Wood the growth of the young timber in open stands after the old trees have been removed is more rapid than in trees in a closed forest, and in the manufacture of articles where strength is an important consideration such "second-growth" hardwood material is preferred. This is particularly the case in the choice of hickory for handles and spokes. Here not only strength, but toughness and resilience are important. The results of a series of tests on hickory by the U.S. Forest Service show that: The effect of rate of growth on the qualities of chestnut wood is summarized by the
Neobalanocarpus and sills, tool handles (impact), carving works and other uses where strength and durability are required. On the Malay Peninsula Chengal has been used as the wood of choice for house and boatbuilding. It is sometimes referred to as the "Malaysian Teak". Despite its extreme strength and hardness, Chengal is highly flexible before it is fully cured, making it the ideal wood for plank bending (boatbuilding). It is also highly resistant to rot, fungi and mildew. In addition, Chengal has a relatively low shrinkage ratio, (only inferior to Teak) which makes it excellent for applications where it undergoes periodic changes
