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 4.180 kg/m (2.809 lb/ft). Against carbon steel's 7,850 kg/m³ that is +12.1 % — 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 8,800 kg/m³ that is 4.1800 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.

How to read this table

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. Bronze C93200 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 bronze c93200

Tin-lead bearing bronze, the standard material for plain bushes and wear plates because its microstructure carries a soft lead phase that acts as a built-in lubricant. At 8,800 kg/m³ it sits between copper and brass, and being a cast alloy its density genuinely varies more than the wrought metals — 8,700 to 9,000 kg/m³ is normal across bronze chemistries, so a take-off on a large cast bush should come from the caster’s certificate, not from a table.

Density
8,800 kg/m³ = 0.3179 lb/in³ · 1.1210× carbon steel · typical spread ±3 %
Specification
ASTM B505 (UNS C93200, bearing bronze)
Equivalents
SAE 660 · EN CW458K · GB ZQSn6-6-3
Typical uses
Plain bearings and bushes · Worm gears · Pump and valve components · Wear plates
Weight-relevant caution

Cast alloys carry higher density uncertainty than wrought. Typical spread 8,700–9,000 kg/m³.

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.

When ordering

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 bronze c93200 angle (l section) weigh?

At the reference dimensions (a = 50 mm, b = 50 mm, t = 5 mm) a bronze c93200 angle (l section) of this size weighs 4.180 kg/m, or 2.809 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 bronze c93200's density of 8,800 kg/m³ gives 4.180 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 bronze c93200 weigh more or less than steel?

It is heavier than carbon steel for the same section — about 12 % heavier at 8,800 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 1.1210× 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 bronze angle (l section) weigh the same as a bronze 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 Bronze weight or carbon steel weight for costing?

Use the material you are actually buying. At 8,800 kg/m³ against carbon steel's 7,850 kg/m³, the same angle (l section) differs by 12.1 % 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.

Other materials, same angle (l section)

The same geometry in every material, so the only variable is density.
