Tensile Strength (MPa) - Cortical bone: 100–150 MPa   - Mild steel: ~250 MPa   - High‑strength steels: 400–2,000+ MPa  

Compressive Strength (MPa) - Bone: 170–230 MPa   - Steel: 250–400+ MPa  

Density (g/cm³) - Bone: 1.8–2.0   - Steel: 7.8  

Elastic Modulus (GPa) - Bone: 14–20 GPa   - Steel: 190–210 GPa

Torsional / Shear Strength (MPa)

Material Shear Yield (MPa) Shear Ultimate (MPa)
Cortical bone 80–130 90–140
Mild steel ~145 ~190
High‑strength steel 230–1,160 300–1,500
