Is bone stronger than steel?

Bones, as biological components, are subject to self repair, while metals are not. The elastic energy of steel is about the same as bone, but steel has 25 times more energy absorption. A carbon fiber has similar total energy but 10 times more elastic energy than bone. read more

Human bone is about five times stronger than steel by weight. This is mostly due to its cellular structure. The bone’s primary tissue, the osseous, is a hard, honeycombed, spongy composite material that is mainly formed of calcium phosphate, giving the bone its rigidity while remaining lightweight. read more

Bone is extraordinarily strong — ounce for ounce, bone is stronger than steel, since a bar of steel of comparable size would weigh four or five times as much. A cubic inch of bone can in principle bear a load of 19,000 lbs. (8,626 kg) or more — roughly the weight of five standard pickup trucks — making it about four times as strong as concrete. read more
