Aluminum 5052-H32 Angle (L Section) Weight
Mass per metre and per foot for aluminum 5052-h32 angle (l section) at 2,680 kg/m³ (ASTM B209 (H32 temper)). Every figure is for the section as drawn. A 6 m length of this size weighs 7.6 kg (17.1 lb per 20 ft).
At the reference dimensions (a = 50 mm, b = 50 mm, t = 5 mm) this section has a cross-sectional area of 475.0 mm², giving 1.273 kg/m (0.855 lb/ft). Against carbon steel's 7,850 kg/m³ that is -65.9 % — the same section in steel would be 3.729 kg/m.
Angle (L Section) — formula and derivation
Area of a angle (l section)
A = t · (a + b − t)
A = t × (a + b − t), where a and b are the two leg lengths and t the thickness. Equal-leg angles set a = b, giving A = t(2a − t)
Worked through with the default dimensions:
A = t × (a + b − t)A = 5 × (50 + 50 − 5)A = 5 × 95.0A = 475.0 mm²

Weight follows from the area with no further geometry: m = A × 10⁻⁶ × ρ, where A is in mm², ρ in kg/m³ and m in kg/m. At 2,680 kg/m³ that is 1.2730 kg/m for the reference size above.

Area is a property of the geometry alone, so this table is the same for every material. It is what you enter into a stress calculation; the mass table is what you enter into an order.
Each row is one nominal size. Because the area is computed from your dimensions rather than read from a mill table, a non-standard size is just as accurate — put it into the calculator above rather than interpolating between rows.
The same angle (l section) in every material
Geometry is fixed and only density changes, so this table is the whole material-selection question in one view. Aluminum 5052-H32 is highlighted. The percentage column is against carbon steel, which is the figure most quotations are built on.

Same geometry throughout, so the only variable is density. Carbon steel is highlighted as the baseline.
A note on using this table for costing: mass is not price. Aluminium is roughly a third of steel's mass here, but per kilogram it costs several times more, so a straight swap rarely saves money — what it buys is reduced load on a structure or a vehicle.
About aluminum 5052-h32
The highest-strength common non-heat-treatable alloy and the best of the sheet alloys for marine service, with roughly twice the corrosion resistance of 6061 in salt water. Its 2,680 kg/m³ is marginally below 6061 — a 0.7 % difference, invisible on a take-off but real. It work-hardens rather than age-hardens, so it cannot be strengthened after forming and is normally supplied in H32. Preferred for fuel tanks, hull plate and formed panels that will see chloride.

About angle (l section)
The angle formula quietly removes a double-counted corner: A = t(a + b − t) is t times each leg, less one t² for the square where the legs overlap. Skipping that correction overstates the area of a 50 × 50 × 5 angle by 10 %. Angles also bend about neither leg — the governing axis passes through the centroid, which sits off both legs, and it is why an equal angle is normally used back-to-back with a twin where bending matters. This table holds legs equal; put unequal legs into the calculator when the drawing specifies them.
Specified as leg a × leg b × thickness. Say whether the toe is square or radiused, and whether it is equal-leg.

Frequently asked questions
How much does aluminum 5052-h32 angle (l section) weigh?
At the reference dimensions (a = 50 mm, b = 50 mm, t = 5 mm) a aluminum 5052-h32 angle (l section) of this size weighs 1.273 kg/m, or 0.855 lb/ft. The table above lists the figure for every standard size so you can read your size directly instead of scaling.
How is the weight of angle (l section) calculated?
Weight is cross-sectional area × length × density. For this shape the area is A = t · (a + b − t). At the reference dimensions that gives 475.0 mm², and multiplying by aluminum 5052-h32's density of 2,680 kg/m³ gives 1.273 kg/m. Nothing is looked up in a table — which is why a non-standard size is calculated just as accurately as a standard one.
Why does aluminum 5052-h32 weigh more or less than steel?
It is lighter than carbon steel for the same section — about 66 % lighter at 2,680 kg/m³. Density is the only variable: the cross-sectional area depends purely on geometry, so a angle (l section) of the same dimensions has the same area in every material and the mass simply scales with density. In this case the ratio is 0.3414× carbon steel.
What is the cross-sectional area of a angle (l section)?
The area depends only on the dimensions, not on the material, so it is identical whichever material you select: at the reference dimensions it is 475.0 mm² (0.7363 in²). That is the number you would enter into a stress or deflection calculation, and it is why changing material on this page never changes the area column.
Does a al 5052 angle (l section) weigh the same as a al 5052 part of a different shape?
No, and the difference is larger than most people expect. At equal nominal size, a square bar is 27.3 % heavier than a round bar, and a hollow section is typically 60–80 % lighter than the solid bar it replaces. Weight follows area, and area changes faster than dimensions do — which is exactly why this needs calculating rather than estimating.
Should I use AL 5052 weight or carbon steel weight for costing?
Use the material you are actually buying. At 2,680 kg/m³ against carbon steel's 7,850 kg/m³, the same angle (l section) differs by 65.9 % in mass. On a per-metre quote that is invisible; on a fabricated tonnage it is the difference between a margin and a loss. This page computes the steel figure as 3.729 kg/m for comparison.
