Density (dry weight) = 46-52 lbs/cu. ft. 1 Max. crushing strength = medium Bending strength (MOR) = medium Shearing strength (parallel to grain) = medium Density (dry weight) = 38-45 lbs/cu. ft. Modulus of Elasticity (stiffness) = low Shrinkage, Radial = large Shrinkage, Tangential = large Max. crushing strength = high Toughness (total work) = medium Toughness (total work) = high Hardness (side grain) = medium Toughness-Hammer drop (Impact Strength) = high Shrinkage, Tangential = fairly large Shearing strength (parallel to grain) = low Resists denting and marring Modulus of Elasticity (stiffness) = medium Heavy Compression strength (parallel to grain) = high Bending strength (MOR) = very high Bending strength (MOR) = high
Bending strength in the air-dry condition (about 12 percent moisture content) is very high. Maximum crushing strength, or compression strength parallel to grain, is also high. The wood is fairly hard, resisting wear, denting, and marring fairly well. Weight is very high, and it has high density. Strength properties of European hornbeam are comparable to those of European beech, and the timber is considered a suitable alternative to Maple (Acer ) for light industrial flooring
