Introduction to Balsa Wood
Balsa wood, known scientifically as Ochroma pyramidale, is very light. It is used in many industries and crafts. It grows in the rainforests of Central and South America. People love it for its ability to float and its strength.
What is Balsa Wood?
Balsa wood is unique because it’s so light and soft. It is perfect for different projects. It weighs about eight to twelve pounds per cubic foot. This makes it not too heavy for use.
About 40% of balsa lumber is solid, and 60% is space inside it. This space comes from its thin cell walls. The wood is dried to 6% moisture before it’s sold. This makes it good for many uses.
Origin of the Term “Balsa”
The word “balsa” comes from the Spanish word for “raft.” This is because it’s good at floating. Balsa wood mostly comes from Ecuador’s rainforests. Ecuador exports it all over the world.
Ecuador supplies more than 95% of the world’s balsa wood. The balsa tree grows fast, up to 28 meters tall in 6-10 years. It’s a fast and green option for many industries, including model making and aviation. Its moisture content is high when it’s young. This adds to its many benefits.
