                      2 ft (.6 m) trunk diameter

Average Dried Weight: 52 lbs/ft3 (835 kg/m3)

Specific Gravity (Basic, 12% MC): 0.64, 0.83

Janka Hardness: 1,790 lbf (7,960 N)

Modulus of Rupture: 18,490 lbf/in2 (127.5 MPa)

Elastic Modulus: 2,634,000 lbf/in2 (18.17 GPa)

Crushing Strength: 9,290 lbf/in2 (64.1 MPa)

Shrinkage: Radial: 4.6%, Tangential: 8.6%,

                        Volumetric: 12.3%, T/R Ratio: 1.9

Color/Appearance: Heartwood ranges from golden yellow to darker reddish brown. Parenchyma bands of varying thickness give an subtle, jagged and streaked appearance. (As the parenchyma is lighter in color, the wider the bands, the lighter the overall color of the wood, in general.) Narrow sapwood is a grayish yellow, and is clearly demarcated from the heartwood.

Grain/Texture: Grain is straight to slightly interlocked. Texture is very coarse and porous, with low natural luster.

Rot Resistance: Rated as durable to very durable; moderate insect resistance.

Workability: Generally easy to work, though interlocked grain can cause tearout during surfacing operations. Glues, turns, and finishes well.

Odor: No characteristic odor.

Allergies/Toxicity: Although severe reactions are quite uncommon, partridgewood has been reported to cause skin irritation, as well as hives and coughing. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
