Weight per metre of length: 5.150 52 kg/m
Density used: 7530 kg/m3

Outside width = 80
Outside height = 40
Wall thickness = 3
Length = 1000
Number of pieces = 1
volume_mm3 = (80*40 - (80 - 2*3)*(40 - 2*3)) * 1000 = 684 000
Volume of one piece = 684 000 / 1000 = 684
Density used = 7530 = 7530
Weight of one rectangular tube = 684 000 * 7530 / 1e9 = 5.150 52
Total weight = 5.150 52 * 1 = 5.150 52
Weight per metre of length = 684 000 / 1000 * 1000 * 7530 / 1e9 = 5.150 52

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 = (outer area - inner area) x length, ignoring the corner radii
Weight = volume x density, with density = 7530 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.

C954, strong and unusually corrosion-resistant for a copper alloy.

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 aluminium bronze?

7530 kg/m3, which is 7.530 g/cm3. C954, strong and unusually corrosion-resistant for a copper alloy.

How do you calculate the weight of a aluminium bronze rectangular tube?

Volume = (outer area - inner area) x length, ignoring the corner radii. Multiply the volume by the density of aluminium bronze, 7530 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.
