It is adapted to poor soils. Rauli (N. procera) grows from the Province of Valparaiso to the Province of Valdivia, and thrives mostly on good soils.

Dries slowly with little degrade Difficult Wood of Coigue (N. dombeyi ) is generally difficult to dry, while Rauli (N. dombeyi ) tends to dry at a slow rate, with little degrade Tree Size Nothofagus trees attain heights of up to 130 feet (39 m), with trunk diameters that are often 24 to 36 inches (60 to 90 cm), but sometimes reaching 6 to 8 feet (2 to 2.4 m). They develop boles that are often free of branches to about 60 feet (18 m) Blunting Effect Little Boring Fairly easy to very easy Carving Fairly Easy to Very Easy Good results Cutting Resistance Easy to saw Gluing Fair to Good Results Good gluing properties Mortising Fairly Easy to Very Easy Moulding Fairly Easy to Very Easy Movement in Service Very stable after seasoning Small Nailing Fair to Good Results Very Good to Excellent Results Fairly Easy to Very Easy Planing Fairly Easy to Very Easy Yields clean surfaces Easy to plane Nothofagus timbers are generally easy to work.

Strength in compression parallel to grain is in the high range. Other species in this range include Teak, White oak, and Hard maple Numerical Data Item Green Dry English Bending Strength 8161 12444 psi Density 37 lbs/ft3 Hardness 970 lbs Maximum Crushing Strength 3600 6877 psi Stiffness 1317 1656 1000 psi Specific Gravity 0.45 Radial Shrinkage 4 % Tangential Shrinkage 7 % Item Green Dry Metric Bending Strength 573 874 kg/cm2 Density 592 kg/m3 Hardness 439 kg Maximum Crushing Strength 253 483 kg/cm2 Stiffness 92 116 1000 kg/cm2 Specific Gravity 0.45 Radial Shrinkage 4 % References Boone, R.S., C.J.
