The 8″ Aluminum Structural Beam is an extruded raw aluminum I-beam. Made from marine-grade 6061-T6 US aluminum. 8 in. web x 5 in. flange measurements. The beam weighs 7.023 lbs. per linear foot. Drilling into the beam compromises the beam’s integrity. The 12 ft. 6 in. beam can be shipped, freight loose beam. The 25 ft. beam is local pickup only. Sold by BH-USA.
6061-T6 Marine-Grade US Aluminum
6061-T6 is an all-around popular grade of aluminum. Commonly used in marine applications. Very good corrosion resistance and is precipitation hardened. These grades, for the most part, have additional chromium and manganese to help protect them from corrosive marine conditions. The aluminum structural beam falls into this category.
T6 temper 6061 US Aluminum
T6 temper 6061 has an ultimate tensile strength of at least 290 MPa (42,000 psi) and yield strength of at least 240 MPa (35,000 psi). More typical values are 310 MPa (45 ksi) and 270 MPa (39 ksi), respectively. In thicknesses of 6.35 mm (0.250 in) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%. T651 temper has similar mechanical properties. The typical value for thermal conductivity for 6061-T6 at 25 °C (77 °F) is around 152 W/m K. A material data sheet defines the fatigue limit under cyclic load as 97 MPa (14,000 psi) for 500,000,000 completely reversed cycles using a standard RR Moore test machine and specimen.
