Coarse texture, mostly straight grain except in proximity to knots.

From medium to high.

Mechanical characteristics.
Axial compression strength 50 N/mm² on average; bending strength 105 N/mm²; hardness from medium to high; the impact behaviour is good.

Modulus of elasticity.
12,500 N/mm²

Most frequent structural defects and alteration.
Irregular shape of the trunks, abundance of big knots, internal stresses.
