Mockernut hickoryMockernut hickory
Mockernut hickory (Carya tomentosa)

Family: Juglandaceae

Common names: Hickory, Mockernut, Mockernut hickory, White hickory

Distributed in: Canada, United States (North America)

Distribution overview: Mockernut hickory is widely distributed from eastern Massachusetts to Florida west across eastern and central New York and northern Ohio to southeastern Iowa, Missouri, southeastern Kansas, eastern Oklahoma, and eastern Texas. The species occupies upland sites on ridges and hillsides. It is a major component of one forest cover type: Northern Red Oak-Mockernut Hickory-Sweetgum. It is a minor component of 4 other forest types: Post Oak-Black Oak; White Oak-Red Oak-Hickory; Beech-Sugar Maple ; and Swamp Chestnut Oak-Cherrybark Oak.

Common uses: Baseball bats, Cabinetmaking, Charcoal, Decorative veneer, Dining-room furniture, Domestic flooring, Fine furniture, Flooring, Fuelwood, Furniture , Furniture components, Handles, Skis, Sporting Goods, Tool handles, Veneer

Environment profile: Status has not been officially assessed

Tree size: Tree height is 20-30 m

Colors: the heart isRed, Reddish brownand the sapwoodClearly differentiated from the heartwood, Pale colored.The grain isWavy, the textureMediumand the lusterMedium

Natural durability: Susceptible to insect attack, Very little natural resistance

Odor: No specific smell or taste

Kiln Schedules: White handles

Drying Defects: Severe shrinkage may result, Slight twist/warp

Ease of Drying: Dries rapidly with little or no degrade

Blunting Effect: Severe effect

Boring: Excellent (95+ pieces out of 100 will yield excellent results)

Cutting Resistance: Satisfactory sawing properties

Gluing: Difficult to glue

Mortising: Good mortising properties

Nailing: Pre-boring recommended

Planing: Special attention required

Resistance to Impregnation: Wood moderately responsive to treatment

Steam bending: Excellent High bending and crushing strengths, high stiffness and high resistance to shock loads make hickory extremely suitable for steam bending applications

Turning: Good results

Polishing: Good; Staining: Stains well ;

Several species in the genus Carya, including Shellbark (C. laciniosa ), Pignut (C. glabra ), Mockernut (C. tomentosa ), and Shagbark (C. ovata ) are often mixed together and marketed under the trade name Hickory because of very close similarities. Density and other related properties of the species are significantly determined by the rate of growth. Wood with wide growth rings are 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
