Janka side hardness is 690 lb and the Forest Products Laboratory toughness is 118 in.-lb (5/8-in. specimen).
Drying and Shrinkage: Lumber has a marked tendency to collapse during seasoning. Close piling for air-drying and the use of high humidities and low temperatures during the early stages of kiln-drying are suggested. Veneers are slow to dry. Jet-drying of 1/16-in. veneer at 285 °F resulted in buckling, collapse, and splitting. Kiln schedule T2-C2 is suggested for 4/4 stock and T2-C1 for 8/4. Shrinkage green to ovendry: radial 4.0%; tangential 8.5%; volumetric 11.7%. Movement of seasoned wood is classified as large.
Working Properties: Haiari is reported to work easily and finish satisfactorily. Nail withdrawal resistance is higher than would be expected from its density. Rotary cutting trials of 1/16-in. veneer gave smooth surfaces and uniform thickness; rough cutting occurred in 1/8-in. veneer. Reported to have rather unfavorable gluing properties when made into plywood.
Durability: Reported to be highly resistant to decay, but freshly cut logs are very susceptible to damage by pin-hole borers.
Preservation: Both sapwood and heartwood very easy to treat. Absorptions over 9 pcf with uniform penetration obtainable by hot and cold bath as well as pressure- vacuum systems.
Uses: Haiari is suitable for interior construction, boxes, crating, general construction, plywood, and other uses requiring an easily worked wood of moderate strength.

(Spanish), Cabiuna, Caviuna, Jacarandá (Brazil).
Distribution: Of scattered occurrence in the eastern forests of the State of
Bahia and southward to Espirito Santo and Rio de Janeiro and inland to include
Minas Gerais. Because of long-time exploitation, the tree has become very scarce
in the more accessible regions.
The Tree
Sometimes attains a height of 125 ft, with short irregular bole, often
buttressed, trunk diameters 3 to 4 ft. Old trees are generally hollow and also
lose much of their volume when the undesired sapwood is hewed off. Old defective
stems yield the most attractive wood.
The Wood
General Characteristics: Heartwood is various shades of brown to chocolate or
violet, irregularly and conspicuously streaked with black; dark specimens with
oily or waxy appearance and feel; sharply demarcated from the white sapwood.
Grain generally straight; texture medium to rather coarse; luster medium;
fragrant rose-like odor, taste distinctive.
Weight: Basic specific gravity (ovendry weight/green volume) ranges from 0.62 to
0.73; air-dry density 47 to 56 pcf.

12% 20,200 2,130 11,210
Janka side hardness 1,540 lb for green material and 2,040 lb at 12% moisture
content.
Drying and Shrinkage: Wood dries very slowly with a marked tendency to check,
split, and warp; honeycomb may develop in thick material. Kiln schedule T2-C2 is
suggested for 4/4 stock and T2-C1 for 8/4. Air-drying should precede kiln-drying.
Shrinkage green to ovendry: radial 3.6%; tangential 6.9%; volumetric 10.0%.
Working Properties: Though the wood has a high density, it is easy to work with
hand and machine tools; however, high gum exudation clogs saw teeth and cutters.
Once kiln dried, gum exudates are not a serious problem in machining; glues and
polishes well.
Durability: Heartwood is reported to be very durable, resistant to subterranean
termites, and fairly resistant to dry-wood termites. Resistance to marine borers
is low.
Preservation: Extremely resistant to preservation treatments.
Uses: Heavy construction, railroad crossties, poles (sapwood peeled), industrial
flooring, tank staves, and highly favored for charcoal.

Other Common Names: Balsa (Central and South America in general), Corcho
(Mexico), Gatillo (Nicaragua), Enea, Pung (Costa Rica), Lana (Panama), Pau de
balsa (Brazil), Palo de balsa (Peru), Tami (Bolivia).
Distribution: Widely distributed in tropical America; throughout the West Indies,
and from southern Mexico, through Central America and into Venezuela, Colombia,
Brazil, Ecuador, Peru, and Bolivia. Usually found at lower elevations especially
on bottom-land soils along streams; also in clearings and cutover forests.
Cultivated in plantations.
The Tree
Native trees are 60 to 90 ft high and 2.5 to 4 ft in diameter. On the best sites
may reach a height of 80 ft and a diameter of 2.5 ft in 5 years. Slight
buttresses develop in the larger trees.
The Wood
General Characteristics: Heartwood pale brown or reddish; sapwood (comprising
most of the commercial timber) nearly white or oatmeal colored often with a
yellowish or pinkish hue. Texture medium to coarse; grain generally straight;
luster mostly rather high; velvety feel; without distinctive odor or taste.
Weight: Basic specific gravity (ovendry weight/green volume) varies greatly,
commercial balsa usually between 0.10 to 0.17. Air-dry density about 8 to 14 pcf,
averaging in the trade 10 pcf.
