Eschweilera truncata 树在商业上被称为 Matamatá，数量丰富，广泛分布在整个森林中，具有森林管理的重要特征，但由于缺乏对揭示其潜力的技术属性（例如其加工和物理特性）的研究而没有被砍伐。否则，此类研究可能有助于将新物种纳入市场，加强森林生态系统的可持续性。鉴于这一差距，本研究旨在评估玛塔玛塔木材在木材工业这一领域使用的加工过程中的物理特性和行为方面的性能。该研究涉及对树的研究，从树上取下基盘，以分析其表观密度、密度、收缩率和各向异性系数。可交易轴被分成原木和木板，以评估加工工艺的影响。在数据分析中，我们使用了描述性统计和Tukey检验。获得的结果将 Matamatá 木材分类为高密度，并确定其各向异性系数为 1.90，表明稳定性为中到低。蒺藜木在机械加工评估中表现出色，在刨床、砂纸、钻头穿孔、顶部框架和车床测试中的成绩也很突出；此外，无论是心材还是边材，它始终呈现出相同质量的木质材料。这是木材产量的一个重要指标，意味着可以更好地利用木材。木材的性能通过家具、装饰品和乐器指板等产品的制造得到验证。一般来说，可以得出结论，所研究的木材可能用于木材工业，因为它具有与已经上市的物种相似的特征，并且因为它在整个亚马逊地区都有丰富的资源。
Eschweilera truncata trees, known commercially by the name of Matamatá, are abundant, widely distributed throughout the forest, and characterized by important features for forest management, but are not harvested due to the scarcity of studies of the technological attributes that would reveal their potential, such as their machining and physical properties. Otherwise such studies might contribute to the inclusion of new species in the market, strengthening the sustainability of the forest ecosystems. Given this gap, the present research aimed to evaluate the performance of Matamatá wood in terms of its physical properties and behaviour under the machining process that would be used in this sector of the timber industry. The research involved a study of the tree, from which a base disk was removed in order to analyse its apparent density, density, shrinkage and anisotropy coefficient. The tradable shaft was split into logs and planks to assess the effects of machining processes. In the data analysis, we used descriptive statistics and the Tukey test. The results obtained classify Matamatá wood as high density and identify its anisotropy coefficient of 1.90, suggesting a medium to low stability. E. truncata wood performed excellently in the machining evaluation, and its results in the planer, sandpaper, drill perforation, frame in the top and lathe tests were also outstanding; in addition it presented wood material of the same quality throughout, whether heartwood or sapwood. This is an important indicator of wood yield, signifying that greater use can be made of the wood. The performance of the wood was validated via the manufacture of products such as furniture, decoration and finger-boards for musical instruments. In general, it can be concluded that the wood studied may be used in the lumber industry, because it presents similar features to those in the species already marketed and because it is plentiful all over the Amazon region.
