Capacity of being impregnated

&;8226; Sapwood: Medium capacity of being impregnated
&;8226; Heartwood: Low capacity of being impregnated


&;8226; Sawing process: ordinary difficulties arise from hardness and the possible irritations produced by its powder. Risk of deformations due to internal tensions that produce radial quartering despieces radiales.
&;8226; Drying process: Medium to high speed. Low risk of deformation and crack formation.
&;8226; Planing process: Difficulties arise from hardness and risk of repelling on pieces of intertwined fibers. Slow mechanisation is recommended
&;8226; Gluing process: No difficulties.
&;8226; Nailing and screwing process: pre-drilling is recommended due to hardness.
&;8226; Finish: No particular difficulties arise
