Keledang is non-durable to moderately durable; the average service life in contact with the ground under tropical conditions varies between the species from 1.2-3.3 years. The wood is generally comparatively resistant to termite attack but it is more susceptible to powder-post beetle attack. Wood of ''A. lanceifolius'' showed some resistance to marine borers. The heartwood is very difficult to impregnate, absorbing only about 16 kg/m<sup>3</sup> of preservative using an open tank process.
Keledang wood contains 63-71% holocellulose, 40-44%α-cellulose, 16-25% lignin, 13-14% pentosan and 0.3-1.9% ash. The solubility is 4.6-9.6% in alcohol-benzene, 5.9-13.3% in hot water and 15.6-23.1% in a 1% NaOH solution.

== Silviculture and management ==
''Artocarpus'' requires good soil conditions and can grow rather fast. Partial shade should be provided until the plants are well established (e.g. for ''A. altilis''). In mixed plantations of ''Artocarpus'' (e.g. ''A. heterophyllus'' ), the formation of heavy branches is considerably reduced by partial shading and close spacing (1 m × 1 m). In plantations ''Artocarpus'' soon forms a closed canopy. Natural pruning is satisfactory, as ''Artocarpus'' species are characterized by dense crowns, which also greatly reduces the development of weeds in a plantation. The large amount of litter, which easily decomposes, also reduces weed development. Thinning ''should be done carefully and only when trees have developed a stem branchless for some length (e.g. 8 m). The mortality of different ''Artocarpus'' species over 10 cm diameter in Sarawak was much higher (5-8%) in logged than in undisturbed forest (less than 3%). Trees should not be pruned, as the wounds may cause wood rot and woodboring insects attack the pruned trees. Excellent coppicing is reported from India for ''A. heterophyllus'' and ''A. hirsutus''.
