Relative Hardness (ranked by the Janka hardness rating): 1450
12% harder than Northern Red Oak.

Relative Stability (ranked by dimensional change coefficient): .00353
4% more stable than Northern Red Oak.

Color: Heartwood is creamy white to light reddish brown; sapwood is pale to creamy white.

Durability: Dense, strong, tough, stiff, excellent shock resistance, markedly wear resistant.

Workability: Density makes it very difficult to saw; sands satisfactorily. Nailing: fair resistance to splitting; good holding ability. Finishing: takes neutral finish well; does not stain uniformly.

Flame Spread Index (ASTM-E84): 104

Smoke Developed Index (S.D.I): 157
