Resumo

The Australian cedar (Toona ciliata M. Roem) is a species of high commercial value, with characteristics similar to native mahogany and cedar, which has been highlighted in forest plantations in Brazil, whose wood should be the subject of technological research. The objective of this study was to evaluate the physical, chemical and mechanical properties from planted stands of 18 years old. The wood showed low density (0.330 g cm3), low average dimensional stability (anisotropy: 2.22), high content of extractives (10.33%) and moderate mechanical properties: MOR and MOE to bending: 498 kgf cm-2 and 66,163 kgf cm-2; MOR and MOE for parallel compression: 258 kgf cm-2 and 100.813 kgf cm-2; shear: 82 kgf cm-2 and medium hardness: 208 kgf.
