Garapa: density, weight and properties
Apuleia leiocarpa
Garapa (Apuleia leiocarpa) averages 790 kg/m³ at 12% moisture content, according to CIRAD’s Tropix database. The figures below are averages for clear, mature wood; individual boards vary with origin, growth and moisture.

Weight at 12% moisture content
Volume × 790 kg/m³, the same calculation as the weight calculator. Green or wet wood weighs considerably more.
| Piece | Size | Weight |
|---|---|---|
| 1 cubic metre | 1,000 × 1,000 × 1,000 mm | 790 kg |
| 1 board foot | 12 × 12 × 1 in | 1.86 kg |
| 1×4 board, 8 ft | 3/4 × 3 1/2 in actual × 8 ft | 3.26 kg |
| 1×6 board, 8 ft | 3/4 × 5 1/2 in actual × 8 ft | 5.13 kg |
| 2×4 board, 8 ft | 1 1/2 × 3 1/2 in actual × 8 ft | 6.52 kg |
| 2×6 board, 10 ft | 1 1/2 × 5 1/2 in actual × 10 ft | 12.8 kg |
Movement across the width
How much a board 11 1/4 in (286 mm) wide changes when its moisture content moves by a few percentage points. The estimate uses the total shrinkage above and a linear relation below the fibre saturation point of 22% (Wood Handbook Eq. 4-9). Flat-sawn boards move with tangential shrinkage, quartersawn boards with radial shrinkage.
| Moisture change | Flat-sawn | Quartersawn |
|---|---|---|
| 3 percentage points | 2.9 mm (0.115 in) | 1.6 mm (0.064 in) |
| 6 percentage points | 5.8 mm (0.23 in) | 3.3 mm (0.129 in) |

Natural durability
Durability of the heartwood against wood-decay fungi: class 3 on the EN 350 scale from 1 (very durable) to 5 (not durable), as reported by Tropix. The rating applies to heartwood only.
Working and finishing
High silica content blunts tools, and with its irregular interlocked grain Tropix advises reducing the feed speed and cutting angles when machining. Finishing is easy, but a pore filler is recommended. Its natural durability is very variable.
Typical uses
