Description
Aluminum Short Radius Weld 90° Elbow
Aluminum Short Radius Weld 90° Elbows are designed for welded aluminum piping systems requiring a compact 90-degree change in direction. Manufactured from 6061-T6 aluminum, these seamless elbows are available in Schedule 40 and Schedule 80 configurations.
The short-radius configuration provides a tighter directional change than a long-radius elbow, making it useful where installation space is limited. These fittings are domestically manufactured in the USA.

Short Radius Design
The short-radius configuration provides a compact 90-degree change in direction for welded aluminum piping. Compared with a long-radius elbow, the tighter turn requires less installation space and can be useful in piping layouts where clearance is limited.
Confirm the required elbow radius, nominal pipe size, and schedule for the piping system before ordering.
6061-T6 Aluminum Technical Properties
T6 temper 6061 aluminum has an ultimate tensile strength of at least 42,000 PSI (300 MPa) and a yield strength of at least 35,000 PSI (241 MPa). More typical values are approximately 45,000 PSI (310 MPa) ultimate tensile strength and 40,000 PSI (275 MPa) yield strength.
In thicknesses of 0.250" (6.35 mm) or less, 6061-T6 has elongation of 8% or more. In thicker sections, elongation is approximately 10%.
T651 temper has similar mechanical properties to T6 temper.
Thermal Conductivity
The typical thermal conductivity value for 6061-T6 aluminum at 80°C is approximately 152 W/m K.
Fatigue Performance
A published material data sheet defines the fatigue limit under cyclic loading as approximately 14,000 PSI (100 MPa) for 500,000,000 completely reversed cycles using a standard RR Moore test machine and specimen.
Aluminum does not exhibit a sharply defined “knee” on its S-N fatigue graph. Because of this, there can be debate over how many cycles should be considered equivalent to “infinite life.”
The actual fatigue limit for a specific application can be substantially affected by conventional de-rating factors, including loading conditions, stress gradient, and surface finish.

Frequently Asked Questions
What material are these elbows made from?
These short-radius 90° weld elbows are manufactured from 6061-T6 aluminum.
What schedules are available?
The elbows are available in Schedule 40 and Schedule 80 configurations.
Are these elbows seamless?
Yes. These aluminum weld elbows are identified as seamless.
What is a short-radius 90° elbow?
A short-radius elbow provides a tighter 90-degree directional change than a long-radius elbow, allowing it to fit into more compact piping layouts.
What is the tensile strength of 6061-T6 aluminum?
The supplied technical information states a minimum ultimate tensile strength of 42,000 PSI (300 MPa), with a more typical value of approximately 45,000 PSI (310 MPa).
What is the yield strength of 6061-T6 aluminum?
The supplied technical information states a minimum yield strength of 35,000 PSI (241 MPa), with a more typical value of approximately 40,000 PSI (275 MPa).
What elongation does 6061-T6 aluminum provide?
For thicknesses of 0.250" (6.35 mm) or less, elongation is 8% or more. In thicker sections, elongation is approximately 10%.
What is the thermal conductivity of 6061-T6 aluminum?
The typical thermal conductivity at 80°C is approximately 152 W/m K.
What is the published fatigue limit?
The supplied material information identifies a fatigue limit of approximately 14,000 PSI (100 MPa) at 500,000,000 completely reversed cycles using a standard RR Moore test machine and specimen.
Does aluminum have a defined infinite fatigue life?
Aluminum does not exhibit a sharply defined knee on its S-N fatigue graph, so the number of cycles considered equivalent to infinite life can vary. Actual fatigue performance can also be significantly affected by loading, stress gradient, and surface finish.
Are these elbows designed to be welded?
Yes. They are designed for incorporation into compatible welded aluminum piping systems.
Are these aluminum elbows made in the USA?
Yes. These elbows are identified as domestic products made in the USA.
How do I determine the correct schedule?
Select the elbow schedule to match the pipe and requirements of the piping system. The pipe chart in the Product Documentation section provides common diameter and wall-thickness information.
