It is closer in strength to Mahogany than either Teak or White oak, which have higher bending strength.It is lower in this property ( Compression strength parallel to grain, or maximum crushing strength)than Teak.It resists denting and marring about as well as white oak or birch Berni, C.A., Bolza, E., Christensen, F.J.,1979,South American Timbers - The Characteristics, Properties and Uses of 190,Species,C.S.I.R.O Div.
