What is the scientific name of balsa

Balsa wood (Ochroma pyramidale )

Scientific name :
Ochroma pyramidale

The wood type balsa wood is very light and very easy to work with. Balsa wood was used in the country of origin for building rafts, it is a very popular wood for model building (especially for model aircraft and ship models). In addition, balsa wood is often used in sandwitsch construction methods and as surfboards it was used by the Hawaiians (today surfers still appreciate balsa wood surfboards)

Technical properties of balsa wood

The velvety balsa wood is extremely light, soft and elastic. Balsa wood can be cut well, but due to its softness it cannot be planed and file. Not suitable for peeling and knives. Nails hold up with balsa wood and no more screws.

Values โ€‹โ€‹of the technical properties of a type of wood relate to a wood moisture content of u โ‰…12% to 15%.

Dry :

Open air drying is easily possible with balsa wood if the appropriate conditions are observed, with technical drying of balsa wood should be the wood have a uniform initial moisture in the stack. The wood moisture of the felled balsa trunk can amount to approx. 300 to 400% (due to its anatomical structure).

Swelling / shrinking
Tangential:3,5 - 5,3 %
Radial:1,8 - 3,0 %

Occurrence :

Northern South America, also found in Africa and Asia

Tree trunk :

Balsa wood is a fast-growing type of wood that has reached heights of 15-20 m with a diameter of 0.6 to 0.7 m after 6 years. Generally up to 40m high and about 1m in diameter. The shaft of the balsa tree is slim, cylindrical and free of knots up to 2/3 of its height.

Bark soft, gray to white, quite thick, rich in water, cracks in balsa wood with age. The bark content can be around 4%.
The wood type balsa wood is available as FSC.
Wood color :
The sapwood and heartwood are not clearly separated in balsa wood. Sap very broad, almost white, partly with a brownish or reddish sheen. The heartwood is white with a reddish-brown color.
Features :
The pores of the balsa wood are scattered and large, regularly arranged. Medullary rays radial as a mirror, in cross section as a wavy line.
Fungus very low. Insects very few.
not permanent
Use :
Model construction, insulation material for refrigeration technology, aircraft construction, cork substitutes, swimming belts, pith helmets and for paper and cellulose production.
