Physical and mechanical properties of plantation-grown Acacia auriculiformis of three different ages

Summary We assessed the physical and mechanical properties of timber of plantation-grown 8-, 12- and 13-y-old trees of Acacia auriculiformis A.Cunn. ex Benth. from Sirsi, Karnataka, India. The timber of the 13-y-old trees was dense, very strong, moderately tough, stable in service and hard, and it compared favourably with teak in several properties. The results suggest that it can be used for tool handles, oars, paddles, packing cases, ammunition boxes, etc. It was also found suitable for the rural construction industry where timbers of small diameter can be used. If trees are allowed to grow older to attain greater size the range of potential uses will increase.
