It was often used as railroad ties, mine pit materials, farm tools, high-grade charcoal, etc. However, with unruly grain patterns, it is prone to cracks and difficult to process. After thermal modification at 150°C, the dimensional stability and durability of acacia is improved, with sapwood and heartwood showing better color and grain patterns. The modified wood greatly increased the value of domestic timber, as it not only can be applied to home decoration and furniture but also can be used for high-quality musical instruments, such as erhu, ukulele, guitar, stereo, and cajón.
