Its wood has an average crush strength of 8,140 lb/in 2 (56.1 MPa), which exceeds many hardwoods such as white ash (7,410 lb/in 2) and black maple (6,680 lb/in 2). It is not as strong as black ironwood (9,940 lb/in 2 ), but because its average density is less than half that of ironwood, slash pine has a far greater strength-to-weight ratio.
