Metals and Alloys - Bulk Modulus Elasticity

The Bulk Modulus - resistance to uniform compression - for some common metals and alloys.

The Bulk Modulus Elasticity - or Volume Modulus - is a measure of the substance's resistance to uniform compression.

Bulk Modulus of Elasticity is the ratio of stress to the change in volume in a material subjected to axial loading.

Typical values of bulk modulus for some metals and alloys are indicated below. Note that the values may vary widely.

Metals and Alloys - Bulk Modulus Elasticity

- K -
(106 psi)(GPa)
Aluminum, various alloys 9.9 - 10.2 68 - 70
Boron Carbide (B4) 29 - 34.8 200 - 240
Brass, 70-30 15.7 108
Brass, cast 16.8 116
Concrete 0.87 - 4.1 6 - 28
Copper 17.9 123
Diamond (carbon) 80 - 93 550 - 640
Iron, cast 8.4 - 15.5 58 - 107
Iron, malleable 17.2 119
Magnesium alloy 4.8 33.1
Monel metal 22.5 155
Phosphor bronze 16.3 112
Silver 13.9 - 15.4 96 - 106
Stainless Steels (18-8) 23.6 163
Steel, cast 20.2 139
Steel, cold rolled 23.1 159
Steel, various 22.6 - 24.0 156 - 165
Tin 6.1 - 8.4 42 - 60
Tungsten 44.5 - 15.5 307 - 314
  • 1 GPa = 109 Pa (N/m2)
  • 1 GPa = 0.145 psi

Stainless steel with Bulk Modulus 163 109 Pa is approximate 80 times harder to compress than water with Bulk Modulus 2.15 109 Pa.

Bulk Modulus is related to Modulus of Elasticity and Poisson's Ratio as

K = E / 3 (1 - 2 r)                                                (1)

where

K = Bulk Modulus (Pa (N/m2), psi (lbf/in2)

E = Modulus of Elasticity (Pa (N/m2), psi (lbf/in2)

r = Poisson's Ratio
