Species: eucalyptus marginata
Family: Myrtaceae
Clade: Angiospermae
Description: Eucalyptus marginata (Jarrah) is a large, iconic Australian evergreen tree with distinctive rough, fibrous, reddish-brown bark. It features leathery, lanceolate leaves, creamy-white flowers, and woody gumnuts.

Reference Colour: Red brown
Texture: Medium
Grain: Straight or interlocked
Interlocked Grain: Slight
Notes: Narrow sapwood. Wood red brown to dark brown, sometimes interlocked, wavy or curly.

Diameter: 60÷120cm
Density @12% MC: 820kg/m³
Janka Hardness: 2790lbf
Crushing Strength @12%MC: 81MPa
Static Bending Strength @12%MC: 101MPa
Longitudinal Modulus of Elasticity E: 20.09GPa
Volumetric Shrinkage Coefficient: 0.54% per %
Total Tangential Shrinkage TS: 10.5%

T/R Anisotropy Ratio: 1.6-
Fibre Saturation Point: 34%
Thermal Conductivity: 0.27W/mk
Sapwood Thickness: 3÷6cm
Sapwood Demarcation: Clearly demarcated

Resistance to Decay: Class 1 – very durable
Resistance to Dry Wood Borers: Class D – durable (sapwood demarcated, risk limited to sapwood)
Resistance to Termites: Class M – moderately durable Atlas of Tropical Timber Species JARRAH Cross sections of Eucalyptus marginata
Treatability: Class 4 – non-treatable
Use Class Covered by Natural Durability: Class 4 – in ground or fresh water contact
Durability Notes: This species is listed in the NF EN 350 standard. According to the European standard NF EN 335 of May 2013, performance length might be modified by conditions in which it is used. Resistance to termites varies widely depending on the origin of the wood (e.g. natural forest or plantation).

Log Buoyancy: Does not float
Log Conservation: Good
Drying Rate: Slow
Drying Risk of Distortion: High risk
Drying Risk of Case Hardening: No known specific risk
Drying Risk of Checking: High risk

Blunting Effect: Fairly high
Sawing Tooth: Stellite-tipped
Machining Tool: Tungsten carbide
Suitability for Peeling: Not recommended or without interest
Suitability for Slicing: Not recommended or without interest
Sawing Machining Notes: Sawing and machining difficulties in the presence of interlocked grain. Reducing the cutting angle to 15° is recommended to avoid tearing.
Assembly Nailing Screwing: Good but pre-boring necessary
Assembly Notes: High specific gravity: important that gluing be performed in compliance with the code of practice and instructions for the glue used.
