Intsia bijuga
Merbau (Intsia bijuga) is a medium-hardness wood balancing workability and wear resistance, with a Janka hardness of 851 lbf (3785 N) and a density of about 0.74 g/cm³. It originates from se asia and pacific.
With radial shrinkage of 2.7% and tangential shrinkage of 4.6% (a T/R ratio of 1.7), it is reasonably stable with normal seasonal movement. Its fiber saturation point is around 26%, below which the wood begins to shrink and move as it dries.
