Metal Density Chart
lb/in³ · lb/ft³ · g/cm³ · kg/m³
Densities of the metals fabricators actually buy — carbon and stainless steel, aluminum,
copper alloys, and titanium — in shop units and metric. Every stock weight is just
area × length × density; the
free estimator does that math for plate, bar, tube, angle, and pipe using
these same values. For what these metals trade at today, see the
daily metal prices.

|---|
| Zinc | 0.258 | 446 | 7.14 | 7140 |

Nominal handbook values; actual density varies slightly by heat and temper. lb/ft³ and
g/cm³ are the standard published figures, so small rounding differences between columns
are expected.
