What Is Aluminum Alloy 5052?
Aluminum 5052 is a non-heat-treatable aluminum-magnesium alloy containing approximately 2.2–2.8% magnesiumand 0.15–0.35% chromium.
It is widely used where a combination of formability, weldability, fatigue resistance and corrosion resistance is required.
The main characteristics of 5052 aluminum include:
- Good forming and bending performance
- Good weldability
- Moderate mechanical strength
- Good fatigue resistance
- Good resistance to marine atmospheres
- Low material density
- Good thermal conductivity
5052 cannot be strengthened by conventional solution heat treatment and artificial aging. Its strength is increased mainly through cold working.
Mechanical properties depend on the temper, product form, thickness and fabrication process. Properties listed for sheet or plate should not automatically be applied to formed or welded pipe fittings.
5052 Aluminum Elbows
90° Long-Radius Elbow
A 5052 aluminum 90-degree long-radius elbow changes the direction of a piping system by 90 degrees.
The standard long-radius centerline is generally 1.5 times the nominal pipe diameter. LR elbows provide a smoother flow transition and are commonly selected where pressure loss and turbulence need to be reduced.
90° Short-Radius Elbow
A short-radius elbow normally has a centerline radius equal to approximately one nominal pipe diameter.
SR elbows are suitable for compact piping layouts where installation space is limited.
Custom-Angle Elbows
In addition to 45°, 90° and 180° fittings, we can manufacture custom angles such as:
- 22.5°
- 30°
- 60°
- Drawing-specific angles
Nonstandard angles and radii are manufactured according to approved customer drawings.
5052 Aluminum Tees
We supply both equal tees and reducing tees.
An equal tee has the same run and branch size, while a reducing tee has a smaller branch connection.
Available constructions include:
- Seamless formed tee
- Pressed tee
- Fabricated welded tee
- Custom branch fitting
For fabricated tees, the inquiry should identify the required welding procedure, NDT method and acceptance criteria.
5052 Aluminum Reducers
Available reducer types include:
- Concentric reducer
- Eccentric reducer
- Seamless formed reducer
- Fabricated welded reducer
- Custom transition fitting
For eccentric reducers, the required orientation should be clearly stated as:
- Flat on top
- Flat on bottom
- Drawing-defined orientation
The inquiry should include both end diameters, wall thicknesses, overall length and minimum finished wall thickness.
5052 Aluminum Caps and Stub Ends
Aluminum Caps
5052 aluminum caps are used to close pipe ends, nozzles and equipment connections.
They may be formed or fabricated according to ASME dimensional patterns or customer drawings.
Aluminum Stub Ends
5052 stub ends are used with compatible loose backing flanges in lap-joint connections.
Available designs include:
- Short-pattern stub ends
- Long-pattern stub ends
- Custom collar pieces
- Drawing-specific lap-joint ends
The face diameter, lap thickness, corner radius and overall length should be stated in the inquiry.
For compatible flange products, refer to our 5052 Aluminum Flanges
ASTM B241, ASTM B361 and ASME B16.9
These standards serve different purposes.
| Standard | Main Function |
|---|---|
| ASTM B241 / ASME SB-241 | Seamless aluminum pipe and seamless extruded tube |
| ASTM B361 / ASME SB-361 | Factory-made wrought aluminum welding fittings |
| ASME B16.9 | Butt-weld fitting dimensions, tolerances and marking |
| ASME B16.25 | Butt-welding-end preparation |
| Approved drawing | Nonstandard sizes, angles and fabricated fittings |
ASTM B241 may specify the seamless 5052 pipe used as the starting material for a formed elbow.
ASTM B361 is the finished aluminum welding-fitting specification. Compliance should be confirmed against the alloy, temper and product type listed in the ordered edition.
ASME B16.9 provides the dimensional framework but does not independently establish the aluminum material grade.
A complete product description can be written as:
Aluminum Alloy 5052-O, 90° Long-Radius Butt-Weld Elbow, manufactured from ASTM B241 seamless pipe, dimensions to ASME B16.9, with minimum finished wall thickness as specified.
Applications
5052 aluminum elbows and pipe fittings may be used in:
- Marine auxiliary equipment
- Shipbuilding components
- Heat exchangers
- Storage tanks
- Lightweight industrial piping
- Food-processing equipment
- Chemical equipment
- Hydraulic systems
- Custom machinery
- Prefabricated aluminum pipe spools
Final suitability depends on the actual fluid, design pressure, temperature, welding condition, fatigue loading and galvanic-corrosion risk.
For more demanding marine piping systems, compare 5052 with our 5083 Aluminum Pipe Fittings and 90 Degree 5083 Aluminum Elbows.
5052 vs 5083 Aluminum Pipe Fittings
| Comparison | 5052 Aluminum | 5083 Aluminum |
|---|---|---|
| Main alloying element | Magnesium | Higher magnesium content |
| Relative strength | Moderate | Generally higher |
| Formability | Very good | Good, especially in annealed temper |
| Weldability | Good | Very good |
| Marine applications | Suitable for many components | More common in demanding welded marine structures |
| Typical products | Light-duty fittings, tanks and fabricated parts | Marine elbows, piping and structural components |
5052 is often selected where forming capability and moderate strength are important. 5083 is generally preferred where higher strength and more demanding marine-service performance are required.

Frequently Asked Questions
What is a 5052 aluminum elbow?
A 5052 aluminum elbow is a formed or fabricated pipe fitting made from Aluminum Alloy 5052 and used to change the direction of an aluminum piping system
Is ASTM B241 a finished fitting standard?
No. ASTM B241 covers seamless aluminum pipe and seamless extruded tube. The pipe may be used as the starting material for a formed elbow.
Can 5052 pipe fittings comply with ASTM B361?
Compliance may be possible when the alloy, temper, construction and fitting type are included in the ordered ASTM B361 or ASME SB-361 edition.
Can 5052 fittings use ASME B16.9 dimensions?
Yes. Elbows, tees and reducers can be manufactured to ASME B16.9 dimensional patterns where technically applicable.
Is 5052 suitable for marine piping?
5052 offers good resistance to marine atmospheres and wet environments. Final suitability depends on fluid chemistry, temperature, welding condition and galvanic contact.
What is the difference between LR and SR elbows?
A long-radius elbow normally has a centerline radius of 1.5D, while a short-radius elbow normally has a radius of 1D.
