Wood Technology Transfer Fact Sheet
Other Common Names: Pino (generally in Latin America), Ocote (Mexico, Guatemala, Honduras, Nicaragua).
Distribution: Upper mountain slopes and mountain ridge tops from northwestern Mexico southward to central Nicaragua; most extensively in Guatemala, Honduras, and Nicaragua.
The Tree: Tree size varies considerably over its range; heights up to 120 ft; diameters 16 to 32 in., occasionally 50 in. Boles are cylindrical, straight, and clear to 50 ft and more.
General Characteristics: Heartwood light reddish brown; distinct from the pale yellowish-brown sapwood. Luster medium; grain straight; texture is somewhat fine and uniform; odor resinous, taste not distinctive; growth rings distinct.
Weight: Basic specific gravity (ovendry weight/green volume) 0.55; air-dry density 41 pcf.
Mechanical Properties: (2-in. standard)
Moisture content Bending strength Modulus of elasticity Maximum crushing strength
(%) (Psi) (1,000 psi) (Psi)
Green (1) 7,970 1,740 3,690
12% 14,870 2,250 7,680
Janka side hardness 580 lb for green material and 910 lb at 12% moisture content. Forest Products Laboratory toughness average for green and dry material is 120 in.-lb. (5/8-in specimen).
Drying and Shrinkage: The wood air-seasons at a fast to moderate rate with a minimum of seasoning defects. Kiln schedule T1 0-D4S is suggested for 4/4 stock and T8-D3S for 8/4. Shrinkage from green to ovendry: radial 4.6%; tangential 7.5%; volumetric 12.3%.
Working Properties: The wood is easy to work with hand and machine tools and is comparable with the southern yellow pines.
Durability: The heartwood is classified as very durable in resistance to attack by white-rot fungus and moderately durable when exposed to a brown rot. The wood does not weather well without the protection of paint or other coatings.
Preservation: Sapwood is permeable; heartwood resistant.
Uses: General purpose construction timber (light and heavy), flooring, box and crate lumber, poles and crossties (treated), and other uses similar to that of the southern yellow pines.
