Appearance

Color: Heartwood varies from yellow-brown to dark golden brown; turns rich brown under exposure to sunlight. Sapwood is lighter cream color. 
Grain: Straight; coarse, uneven texture. 
Variations Within Species and Grades: Moderate to high color variation.

Properties

Hardness/Janka: 1000; 22% softer than Northern red oak. 
Dimensional Stability: Excellent (change coefficient .00186; 50% more stable than red oak). 
Durability: Strength values are similar to those of American oak.

Workability

Sawing/Machining: Moderate ease in working with hand and machine tools; silica in wood dulls tools quickly: carbide tooling is recommended. 
Sanding: Clogs abrasives; frequent sandpaper changes are required. 
Nailing: Good holding ability. 
Finishing: Natural oils may interfere with adhesion and drying of some finishes. To reduce the wood's tendency to repel finish coats, surface resins may be removed with a solvent that is compatible with the finish to be used. 
Comments: Has an oily feel. Unique in that it does not cause rust or corrosion when in contact with metal. Respiratory and dermatological allergic potential.
