It occurs from southeast Iowa east to Ohio and southwest Pennsylvania, south to Tennessee and west to northeastern Oklahoma. It is also found in localized areas in southern Ontario in Canada, and New York, northern Georgia, and Mississippi in the United States. Heartwood Color Brown Black Reddish brown Brown Sometimes marketed under the trade name of Red hickory. Sapwood Color White Yellow Pale colored Clearly differentiated from the heartwood Sapwood is often wide and is frequently marketed as as White hickory. Sapwood is sometimes preffered to the heartwood in appearance Grain Even Closed Figure Straight Irregular Wavy Occasionally wavy Irregular grain occasionally Generally straight, but not always Texture Fine Coarse Natural Durability Perishable Susceptible to insect attack Non-durable Non-resistant to termites Non-resistant to powder post beetles Non-resistant to marine borers Very little natural resistance Standing trees/logs vulnerable to attack by forest longhorn or Buprestid beetles Sapwood susceptible to attack by powder post beetles Odor No specific smell or taste Toxicity Some toxic effects Kiln Schedules White handles White handles T8 - D3 (4/4); T6 - D1 (8/4) US Small = T8-D1 Small = T8-D1 Small = T1-D2 Small = T1-D2 Schedule E (4/4) United Kingdom/T8 - D3 (4/4); T6 - D1 (8/4) US Schedule E (4/4) United Kingdom Pink handles Pink handles Large = T8-C1 Large = T8-C1 Large = T1-C2 Large = T1-C2 Drying Defects Distortion Slight twist/warp Severe shrinkage may result Ease of Drying Slowly Dries rapidly with little or no degrade Kiln Drying Rate Naturally dries at a moderate speed Naturally dries slowly Drying rate is fairly rapid to fast Tree Size Tree height is 30-40 m Tree height is 20-30 m Bole length is 20-30 m Bole length is 10-20 m Trunk diameter is 100-150 cm Bark width is 10-15 mm Tree height is 40-50 m Bole length is 0-10 m Large tree, produces the largest hickory nuts.

Density and other related properties of the species are significantly determined by the rate of growth. Wood with wide growth rings is generally high in density and strength. The wood has very good strength properties in relation to its weight, and is well suited for applications where shock resistance is required. Strength properties are slightly superior to those of European beech (Fagus ), but toughness is considerably higher Numerical Data Item Green Dry English Bending Strength 10290 17738 psi Crushing Strength 794 1764 psi Density 42 lbs/ft3 Impact Strength 102 86 inches Maximum Crushing Strength 3842 7840 psi Shearing Strength 2068 psi Stiffness 1313 1852 1000 psi Work to Maximum Load 24 29 inch-lbs/in3 Specific Gravity 0.58 0.63 Radial Shrinkage 8 % Tangential Shrinkage 13 % Volumetric Shrinkage 19 % Item Green Dry Metric Bending Strength 723 1247 kg/cm2 Crushing Strength 55 124 kg/cm2 Density 673 kg/m3 Impact Strength 258 218 cm Maximum Crushing Strength 270 551 kg/cm2 Shearing Strength 145 kg/cm2 Stiffness 92 130 1000 kg/cm2 Work to Maximum Load 1.68 2.03 cm-kg/cm3 Specific Gravity 0.58 0.63 Radial Shrinkage 8 % Tangential Shrinkage 13 % References Boone, R.S., C.J.
