White locust wood is native to South America, more specifically in some areas of Argentina, Paraguay and Chile. It is known for its versatility and resistance, and is even suitable for outdoor use.

Its scientific name is Prosopis alba, and in Anglo-Saxon countries it is known as Algarrobo blanco.

There is another type of carob wood, black carob. This one, as its name implies, is darker and would originate mainly in Colombia.

White locust beans are not yet considered an endangered species. However, if current exploitation levels are maintained, it is very possible that it will be incorporated as a vulnerable species into the Convention on International Trade in Endangered Species (CITES).


Color: The hard has colors that range from yellow to light brown, which darken with time. The sapwood, which tends to be narrow, is pale yellow.

Fiber: Straight and sometimes interlaced.

Grain: Medium.

Density: It has an approximate density of 785 kg / m³ at 12% humidity. Therefore, it is a heavy wood.

Toughness: Difficult.

Durability: It has excellent performance outdoors. Even in direct contact with the ground. So it is sometimes used to make poles or fences. Durable against fungi and insects.

Dimensional stability:

  • Volumetric contraction coefficient: –

Mechanical properties:

  • Compressive strength: 600 kg / cmtwo
  • Resistance to static bending: – kg / cmtwo
  • Modulus of elasticity: 62,000 kg / cmtwo

Workability: It depends a lot on the quality of the wood. Although as a general rule it is not a bad wood to work with, in the case of interlaced fiber the work is complicated.

  • Sawn. Problems in cases of interlaced fiber.
  • Drying. Slow Some problems due to internal stresses.
  • Brushed. Problems derived from interlaced fiber.
  • Glued. Smoothly.
  • Nailed and screwed. Due to its hardness, pre-drilling is required.
  • Finish. Smoothly.
