JM - Tropical Wood

Angelim pedra

Ormosia coccinea

Fabaceae-Papilionoideae

When freshly cut the sapwood is a very light brown in color and the heartwood is a yellowish red.

The wood has high basic density with medium linear contractions and stable volumetric contraction. Due to its hardness and mechanical resistance, the wood is somewhat difficult to saw. It rates well for workability, brushing, and molding. Drilling is moderately difficult.
The natural drying process is slow, but the wood behaves well under artificial drying. The natural durability is good. The wood is moderately resistant to biological attack: the sapwood is susceptible, but the heartwood requires no preservation.
Due to the high proportion of sapwood, whilst the logs are large their yield in final product is usually low.

The wood is used in carpentry work, furniture, decorative veneers, floors (tongue and groove parquet, staircase steps), building structures (beams, joists, columns, trusses) and heavy construction (bridges, mine supports, pylons, bodywork, and packaging).
