Mahogany

Swietenia Macrophylla King Fm. Meliaceae

Mahogany is the best wood for joinery / cabinetmaking / carpentry.
Mahogany is easy to work material; durable, resistant to termites and woodworms. Excellent for brushing, turning, drilling and molding.

Simple to glue, fix nails and screws well; good polishing capabilities. It produces wide tables due to its large trunk volume.

Mahogany Uses

Chairs, tables, cabinets, doors, interior decoration, coffins, handicrafts, sculpture, lathe, navigation instruments, church benches, musical instruments (pianos, acoustic guitars, mandolins, drums, electric guitars).

The Mahogany has a great resistance to moisture and putrefaction appropriate to build boats, urban ornate tree and for shading in parks, contains usable tannin.
