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; medium pores arranged in diagonal rows; exclusively solitary; tyloses occasionally present; growth rings indistinct; rays usually not visible without lens; 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.

    I had some beautiful deep red 8/4 lyptus that I used for the base of my workbench. Machined well and finished gorgeously… but LOTS of splinters in my hands while I was working it. Wouldn’t hesitate to use it for some furniture if I got hold of some more!

  • alpha pud

    good stuff, chiped the ends and nailed it to my ceiling, been there ever since.

  • James

    Used it for interior trim. It works well and finishes beautifully.I wonder if it is stable enough to make up large table tops?

  • Pete

    I just put in a 54″x72″ laminated Counter top of Lyptus. It turned out beautifully. Routed the ends which had no tear out or chips. Machined really easy. It is a hard wood and very heavy. I’ve had a very minimal amount of movement in the top. After clear staining to preserve the rich pinkish color, I finished it off with two coats of “Good Stuff” a non-toxic finisher which food can be placed on. Tons of small splinters when working it though. I’ve seen it used as a restaurant counter top with little if any problems.

    Does anyone know the worth of such a tree
    directly on the plantation ?
    I want to grow Eukalyptus-Hybrid-Clones Grandis-Camadulensis

    thanks

  • Milton Bertin

    It is necessary to apply a sealer ???

  • bobbg

    Will it Rot outside I’d like to make a door for a storm window for outside use, I can stain and seal it. It would probably look better anyway. A nice deep reddish brown would look nice.

      I wouldn’t trust it outdoors unprotected. However, I’ve heard that rot resistance varies depending on the growing conditions of the tree, and generally the boards that are naturally a very dark red have better resistance than boards that are naturally a lighter pink color.
