    Steel is not heavier than copper. Copper has a density of 8.96 grams per cubic centimeter. Iron, steel’s primary constituent, has a density of 7.87 grams per cubic centimeter.

      Steel is heavier than copper since is an alloy and can bare more fatigue since it is strong while copper is malleable hence can made to make any shape this show that steel denser than copper

        Ryan is correct, copper has a higher density than steel.
        For the same volume, it weights more. The posted article is wrong in this regard. Please correct.

        Copper is heavier than steel.

        Density is mass/volume, a cube of copper will have a greater mass than an equal size cube of steel and is therefore more dense.

        Jeb is correct, Job is not.

        In addition, Google must be using this article in there main headline because now google is saying steel is heavier than copper. Do a main search on google, “Is steel heavier than copper”, this is the first article that shows up and states, “steel is heaver than copper”, INCORRECT! This article needs retracted.

        Prime example, don’t believe everything you read.

    Good article written and I agree with most, but unfortunately incorrect on that last part. Copper is more dense than Steel. Strength and hardness does not matter between the two, it’s not part of the calculation. If you have the same volume for both steel and copper, copper is going to weight more.

    Density x Volume = Mass (weight)

    Using a 1.00 in³ cube of steel and copper here is your mass for both.
    (Density: Steel = 0.283 lb/in³, Copper = 0.324 lb/in³)

    Steel Mass = 0.283 x 1.00 = 0.283 lb.
    Copper Mass = 0.324 x 1.00 = 0.324 lb.

    Steel was used by the U.S. In 1943 the United States was fully involved in World War 2 and steel was used for coins to make more Cooper available to the war effort. At that point in history the U.S. had not yet become the penny pincher of contemporary Government (pun intended).
