Product sources: The ITTO reports that the species is a very important source of timber. The timber is exported regularly from Brazil to China and Japan.
Environment profile: Widespread
Tree size: Tree height is 10-20 m
Sometimes develop swollen bases. Trunks are usually cylindrical and somewhat straight and clear
Colors: the heart isWhite to cream, Yellow to golden-yellow to orangeand the sapwoodWhite, White to yellow.The grain isWeak figure, the textureMedium coarse to coarseand the lusterPronounced
Natural durability: Very low natural resistance to decay and attack by termites , Vulnerable to insect attack
Odor: No specific smell or taste
Kiln Schedules: Drying (speed) is fast
Drying Defects: Slight spring/bow, Slight surface checking
Ease of Drying: Fairly Easy
Tree Identification: Bole/stem form is straight
Comments: Copaia wood is reported to compare favorably to White pine in cleavage properties. It is harder than White pine, but is inferior in tension perpendicular to grain, modulus of rupture, impact strength or shock resistance, and shearing strengthGeneral finishing qualities are rated as good
Blunting Effect: Little dulling effect
Boring: Woolly surfaces common in both green and dry material
Carving: Good carving properties
Cutting Resistance: Tendency to splinter
Gluing: Good properties
Mortising: Requires very sharp cutting edges
Moulding: Requires very sharp cutting edges
Movement in Service: Requires very sharp cutting edges
Nailing: Holds nails well, Nails hold poorly
Planing: Planes to a poor finish
Resistance to Impregnation: Heartwood is permeable
Penetration and retention of preservatives are adequate in the heartwood
Response to hand tools: Responds Readily
Routing recessing: Fairly Easy to Very Easy
Sanding: Good sanding qualities
Veneering qualities: Suitable for peeling, Suitable for slicing
Screwing: Easy to screw
; Turning: Fairly Easy to Very Easy
Polishing: Very Good to Excellent;
