Working and Finishing Properties
In its green state, It is an easy wood to convert and resaw. However, it becomes harder and tougher when seasoned. It works well by hand machines and finishes to a good surface. Its working quality index based on quality of worked surface and ease of working is 84 compared to 100 for teak.
Timber
The wood is widely used for construction as posts, rafters, beams and in door frames. It is one of the most favoured timbers for all types of agricultural implements like ploughs, harrows, crushers and rice pounders, and is extensively used in card building, for yokes, shafts, wheels and body work. Babul wood is also recommended for certain types of sports and athletic goods like clubs, wall bars, parallel bars, etc..

Fuelwood- and charcoal. Its charcoal is considered to be superior to charcoal from other species.
