*Pacific Jarrah \ Manilkara bidentata

Other Common Names: Massaranduba, Balata, Bulletwood, Brazilian Redwood, Quinila, Manilkara

 

                                                                                                            

*Family -Sapotaceae



*Description

Sapwood is 30 to 50mm wide, whitish or pale brown anddistinct, but not sharply demarcated from the heartwood which

is light red when freshly cut, turning to dark reddish-brown when dry. Lustre medium. Texture fine and uniform. Grain usually

straight, occasionally interlocked. Characteristic odour when green but no odour or taste noticeable when dry. Boles 15 to

18m long, straight, cylindrical and unbuttressed.


Characteristics

Timber is exceptionally hard, heavy, strong and tough. Must be dried slowly and with care to minimize degrade. Moderately hard

to machine because of its high density but cuts cleanly without appreciable dulling of cutting edges. Turning must be done

slowly to avoid tearing. Moderately difficult to work but can be finished smoothly.

Takes a high polish. Pre-boring necessary for 
nails and screws. Requires care in gluing. Sapwood of green logs

susceptible to pinhole borer attack. Very resistant to fungal and termite attack but liable to attack by marine borers.

Extremely 
resistant to moisture absorption. High resistance to wear.

Uses

Structural timber, Flooring, Mine timber, Ship and boat building,

Vehicle body, Furniture, Cabinet work, Handles and ladders, Sporting

goods, Agricultural implements, Musical instruments, Interior trim,

Sleepers, Poles and piles, Toys and novelties, Turnery.


*Tonka/Dipteryx Odorata

Other Common Names: Cumaru, Brazilian Teak, Southern Spotted

                                   
Family  Papilionaceae


Description
Sapwood is 25 to 50mm wide and yellowish or yellowish-brown in colour. Heartwood reddish-brown or purplish-brown when freshly
cut with attractive paler streaks, turning to a uniform light brown on exposure. Texture is fine, lustre medium and grain irregular,
often interlocked. Wood is characterized by prominent vessel lines and by narrow strikes on radial surfaces. There is no distinct
taste but faint vanilla-like or rancid odour. Appearance waxy. Bole is clear, cylindrical and unbuttressed, up to 24m in length.

Characteristics
Timber is extremely hard and heavy, very strong and tough.Shock resistance high. Relatively easy to season considering
its density. Material has been air-dried under cover in les than 120 days with some surface checking occurring slower rate of
seasoning is likely to reduce degrade. Stock is difficult to work because of its density and hardness.

Hard to saw and bore, but
clean edges and holes can be obtained. Planes and finishes to a smooth surface and takes a high polish.
Glues adequately. 
Resistant to termite and marine borer attack. Heartwood very resistant to preservative treatment.
Useful for cogs, shafts,
bearings, paving blocks and fishing rods.

Uses
Structural timber (heavy), Flooring (heavy), Mine timber, Ship and boat building, Vehicle body, Cabinet work, Handles and ladders,
Sporting goods, Agricultural implements, Sleepers, Poles and Piles Strength group

Durability
(Class 1, very durable) Approximate life in contact with the ground (years), more than 25 years, for conditions significantly different
from that represented 
by ground contact, the life expectancy of the species would obviously be longer than that indicated in this
classification

*White Mahogany
Other Common Name: Congona

Sapwood about 40cm wide, pale yellowish-white or pinkish-yellow. Heartwood is yellowish, yellow-light brown

                                           

Family
Moraceae



Description
Sapwood about 40mm wide, pale yellowish-white or pinkishyellow. Heartwood is yellowish, yellow-light brown. Texture
rather fine. No odour or taste. Latex tubes common. Lumina contains red-brown gummy substance. Growth rings not
distinct. Grain usually straight or wavy. Trunk is buttressed up to 2.4m. Species occurs in upland rain forests, frequently on
sandy soils.

Characteristics

Timber is hard and strong. Seasons without difficulty but must be dried carefully, Moisture movement low. Works with some
difficulty due to its hardness and density. Turns well. Finishes smoothly and polishes excellently. Glues well. Difficult to nail
without pre-boring. Timber is durable and highly resistant to termites. Suitable for tool handles.

Uses
Structural timber, Flooring, Furniture, Cabinet work, Joinery,
Veneer, Plywood, Interior trim, Handles, Turnery.


* Brazilan Walnut

Other Commin Names: Tahuari

                                 

Family
Bignoniaceae



Description
Sapwood relatively thick, yellowish-white and sharply differentiated.Heartwood greyish when freshly cut, darkening to greyish-green or
brownish-olive on exposure; sometimes slightly streaked. Texture fine and uneven. Grain rarely straight, usually interlocked to very
irregular. Lustre medium. Odour and taste not distinct. Vessels of heartwood contain a yellow-green deposit (Lapachol).

Bark contains 
around 5% of tannin. Bole straight, cylindrical, slightly buttressed and unbranched, 18 to 21 mt. (60-70 feet) in length.
Found mainly 
in mixed deciduous and evergreen forests, but may gregariously occur on steep rocky hillsides or in smaller numbers
in lowland 
forests. Often planted as a avenue tree.

Characteristics

Timber is fairly easy to season, drying rapidly with very little warping and checking. Moderately difficult to work with machine
tools. High resistance to cutting, resulting in severe blunting effect on edges. Finishes very smoothly. Difficult to nail; preboring
necessary to avoid splitting. Turns well. Not resistant to termite and marine borer attack. Sapwood permeable, heartwood
extremely resistant to impregnation. Very durable in non-teredo waters. Very good dimensional stability in use and highly resistant
to shock. Makes good firewood. Often used in the round. Dust may cause irritation of skin in some workers.

Uses
Structural timber heavy, Flooring heavy, Mine timber, Ship and
boat building, Vehicle body, Handles, Ladders, Joinery, Sleepers,
Furniture, Cabinet work, Interior trim, Poles, Piles, Turnery.
