balsa is technically classified as a hardwood, rather than a softwood, since it has broad leaves and is not a conifer. balsa has excellent sound, heat, and vibration insulating properties, and is also incredibly buoyant: in fact, balsa is the spanish word for raft. related species: none available.

9.5 pcf, tensile strength 1910 psi (that's pretty strong stuff, a 1" square piece of balsa wood holding one ton of weight) standard grade 60 structural steel is about 500 pcf and has a tensile strength of about 60,000psi (thus the name). tensile strength/density ratios are thus: 1910/9.5 = 201 60000/500 = 120
strength is a material's strength divided by its density. it is also known as the strength-to-weight ratio or strength/weight ratio. in fiber or textile applications, tenacity is the usual measure of specific strength. the si unit for specific strength is pa m/kg, or n·m/kg, which is dimensionally equivalent to m/s, though .
properties of plantation-grown balsa wood from papua new guinea (png) were determined according to american society for testing and materials d143-09. static bending, hardness, compression parallel and perpendicular to grain, and shear parallel to grain tests were performed on kiln-dried .

balsa is a wood-based material. it has the lowest density among wood-based materials. in addition, it has the highest dielectric strength and a moderately low ductility. the graph bars on the material properties cards below compare balsa to other wood-based materials (top) and the entire database (bottom).
