Color/Appearance: Heartwood is reddish brown, sometimes with
colored streaks; slightly paler sapwood isn’t always clearly demarcated
from the heartwood. Freshly sawn surfaces can have a lighter olive hue,
with color darkening to a deeper reddish brown with age.
Grain/Texture: Grain is usually interlocked, with a uniform, medium-
coarse texture. Moderate natural luster.
Rot Resistance: Rated as durable to very durable, with good resistance
to insect attack.
Workability: Considered to be difficult to work on account of its density
and irregular grain. The wood also has a high cutting resistance with a
pronounced blunting effect on cutters.
Common Uses: Heavy construction (exterior applications), flooring,
decking, boatbuilding, docks, and other applications where its strength
and rot resistance can be utilized.
useful info’s : Angelim is yet another example of a very strong and
dense tropical hardwood coming from South America. Like most of these
hard tropical exotics, it can be a challenge to work, but its durability may
be justification to bear with such an uncooperative wood. Additionally, it
has quite an offensive odor while it is being worked — and the scent is
present both in the green wood and in dried wood.
