Weight of Metal vs. Density of Metal
Weight is the heaviness of a particular thing; the weight of an object is the measurement of the force acting on the object due to gravity. Since weight is a property inherent in a specific object, it doesn’t strictly make sense to talk about the weight of a substance (like iron) in the abstract. To state the weight of something, there needs to be an object to state the weight of.
Density can be loosely defined as the weight per unit of volume, so the objects that we’re stating the weight of in the table below can be thought of as cubes of metal the size of the given unit of volume (one foot cubed, one inch cubed, one meter cubed, and one centimeter cubed).
For example: “500 pounds” is a weight value. “500 pounds per cubic foot” is a density value.
So, you can see that the values given in our table are technically metal densities, since we express the values as weight/unit of volume.
We called this web page “Weight of Metals and Alloys” instead of “Densities of Metals and Alloys” to make it easier for people to find what they were looking for on the internet. A lot of people search for “weight of metal” when they actually mean “density of metal”.
About This Metal Weight Chart
The following table provides typical values for the weights (densities) of elemental metals and alloys with industrial applications.
Generally, the weight of metals (or density of metals, to be precise) that we list were calculated from the values provided by sources such as the Encyclopedia Britannica or the National Institute of Standards and Technology that we consider to be reliably authoritative.
The values for the weights of alloys were taken from manufacturer technical data sheets and are the actual weights of specific, representative products.
In all cases, the weight of metals we provide are meant to provide a general idea of what the various metals weigh, and should not be used if precise values are needed for critical engineering calculations.
When precision is necessary, always refer to the data sheets of the actual, specific product you intend to use, or contact the technical department of the product manufacturer or material provider.
All of the metal weight values we show are the density values for the metals at room temperature.
