Scientific Name: Robinia pseudoacacia
Distribution: Central-eastern United States (also widely naturalized in many temperate areas worldwide)
Tree Size: 20-30 m tall, trunk diameter: 0,6 - 1 m
Average Dried Weight: 770 kg/m3 (MC 12%)
Shrinkage: Radial: 4.6%, Tangential: 7.2%,Volumetric: 10.2%
Color/Appearance: Color can range from a pale greenish-yellow to a darker brown. Tends to darken to a russet brown with age. Can be confused with osage orange and honey locust in some instances.
Grain/Texture: Grain is usually straight, with a medium texture.
Rot Resistance: Rated as very durable, with good weathering characteristics. Frequently used as fence posts for its outdoor longevity.
Workability: Overall working characteristics for black locust are mixed: although the grain is usually straight, its high density and hardness can make it more difficult to machine when compared to other domestic hardwoods. Black locust also has a moderate blunting effect on cutting edges. Responds very well to both lathe turning and steam bending; glues and finishes well.
Common Uses: Fence posts, boatbuilding, flooring, furniture, mine timbers, railroad ties, turned objects, and veneer.
Comments: Black locust is a very hard and strong wood, competing with hickory (Carya genus) as the strongest and stiffest domestic timber: but with more stability and rot resistance.
