Common Name(s): Bloodwood, Satine
Scientific Name: Brosimum rubescens (syn. B. paraense)
Distribution: Tropical South America
Tree Size: 80-150 ft (25-45 m) tall, 4-7 ft (120-210 m) trunk diameter

Modulus of Rupture: 25,290 lbf/in2 (174.4 MPa)
Elastic Modulus: 3,013,000 lbf/in2 (20.78 GPa)
Crushing Strength: 14,310 lbf/in2 (98.7 MPa)

Color/Appearance: Heartwood is a bright, vivid red. Color can darken to a darker brownish red over time with exposure to light. Applying a thick protective finish, and keeping the wood out of direct sunlight can help slow this color shift. Well defined sapwood is a pale yellowish color, though given the typically large trunk diameters, it’s seldom seen or included in imported lumber.
Grain/Texture: Grain is usually straight or slightly interlocked. Has a fine texture with good natural luster, and is also somewhat chatoyant.
Endgrain: Diffuse-porous; large pores, few; solitary and radial multiples of 2-3; tyloses and other mineral deposits common; parenchyma winged and confluent; narrow to medium rays, normal spacing.
Rot Resistance: Reported to be very durable, and resistant to most insect attacks.
Workability: Bloodwood is extremely dense, and has a pronounced blunting effect on cutters. The wood tends to be brittle and can splinter easily while being worked. Those persistent enough to bear with the difficulties of working with Bloodwood to the finishing stage are rewarded with an exceptional and lustrous red surface.
