Balsa
Ochroma pyramidale • Hardwood
Grain Pattern
Generally straight with a medium to coarse texture; visible fuzziness and loose fibers indicate a low-density cell structure.
Color Description
Pale white to oatmeal or light pinkish-buff; sapwood is not clearly distinct from heartwood; lacks significant luster and typically does not change color significantly with age.
Hardness Rating
Approx. 75-100 lbf; Very Soft (specifically the softest commercial hardwood).
Durability Rating
Non-durable; very susceptible to rot, decay, and insect attack if not treated or kept dry.
Common Uses
Model building (airplanes, boats), insulation, flotation devices, film props (breakaway furniture), and core material in sandwich construction.
Geographic Origin
Native to southern Mexico to southern Brazil; commercially grown primarily in Ecuador.
Market Value & Sustainability
Estimated Market Value
$10.00 - $20.00 per board foot depending on density and grade (often sold in small hobby dimensions).
Wood Age Estimate
Relatively recent; likely a modern commercial hobby-grade strip with minimal oxidation or patina.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; generally considered sustainable and fast-growing.
Workability
Easily cut with a craft knife or razor; very prone to crushing and fuzzy surfaces if tools are not extremely sharp; glues easily but absorbs much glue due to porosity.
Notable Features
Extraordinarily lightweight; high strength-to-weight ratio; feels almost like cork or styrofoam; lacks a distinct scent.
Finish Recommendations
Sanding sealer or dope is typically used in hobby applications; absorbs heavy finishes like sponge; finish is often avoided to maintain light weight.
Identification Confidence
High; the extreme fiber shredding (fuzzing), pale uniform color, and visible porosity are hallmark characteristics of Balsa wood.
