Trumpet wood (Cecropia peltata)
Family: Cecropiaceae Common names: Ambahu , Boessi papaja, Bois canon, Cecropia, Cetico, Congo-pump, Guarumo, Imbauba, Pacuna, Trumpet wood, Trumpet-tree, Yagrumo, Yagrumo hembra Distributed in: Argentina, Brazil, Columbia, Cuba, Mexico, Peru, Puerto Rico [US], Suriname, Trinidad and Tobago, Venezuela (Central America, Latin America, Oceania and S.E. Asia) Distribution overview: Throughout tropical America. Abundant in open areas and in forests, both virgin and cutover, often forming almost pure stands. Common uses: Boxes and crates, Charcoal, Core Stock, Excelsior, Fuelwood, Joinery, Matches, Model airplanes, Paneling, Particleboard, Plywood corestock, Plywood, Pulp/Paper products, Pulpwood, Toys, Veneer Environment profile: Rare Tree size: Trunk diameter is 300-350 cm
Colors: the heart isWhite to cream, Yellowand the sapwoodWhite to yellow, Yellow.The grain isStraight, the textureTypically coarse and the lusterSlightly lustrous
Natural durability: The heartwood is susceptible to wood staining fungal attack, The sapwood is susceptible to wood staining fungal attack Odor: No specific smell or taste
Kiln Schedules: Drying (speed) is fast
Kiln Drying Rate: Naturally dries quickly Drying Defects: Slight twist/warp, Splitting Ease of Drying: Slowly Comments: Trumpet wood is similar to the North American Black cottonwood (Populus trichocarpa ) in density and in mechanical properties. Blunting Effect: Moderate Boring: Poor to very poor results Carving: Fairly Easy to Very Easy Cutting Resistance: Fairly Difficult to Very Difficult to saw Gluing: Fairly Easy to Very Easy Mortising: Poor to Very Poor Moulding: Poor to Very Poor Movement in Service: Poor to Very Poor Nailing: Poor to Very Poor , Very Good to Excellent Planing: Very Good to Excellent Resistance to Impregnation: Permeable sapwood Resistance to Splitting: Excellent
Response to hand tools: Fairly Difficult to Difficult to Work Routing recessing: Poor to Very Poor Results Sanding: Very Good to Excellent Results Veneering qualities: Veneers easily, Veneers moderately easy
Screwing: Screwing yields good results, Very Good to Excellent Results; Turning: Turns with moderate ease
Painting: Very Good to Excellent; Polishing: Very Good to Excellent; Staining: Very Good to Excellent; Varnishing: Satisfactory
The wood responds very poorly to varnishes and lacquer.

Max. crushing strength = low 0 Modulus of Elasticity (stiffness) = very low Shrinkage, Radial = very small Shrinkage, Tangential = small Density (dry weight) = 15-22 lbs/cu. ft. Bending strength (MOR) = very low Density (dry weight) = 23-30 lbs/cu. ft. Bending strength (MOR) = low Shearing strength (parallel to grain) = very low Work to Maximum Load = very low Shrinkage, Tangential = very small Shrinkage, Tangential = moderate Shrinkage, Radial = small Hardness (side grain) = very soft Shrinkage, Volumetric = fairly large Shrinkage, Radial = moderate Shearing strength (parallel to grain) = low Compression strength (parallel to grain) = low Surfaces may dent or scratch easily since the wood is soft.
