The wood is red brown with clearly demarcated sapwood. Possible brittleheart and sometimes presence of white streaks (resin canals). The grain is straight or interlocked and the texture is medium. Density at 12 % moisture content: 0.80 g/cm3.
The blunting effect is fairly high and peeling and slicing is not recommended or without interest. Nailing is good but pre-boring is necessary. Risk of splitting in nailing. Gluing is correct. Resin may clog the tools and may have a blunting effect. Filling is recommended to obtain a good finish. Drying rate is normal and thin stocks must be dried with care to prevent distortions.
Alan Batu is moderately durable to fungi and it is durable to dry wood borers; sapwood demarcated (risk limited to sapwood).
