Environmental Profile
The environmental status of this species within its geographical range has not been officially determined.

Distribution
Coigue (Nothofagus dombeyi) is reported to occur from latitude 38 degrees south northward along the coast of Chile, and up the river valleys into the high cordilleras in northern Llanquihue. It is adapted to poor soils. Rauli (N. procera ) is reported to grow from the Province of Valparaiso to the Province of Valdivia, and thrives mostly on good soils.

Product Sources
It is not known at present whether some material from this species is available from sustainably managed, salvaged, recycled, or other environmentally responsible sources.

Tree Data
Nothofagus trees are reported to 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).

Sapwood Color
The sapwood is described as light brown in color.

Heartwood Color
The heartwood varies from pale pinkish-brown to reddish-brown to bright cherry red in color.

Grain
The grain is usually straight. 

Texture
The texture varies, but it is reported to be often fine and uniform.

Luster
Luster is typically low to medium.

Odor
There is no distinctive odor or taste. 

Ease of Drying
Wood of Coigue (N. dombeyi ) is reported to be generally difficult to dry, while Rauli (N. dombeyi ) tends to dry at a slow rate, with little degrade.

Drying Defects
The wood of Coigue is reported to be prone to collapse and twist. Air drying prior to kiln drying has been suggested.

Kiln Schedules
Coigue - T2-C2 (4/4); T2-C1(8/4) US
Schedule B(4/4) United Kingdom

Rauli - T6-D2 (4/4); T3-D1 (8/4) US

Movement in Service
The timbers are reported to have very good dimensional stability after seasoning, and show negligible movement after manufacture.

T/R Ratio
1.75
This indicator is more meaningful if it is used together with other drying information and actual shrinkage data in the tangential and radial directions. (Refer to the Numerical Values window).

Natural Durability
Natural resistance to decay is reported to vary with species. 

Resistance to Impregnation
Heartwood resistance to preservative treatment is rated as moderate, but the sapwood is permeable.

Planing
Nothofagus timbers are reported to be generally easy to work. They plane, turn, bore, mould, and mortise well to yield clean surfaces.

Carving
Carving qualities are reported to be good. 

Gluing
The timbers have good gluing properties.

Sanding
The wood can be sanded easily. 

Steam Bending
Steam bending properties are rated from fair to good. 

Strength Properties
Bending strength in the air-dry condition (about 12 percent moisture content) is high - comparable to Teak. Strength in compression parallel to grain is in the high range. Other species in this range include Teak, White oak, and Hard maple. It is fairly hard, resisting wear, denting, and marring fairly well. The density is high.
