Capacity of being impregnated
- Sapwood: Medium capacity of being impregnated
- Heartwood: Low capacity of being impregnated
Mechanical properties
- Resistance to static flexion 1,700 kg/cm2
- Elasticity module 140,000 kg/cm2
- Resistance to parallel compression 750 kg/cm2
- Resistance to parallel traction 1,200 kg/cm2
Mechanization
- Sawing process: ordinary difficulties arise from hardness
- Drying process: very slow. High risk of deformation and lower risk of crack formation
- Planing process: Difficult due to its hardness and to the risk of repelling and splinting. Slow mechanisation is highly recommended
- Gluing process: Tannins hamper proper adherence
- Nailing and screwing process: pre-drilling is recommended due to the hardness
- Finish: Rubber deposits can locally inhibit varnish adherence
Physical properties
- Apparent density at 12% humidity 920 kg/m3 very heavy wood
- Dimensional stability
- - Volumetric contraction coefficient 0.52%. It varies from nervous wood to very nervous wood
- - Relation between contractions 1.7% no tendency to deformity
- Hardness (Chaláis-Meudon) 8.5 very hard wood
Observations
- En algunes zones d'Espanya en diuen Bolondo
- A la guia ATIBT figura com a Talí
- A més, quant a preu és una de les que millor posicionada està de totes les espècies recomanades per a exterior.
- A destacar el fet de tenir en estoc també fusta d'amplada fixa el que facilita al fuster el càlcul de costos quan han de passar cotització al client final.
