Heartwood and sapwood differentiated by color, Heartwood brown or brown-kernel with yellowish or greenish reflections, yellowish-white sapwood; non-gloss surface; imperceptible smell and taste; high density; hard to cut; irregular grain to be reverse; fine texture.
Natural durability: Ipe wood, in laboratory tests, has been shown to be highly resistant to attack by xylophagous organisms (fungi and termites). In an experiment carried out in the marine environment it was moderately attacked by perforating organisms. In field trials, with stakes in contact with the soil, the average life span was 8 to 9 years. In practical observations, it is considered very resistant to decay.
Treatability: under pressure treatment it proved to be impermeable to preservative solutions.
Workability: Ipe wood is moderately hard to work on, especially with hand tools that quickly lose sharpening. Receives a good finish. Glue problems are reported. The planing is regular, easy to sand and excellent for brading and screwing.
Drying: Air-drying is medium to fast and has small cracking and warping problems. Artificial drying using oven can aggravate the incidence of defects.
