Reference Colour: Red brown
Texture: Coarse
Grain: Straight or interlocked
Interlocked Grain: Slight
Notes: Pink brown to red brown. Bands of light coloured parenchyma tissue give this wood a distinctive figure. Presence of internal stresses and wind shakes (internal fractures in the wood).

Diameter: 60÷90cm
Density @12% MC: 860kg/m³
Janka Hardness: 2640lbf
Crushing Strength @12%MC: 72MPa
Static Bending Strength @12%MC: 128MPa
Longitudinal Modulus of Elasticity E: 20.17GPa
Volumetric Shrinkage Coefficient: 0.65% per %
Total Tangential Shrinkage TS: 7.3%
Total Radial Shrinkage TS: 4.6%
T/R Anisotropy Ratio: 1.6-
Fibre Saturation Point: 23%
Thermal Conductivity: 0.28W/mk
Lower Heating Value: 19180KJ/Kg
Sapwood Thickness: 3÷5cm
Sapwood Demarcation: Clearly demarcated

Resistance to Decay: Class 2 – durable
Resistance to Dry Wood Borers: Class D – durable (sapwood demarcated, risk limited to sapwood)
Resistance to Termites: Class D – durable ANDIRA Cross sections of Andira coriacea
Treatability: Class 3 – poorly treatable
Use Class Covered by Natural Durability: Class 4 – in ground or fresh water contact
Durability Notes: The species Andira coriacea is very resistant to decay (class 1); it naturally covers the use class 5 (wood permanently or regularly submerged in salt water, sea water or brackish water). According to the European standard NF EN 335 of May 2013, performance length might be modified by conditions in which it is used.

Log Buoyancy: Does not float
Log Conservation: Good
Drying Rate: Rapid to normal
Drying Risk of Distortion: Slight risk
Drying Risk of Case Hardening: No known specific risk
Drying Risk of Checking: Slight risk

Blunting Effect: Fairly high
Sawing Tooth: Stellite-tipped
Machining Tool: Tungsten carbide
Suitability for Peeling: Bad
Suitability for Slicing: Good
Sawing Machining Notes: It is difficult to obtain a smooth surface in planing because of the alternate bands of hard and soft wood. Splinters may cause infection.
Assembly Nailing Screwing: Good but pre-boring necessary
Assembly Notes: Tends to split with nailing. High specific gravity: important that gluing be performed in compliance with the code of practice and instructions for the glue used.
End Uses: Turned goods, House framing, Heavy carpentry, Industrial or heavy flooring, Cabinetry (high-end furniture), Sliced veneer, Vehicle or container flooring, Decking, Exterior joinery, Bridges (parts not in contact with water, Interior joinery or ground), Built-in furniture or mobile item, Exterior panelling
