Appearance
COLOR: Pecan heartwood is reddish brown with
dark brown stripes; sapwood is white or creamy white with pinkish tones.
Hickory heartwood is tan or reddish; sapwood is white to cream, with fine
brown lines.
GRAIN: Pecan is open, occasionally wavy or irregular. Hickory is
closed, with moderate definition; somewhat rough-textured.
VARIATIONS WITHIN SPECIES AND GRADES: In
both hickory and pecan, there are often pronounced differ-entiations in
color between spring wood and summer wood. In pecan, sapwood is usually
graded higher than darker heartwood. Pecan and hickory are traditionally
mixed by flooring mills.
Properties
HARDNESS (JANKA): 1820; 41% harder than Northern
red oak. Pecan is slightly softer than true hickories.
DIMENSIONAL STABILITY: Pecan, average (change
coefficient .00315; 15% more stable than red oak). Hickory, below average
(change coefficient .00411; 11% less stable than red oak).
DURABILITY: Combination of strength, hardness,
toughness and stiffness found in no other commercial wood; exceedingly
high in shock resistance.
Workability
SAWING/MACHINING: Hickory species’ density
makes it difficult to season, machine and work with hand tools.
SANDING: Difficult to sand because of density, and because light
color makes sander marks show more than on darker woods.
NAILING: Good holding ability; prone to splitting.
FINISHING: No known problems.
