A Chart of the Density of Wood Species
I have included several familiar woods that probably will never be used in banjo making for the sake of comparison. I have also included domestic and exotic woods that could be or have been used for banjo making. The species in bold are ones I have used for making rims.
The following is a wood density chart compiled from several different sources. In the metric system "kg/cu.m" is kilograms per cubic meter. A cubic meter of water is 1,000 kg. Therefore woods that are less than 1,000 kg/cu.m will float whereas over 1,000 kg/cu.m wood will sink.
Species | kg/cu.m | Balsa | 170 | Pine | 360 | Red Cedar | 380 | Poplar | 420 | Willow | 420 | Redwood | 450 | Sitka Spruce | 450 | Cherry | 510 | Cypress | 510 | Soft Maple | 540 | Honduras Mahogany | 550 | Walnut | 560 | Sycamore | 590 | Elm | 600 | Beech | 640 | African Mahogany | 650 | Oak | 650 | Ash | 670 | Birch | 670 | Hard Maple | 710 | Padauk | 730 | Purple Heart | 740 | Teak | 750 | Bolivian Rosewood | 760 | East Indian Rosewood | 780 | Brazillian Rosewood | 800 | Ebony | 960 | African Blackwood | 1100 | Cocobolo | 1150 | Lignum Vitae | 1280 | Iron Wood | 1300 |
