Common Name(s): Lyptus®

Scientific Name: Eucalyptus urograndis (Eucalyptus grandis x E. urophylla hybrid)

Distribution: Grown on plantations in Brazil

Tree Size: 65-100 ft (20-30 m) tall, 3-4 ft (1-1.2 m) trunk diameter

Average Dried Weight: 53 lbs/ft3 (850 kg/m3)

Specific Gravity (Basic, 12% MC): .60, .85

Janka Hardness: 1,420 lbf (6,330 N)

Modulus of Rupture: 17,110 lbf/in2 (118.0 MPa)

Elastic Modulus: 2,049,000 lbf/in2 (14.13 GPa)

Crushing Strength: 8,640 lbf/in2 (59.6 MPa)

Shrinkage: Radial: 8.2%, Tangential: 12.8%, Volumetric: 21.0%, T/R Ratio: 1.6

Color/Appearance: Color ranges from a lighter salmon pink to a darker brownish red. Appearance has been likened to both Black Cherry and Honduran Mahogany. Color tends to deepen with age.

Grain/Texture: Has a medium texture and small to medium sized open pores. The grain tends to be straight and even. Also, since the wood is grown and pruned on a plantation, there tends to be few knots or other abnormal grain patterns.

Endgrain: Diffuse-porous; large to very large pores arranged in diagonal rows, few; exclusively solitary; tyloses occasionally present; growth rings indistinct; narrow rays usually not visible without lens, fairly close spacing; parenchyma vasicentric.

Rot Resistance: Mixed reports, with most sources rating the heartwood as moderately durable in regard to decay resistance, though it is susceptible to insect attack.

Workability: Generally easy to work, though it can burn easily. Glues, stains, and finishes well.

Odor: No characteristic odor.

Allergies/Toxicity: Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Lyptus®. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Should be reasonably priced, especially  for an import. (This is most likely due to the source of the wood: which is exclusively grown on plantations.)

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Flooring, lumber, interior millwork, cabinetry, plywood, and turned objects.

Comments: Lyptus® is merely a trade name, which is a registered trademark owned by the Brazilian company Fibria. The Lyptus® brand is marketed in the United States by Weyerhaeuser. The actual tree species, which is grown on Brazilian plantations owned by Fibria, is a Eucalyptus hybrid of Eucalyptus grandis and E. urophylla.

In terms of mechanical/physical characteristics, Lyptus® has a very high shrinkage rate, and is likely to experience a fair amount of seasonal movement. The wood is relatively hard, heavy, and strong, though as a general rule, the paler pinkish brown boards tend to be less dense, while the darker reddish brown boards tend to be heavier and harder.
