Titanium Grade 2 Angle (L Section) Weight
Mass per metre and per foot for titanium grade 2 angle (l section) at 4,510 kg/m³ (ASTM B265 / B348 (UNS R50400)). Every figure is for the section as drawn. A 6 m length of this size weighs 12.9 kg (28.8 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 2.142 kg/m (1.440 lb/ft). Against carbon steel's 7,850 kg/m³ that is -42.5 % — 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 4,510 kg/m³ that is 2.1423 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. Titanium Grade 2 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 titanium grade 2
Commercially pure titanium, the workhorse corrosion grade rather than the aerospace high-strength one. Density 4,510 kg/m³ gives it 57 % of steel’s mass with a comparable tensile strength, which is the headline — but titanium’s real advantage in chemical plant is a passive oxide film that survives chlorides, wet chlorine and oxidising acids that destroy stainless. It is expensive enough that the mass change is a secondary concern to the corrosion allowance it lets you remove.

Poor machinability — low thermal conductivity causes heat to concentrate at the cutting edge. Titanium is also combustible as fine swarf.
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 titanium grade 2 angle (l section) weigh?
At the reference dimensions (a = 50 mm, b = 50 mm, t = 5 mm) a titanium grade 2 angle (l section) of this size weighs 2.142 kg/m, or 1.440 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 titanium grade 2's density of 4,510 kg/m³ gives 2.142 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 titanium grade 2 weigh more or less than steel?
It is lighter than carbon steel for the same section — about 43 % lighter at 4,510 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 0.5745× 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 ti gr 2 angle (l section) weigh the same as a ti gr 2 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 Ti Gr 2 weight or carbon steel weight for costing?
Use the material you are actually buying. At 4,510 kg/m³ against carbon steel's 7,850 kg/m³, the same angle (l section) differs by 42.5 % 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.
