phosphor bronze square tube weight calculator
Enter the dimensions of a phosphor bronze square tube and this works out its volume and weight. C510 spring bronze, used where a copper alloy has to flex repeatedly.
- Weight of one square tube
- 4.997 04
- Volume of one piece
- 564
- Weight per metre of length
- 4.997 04 kg/m
- Density used
- 8860 kg/m3
Show the working
- Outside side = 50
- Wall thickness = 3
- Length = 1000
- Number of pieces = 1
- volume_mm3 = (50^2 - (50 - 2*3)^2) * 1000 = 564 000
- Volume of one piece = 564 000 / 1000 = 564
- Density used = 8860 = 8860
- Weight of one square tube = 564 000 * 8860 / 1e9 = 4.997 04
- Total weight = 4.997 04 * 1 = 4.997 04
- Weight per metre of length = 564 000 / 1000 * 1000 * 8860 / 1e9 = 4.997 04
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- Volume = (side^2 - inner side^2) x length, ignoring the corner radii
- Weight = volume x density, with density = 8860 kg/m3
- One cubic millimetre of a material at 1000 kg/m3 weighs exactly one milligram, so the millimetre-to-kilogram step is a shift of the decimal point rather than a rounded factor.
C510 spring bronze, used where a copper alloy has to flex repeatedly.
Dimensions are nominal. Mill tolerances on thickness, and the corner radii on formed sections, both move the real weight by a percent or two.
Every field takes inches or feet as readily as millimetres: change the unit next to it and the conversion is done exactly before the arithmetic starts.
Frequently asked
What is the density of phosphor bronze?
8860 kg/m3, which is 8.860 g/cm3. C510 spring bronze, used where a copper alloy has to flex repeatedly.
How do you calculate the weight of a phosphor bronze square tube?
Volume = (side^2 - inner side^2) x length, ignoring the corner radii. Multiply the volume by the density of phosphor bronze, 8860 kg/m3, taking care that both are in the same unit system.
Can I enter dimensions in inches?
Yes. Each dimension field has its own unit selector, and inch, foot, millimetre, centimetre and metre entries are all converted exactly before anything is multiplied.
Where the numbers come from
- Densities are nominal room-temperature values for the grade named, drawn from the usual mill and handbook figures.
