Measure a metal object, enter its dimensions and weight, calculate its approximate density, and compare the result with common metals and alloys.
Can I identify a metal using only density? Density can narrow the possibilities, but it normally cannot prove the exact metal or alloy. Several different alloys can have similar densities.
What is the best shape for density measurement? A simple solid bar, cylinder or block with accurately measurable dimensions is convenient because its volume can be calculated directly.
Can I calculate density for pipe or tubing? Yes. Select the round tube or square/rectangular tube option and enter the outer and inner dimensions.
Why does my steel measurement not equal 7.85 g/cm³? 7.85 g/cm³ is a common reference for carbon steel, not a universal value for every steel alloy. Measurement errors, coatings, hollow sections and alloy composition can also cause differences.
Can this distinguish copper from brass? Density can help because copper and brass occupy different density ranges, but brass composition varies and measurement accuracy is important.
Can this identify precious metals? Density testing can be one screening method for some precious-metal objects, but it should not be treated as definitive authentication because plating, cavities and alloy composition can produce misleading results.
What if the object is irregular? Use a suitable volume-measurement method or approximate the object using multiple geometric sections. The calculator is most reliable when the volume is known accurately.
What does g/cm³ mean? It means grams per cubic centimetre and is a common unit for comparing the density of metals.
