Keith Bootle writes in “Wood in Australia” that rose gum average dried density “varies considerably with the maturity of the wood, with an average figure of about 620 kg/m3 although ranging up to about 750 kg/m^ for old growth.”. Eucalyptus conjures images of Australia, whose old-growth forests primarily consist of this large, strong tree. Conversely, woods with low specific gravity don't make good choices for furniture and are more difficult to create nice, strong joints with. Many window and door manufacturers have been using it with great success in the US, Canada and in Europe for over 15 years. Paler sapwood is sometimes indistinct from heartwood. Copyright ©

520-745-8301. Scientific Name: Eucalyptus urograndis (Eucalyptus grandis x E. urophylla hybrid). Distribution: Grown on plantations in Brazil. Glues, stains, and finishes well. The trouble with this number is that the specific gravity of a wood changes with its moisture content. 2. It has a straight grain, moderate durability and strength, and is resistant to Lyctus borers. Harder woods create good, solid long-lasting joinery in furniture. Pricing/Availability: Occasionally exported to North America. Rose gum (Eucalyptus grandis) is a large, fast growing hardwood timber.When grown in a favourable environment, rose gum is one of the most productive plantation eucalypts.

All are members of the genus Eucalyptus, and although eucalyptus is a well-known native of Australia, much commercial wood comes from plantations in South America. Specific gravity is the ratio of the density of wood to the density of water. Common Name(s): Rose Gum, Flooded Gum. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information. We've also compared the number to that of red oak, as red oak is the most commonly used hardwood in North America. Wood from these trees is generally flexible and easy with which to work. Most of the time, the higher the specific gravity, the more abuse your tools take. Eucalyptus Grandis 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) Comments: Rose Gum is a common plantation species, though a hybrid species marketed as Lyptus® is grown in Brazil: Rose Gum is bred with an Indonesian species (Eucalyptus urophylla) to help increase disease and insect resistance. Grain/Texture: Usually straight-grained or shallowly interlocked, with a uniform medium to coarse texture. Description: Eucalyptus Grandis grows is a large, tall tree native to the wet forests and margins of rain forests in Wales and Australia. The name Grandis means large, which refers to the tree’s size. It is a very tall forest tree, reaching 45 to 55 metres in height, with a trunk of between one and two metres in diameter. Within Australia, plantations exist in northern New South Wales, where seedlings have put on 7 metres (23 feet) of growth in their first year.

Workability: Fairly easy to work with both hand and machine tools, though Rose Gum experiences a large amount of shrinkage when drying, and a relatively large amount of movement in service. Scientific Name: Eucalyptus grandis. Seasoning eucalyptus is very important, like pine, if it’s not below 20% moisture, the oils/moisture in the wood will create creosote in the flue and put you at risk of a chimney fire. This study analyzed the effectiveness of the impulse excitation technique (IET) to characterize the stiffness of 10-year-old Eucalyptus grandis wood at three different heights of 3 m, 6 m, and 9 m from the bottom (height A, B, and C, respectively).

We display the specific gravity for each of our woods using it's kiln-dried measurement (instead of the non-dried measurement). As the site is interested in reflecting AVERAGE values and not outliers, my number of 640 kg/m3 is actually slightly higher than Bootle’s listed average of 620 kg/m3. We'll even re-share with our community! You might want to look into a moisture meter to test the moisture content before you burn it. Prices are moderate for an imported hardwood. Wood is a natural material with great variability in its mechanical properties. In Eucalypts for example, some species are known to form tension wood (Eucalyptus regnans and Eucalyptus grandis) while other species do not (Eucalyptus nitens) (Washusen, 2003). Stores
