Botanically, Ipé(Tabebuia ipe and T. serratifolia) and Tajibo(Tabebuia impetiginosa) belong to the Bignoniaceae. Ipé’s natural habitat is the evergreen and semi-evergreen rainforest. Tajibo is more likely to be found in the evergreen rainforests of Mato Grosso and in large parts of Bolivia. Ipé, on the other hand, comes from Brazil. There is often no differentiation in the trade, as the woods practically do not differ in their utility value.
When fresh, Ipé is brown to red-brown, Tajibo is more brown to yellow-green, later darkening to brown-olive, occasionally also dark striped or black-olive. The structure of the wood is homogeneous and dense. The pores are fine and scattered. Frequently pronounced alternating torsion. Selected trunks can also have a straight, even growth habit. Ipé and Tajibo are rather plain but with a natural shine. Overall decorative to very decorative.
The density of both woods at a moisture content of 12% varies between 0.96 and 1.02 t/m3. The swelling and shrinkage values are 6.5% tangentially and 5.2% radially. Despite its high density, the wood has a low shrinkage. Tajibo-Ipé can be dried without any significant problems; however, drying must be slow. The hardness is quite high in accordance with the density and is given as 42 N/mm2 Brinell across the fiber. The modulus of elasticity is 18,200 N/mm2, but can also be higher in some cases. Tajibo and Ipé are among the hardest woods in South America and are used wherever high-quality solutions are required.
Tajibo-Ipé is classified as weather-resistant (durability class 1), but not teredo-resistant, i.e. it is not suitable for use in contact with sea, salt and brackish water.
