Greenheart
(Chlorocardium rodiei)
Common Name(s): Greenheart
Scientific Name: Chlorocardium rodiei (syn. Ocotea rodiei)
Distribution: Northeastern South America
Tree Size: 75-100 ft (23-30 m) tall, 1.5-2 ft (.5-.6 m) trunk diameter
Average Dried Weight: 63 lbs/ft3 (1,010 kg/m3)
Specific Gravity (Basic, 12% MC): .81, 1.01
Janka Hardness: 2,530 lbf (11,260 N)
Modulus of Rupture: 26,900 lbf/in2 (185.5 MPa)
Elastic Modulus: 3,573,000 lbf/in2 (24.64 GPa)
Crushing Strength: 13,290 lbf/in2 (91.7 MPa)
Shrinkage: Radial: 8.2%, Tangential: 8.9%, Volumetric: 16.5%, T/R Ratio: 1.1
Rot Resistance: Greenheart is rated as very durable, and is also resistant to most insect attacks. It’s also considered to be one of the best-suited woods for use in marine environments, and has good weathering characteristics.
Workability: Generally somewhat difficult to work on account of its density, with a moderate to high blunting effect on cutters. Sections with interlocked grain should be machined with care to avoid grain tearout. Gluing can be difficult in some pieces, and precautions for gluing tropical species should be followed. Turns and finishes well. Responds moderately well to steam-bending.
Sustainability: This wood species is not listed in the CITES Appendices, but is reported by the IUCN as being data deficient. It was formerly listed on the Red List as vulnerable (due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation), but this listing has been disputed by the Guyana Forestry Commission.
Common Uses: Boat building, docks, decking, posts, fishing rods, pool cues, and other turned wood items.
Comments: Greenheart is perhaps the stiffest wood in the world, with an average modulus of elasticity of an astounding 3,716,000 lbf/in2!
