The sapwood is liable to fungi and powder-post beetles and should be removed before the wood is processed. The resistance to wood-rotting fungi is due to the presence of natural compounds such as isookanin and okanin[

It is difficult to obtain a smooth finish because of the interlocked grain; planing shows best results at a cutting angle of 15°; the wood holds screws and nails well, but pre-boring is needed; the gluing, staining, polishing and painting properties are satisfactory, but for optimal polishing effect the use of a filler is required; turning gives good results. The wood is not suitable for veneer or plywood production[
