6061-T6 Aluminum Technical Data
T6 temper 6061 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 45,000 psi (310 MPa) ultimate tensile strength and 40,000 psi (275 MPa) yield strength.
In thicknesses of 0.250 inch (6.35 mm) or less, 6061-T6 has an elongation of 8% or more. In thicker sections, elongation is approximately 10%.
T651 temper has similar mechanical properties.
The typical thermal conductivity value for 6061-T6 at 80°C is approximately 152 W/m K.
A material data sheet defines the fatigue limit under cyclic loading as 14,000 psi (100 MPa) for 500,000,000 completely reversed cycles using a standard R.R. Moore test machine and specimen.
Long Radius Elbow Design
The long-radius configuration provides a gradual 90-degree change in direction in a piping run. Compared with a tighter-radius elbow, the longer bend radius creates a smoother transition through the fitting.
This configuration is suited for compatible aluminum piping layouts where a welded directional change is required.
Product Features
Seamless Construction
These elbows are supplied in seamless Schedule 40 and Schedule 80 configurations for integration into compatible welded aluminum piping systems.
6061-T6 Material
6061-T6 aluminum combines useful mechanical strength with the lightweight and corrosion-resistant characteristics associated with aluminum piping components.
Schedule 40 & Schedule 80
Schedule 40
Schedule 40 elbows are intended to match compatible Schedule 40 aluminum pipe dimensions and wall thicknesses.
Schedule 80
Schedule 80 elbows are intended to match compatible Schedule 80 aluminum pipe dimensions and wall thicknesses.

Fatigue Performance Considerations
The referenced fatigue value is based on a standard R.R. Moore test machine and specimen under completely reversed cyclic loading.
Because aluminum does not exhibit a clearly defined fatigue-limit “knee” on its S-N curve, fatigue performance should not be interpreted as a fixed infinite-life value. Actual service performance can vary substantially based on application-specific factors.

Frequently Asked Questions
What material are these elbows made from?
These elbows are manufactured from 6061-T6 aluminum.
What schedules are available?
These aluminum weld elbows are available in Schedule 40 and Schedule 80.
Are these fittings seamless?
Yes. The original product specification identifies them as seamless fittings.
What is the minimum tensile strength of 6061-T6?
The original technical information lists 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 minimum yield strength of 6061-T6?
The original technical information lists a minimum yield strength of 35,000 psi (241 MPa), with a more typical value of approximately 40,000 psi (275 MPa).
What elongation is listed for 6061-T6?
For sections 0.250" (6.35 mm) thick or less, elongation is listed as 8% or more. In thicker sections, elongation is listed at approximately 10%.
What thermal conductivity is listed for 6061-T6?
The original technical information lists a typical thermal conductivity of approximately 152 W/m K at 80°C.
What fatigue limit is referenced?
The original technical information references a fatigue limit of 14,000 psi (100 MPa) for 500,000,000 completely reversed cycles using a standard R.R. Moore test machine and specimen.
Does aluminum have a defined infinite-life fatigue limit?
The original technical information notes that aluminum does not exhibit a clearly defined “knee” on its S-N graph, so the number of cycles considered equivalent to infinite life is subject to interpretation.
What factors can affect the actual fatigue limit?
The original description notes that loading, stress gradient, and surface finish can dramatically affect fatigue performance in actual applications.
Are these elbows made in the USA?
Yes. The product is identified as domestic and made in the USA with precision craftsmanship.
