Information: ITAUBA >>
Common name: Itaúba
Scientific name: Mezilaurus Itauba
Family: Lauraceae
General characteristics:
Heavy wood, hard and few difficult to saw (stiletted saws reccomended) but easy to smooth, it produces excellent finishing. It has medium and uniform texture and it carries high mechanical resistance and extreme durability. When recently beneficiated, its sift presents olive-yellowish, becoming dark chestnut color with the time. It has uniform color and irregularly lustrous and flat surface to the touch. Its smell is lightly sweetened and pleasant, almost imperceptible in the wood recently beneficiated, disappearing in little time.
Anatomical characteristics:
Obscure axial parenchyma even under scarce lens, vasselcentric, eventually diffuse; seriate, of 2 to 8 cells per series; abundant oil-resin. Visible Pores/vassels under lens as clearer points; diffuse distribution; solitary lightly predominant (58%), happening geminates and radial multiples up to 6; not very numerous, 9 to 22, prevailing from 11 to 20 (80%) pores for mm2; small and medium, 60 to 200 mm, being most between 100 and 200 mm of tangential diameter. Numerous, clear vascular lines and obstructed by tylos and oil-resin; plate of simple perforation; big intervascular punctuations, of 11 to 15 mm diameter, alternating; abundant, obstructed tylos, vascular elements from short to very long, 390 to 500 mm length. Rays in the type, thin, numerous, visible only under lens; in the tangential face, irregularly disposed, visible under lens with a certain difficulty; in the radial face, the rays are not very contrasted; homocellulars with tendency to heterocellulars, with one or two layers of square marginal cells; multiseried, 2 to 4 cells, predominance of 2 to 3 width cells; few to not very numerous ones, 3 to 7, being most from 5 to 7 (90%) rays per mm; extremely low to low 290 to 1630 mm height; 10 to 81 height cells; radiovascular punctuations from 14 to 24 mm diameter, round or oval, with different borders; silica in crystalline attaches and abundant oil-resin. Septed fibers, from short to very long, 1100 to 2200 mm length; narrow and wide, from 18 to 40 mm width, with thick to very thick walls, simple punctuations. oilen cells present and numerous. Obscure growth layers.
Natural durability:
ITAÚBA wood, according to practical observations, is considered of very high resistance to the attack of xylophag organisms.
Preservation Treatment:
ITAÚBA wood, with pores obstructed by oil-resin and tylos, when under pressure treatments, should present very low permeability to preservation solutions.
Main Applications:
ITAÚBA wood, because of being very heavy, of low retractibillity in relation to the density, high mechanical resistance and very high durability, is indicated for external constructions, as structures of bridges, sleepers, posts, crosspieces; in civil construction, as beams, light frames, parquets and floorboards, sills for doors and windows; construction of vehicles and agricultural implements; naval construction, embarkations; production of shaped pieces, pieces of furniture, etc.
