Rot Resistance
Mora is rated as durable to very durable, and also has good resistance to insect attacks.
Pieces with interlocked grain can be difficult to work, frequently resulting in tearout during machining operations. Mora also has a pronounced blunting effect on cutting edges.
Mora can have an unpleasant and sour odor while being worked.
Mora has been reported to cause respiratory irritation.
Mora is used within its native range, and is only occasionally exported. When available, prices should be moderate for an imported hardwood.
This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
Common Uses
Flooring, boatbuilding, heavy (exterior) construction, and turned objects.
Not to be confused with a striped Guatemalan wood that is also sometimes marketed as “Mora,” which is almost universally mislabeled as Maclura tinctoria. Mora excelsa can be distinguished by a more uniform and consistent color, as well as a coarser texture and an unpleasant sour odor when being worked.
