Hardwood Timber Flooring Species: Australian Beech

Timber Species: Australian Beech - Lophozonia Cunninghamii

Also known as myrtle beech or Tasmanian myrtle, Australian beech grows mainly in eastern Victoria and Tasmania. While it’s got no real relation to European myrtle, early timber workers encountering the tree in the region gave it its name for the similarity in its characteristics.

Australian beech grows typically between 30 and 40 meters. An evergreen varietal, the tree is quite robust and hardy, with dark green leaves that shine a brilliant red, orange, or pink with new growth in the spring. Often found springing up in highly volcanic and acidic soils, the Australian beech has long been a favorite pick for cabinetry thanks to its tough, close, hard grain.

Australian beech produces beautiful hues, ranging from pale brown to gold, resulting in undertones that include slight pink or even light cream. Beech flooring is typically a blend of lighter hardwoods, with grain patterns that can range from fiddle-backed and wavy, interlocked, or straight. Highly appealing for furniture, joinery, and veneers thanks to its burls, this attractive timber is often used for commercial purposes thanks to its creamy, warm, pink tones.

Australian beech features a Janka hardness rating, dependent on the specific timber, of typically around 7.5. Its pH level is around 4.5, making it moderately acidic. Dry density for Australian beech ranges between 780-900 kg/m³. Again, as individual specimens can vary to some degree in not just grain pattern and color but density, hardness, and acidity, specific example ranges are to be expected but not guaranteed. Suited to both natural timber flooring and parquetry, this wood is an attractive choice for many building and decorating projects.

Dry Density: range 780-900 kg/m³

Janka Hardness: 7.5 kN

These properties are only a guide, as timber is a natural product there will be variations within any species. The Janka Dry Hardness rating measures the hardness of the wood. The higher the number the harder the wood.
