Max. crushing strength = high
Shrinkage, Radial = large
Density (dry weight) = 46-52 lbs/cu. ft.
Bending strength (MOR) = very high
Modulus of Elasticity (stiffness) = high
Hardness (side grain) = medium
Density (dry weight) = 53-60 lbs/cu. ft
Bending strength (MOR) = medium
Bending strength (MOR) = high
Shrinkage, Tangential = fairly large
Modulus of Elasticity (stiffness) = medium
Shrinkage, Tangential = moderate
Shrinkage, Tangential = large
Shrinkage, Radial = fairly large
Shearing strength (parallel to grain) = medium
Modulus of Elasticity (stiffness) = low
Very heavy
Very dense
Toughness-Hammer drop (Impact Strength) = very low
Shrinkage, Volumetric = moderate
Shrinkage, Volumetric = fairly large
Shearing strength (parallel to grain) = low
Max. crushing strength = medium
Hardness (side grain) = hard
Density (dry weight) = 61-67 lbs/cu. ft
Density (dry weight) = 38-45 lbs/cu. ft.
Compression strength (parallel to grain) = very high
It is far superior in strength to either Teak or Hard maple. It has been compared to the North American Hickories (Carya ) in hardness and other strength properties, and is one-and-a-half times as dense as Black walnut (Juglans nigra ).
