafts for example. When it comes to the
weight,the balsa wood is not the lightest one. However,combine the
strength with weight,balsa is the most suitable material for the
construction. This is the point where most people confused when they
just learned that compared to other woods,balsa is only about the third
or fourth lightest wood in the world. Density and cuts constitute the
two main properties which can help you select and utilize the balsa in
our daily life.
Frankly speaking,the balsa is considered the strongest material with the
light weight. So if you are in the construction fields,you are
suggested to use it. When it comes to choose it,here is a website for
