Calophyllum is a useful, general-purpose timber. Due to its wide range in density, its mechanical properties can be variable. It is suitable for range of end uses including; furniture and cabinet work, interior joinery, mouldings, architraves and doorjambs, flooring and panelling.
The timbers range in colour from a pale pinkish-brown to pale red-brown to pale red. Quarter-sawn boards produce a pronounced ribbon figure, whilst back sawn material is nicely figured with a fine zigzag pattern.
The timbers can be dried satisfactorily. Quarter-sawn material dries well with little degrade. Back-sawn material has a tendency to cup and twist especially in wide boards.
Calophyllum is popular for a variety of end uses including furniture manufacture and cabinet work as well as for veneer and plywood manufacture.
