Balsa
Ochroma pyramidale • Hardwood
Grain Pattern
Straight, with a medium to coarse texture; open-pored appearance with visible vessel elements
Color Description
Pale cream to off-white, sometimes with an oatmeal-like or slightly pinkish-tan hue. Low luster and no distinct heartwood/sapwood transition in visual samples.
Hardness Rating
70-100 lbf (Very Soft)
Durability Rating
Non-durable; highly susceptible to rot, insect attack, and fungal staining if not kept dry
Common Uses
Model building, aircraft construction (cores), surfboards, insulation, stage props, and flotation devices
Geographic Origin
Tropical regions of the Americas, from Southern Mexico to Brazil, with much of the commercial supply originating in Ecuador
Market Value & Sustainability
Estimated Market Value
$10.00 - $25.00 per board foot (varies significantly by density and grade)
Wood Age Estimate
Relatively recent/modern (under 5 years) based on lack of significant oxidation and fresh, light surface color
Sustainability Status
Not listed on CITES or IUCN Red List; generally considered highly sustainable due to rapid growth and plantation harvesting
Workability
Very easy to cut with hand tools (knives/razors) but can crush rather than cut if blades are not sharp; does not hold nails/screws well; glues exceptionally well
Notable Features
Extremely low density/high buoyancy; excellent strength-to-weight ratio; minimal scent; may contain allergenic dust during sanding
Finish Recommendations
Sanding sealer or light lacquer; avoid heavy stains or oil finishes which can be absorbed excessively and increase weight dramatically
Identification Confidence
High; the combination of extremely light color, distinct large vessel pores, and the visible fibrous texture is characteristic of commercial Balsa.
