General Characteristics: Heartwood is light red to dark red when first cut turning a rich mahogany-like hue on exposure; distinct from the narrow pale sapwood. Texture moderately coarse; grain is commonly interlocked or wavy, sometimes curly; without distinctive odor or taste. Gum veins or pockets are a common defect.

Weight: Basic specific gravity (ovendry weight/green volume) 0.68; air-dry density 54 pcf.

Mechanical Properties: (2-in. standard)
Moisture content Bending strength Modulus of elasticity Maximum crushing strength
(%) (Psi) (1,000 psi) (Psi)
Green (6) 9,880 1,480 5,190
12% 16,200 1,880 8,870
Janka side hardness 1,285 lb for green material and 1,915 lb for dry. Forest Products Laboratory toughness 126 in.-lb for green and 117 in.-lb for dry (5/8- in. specimen).

Drying and Shrinkage: Requires mild drying conditions to avoid checking and warp; collapse is not severe. Air-drying prior to kiln-drying is suggested. Kiln schedule T3-C2 is used for 4/4 stock and T3-C1 for 8/4. Shrinkage green to 12% moisture content: radial 4.6%; tangential 6.6%. Movement in service is rated medium.

Working Properties: Because of high density and irregular grain the wood is difficult to work with hand and machine tools; blunting of cutters is moderate; gluing is good.
