Aluminum PipeThis is a 6061 T6 Aluminum schedule 80, 1 1 2" X 20' plain end pipe. T6 temper 6061 has been treated to provide the maximum precipitation hardening (and therefore maximum yield strength) for a 6061 aluminum alloy. It has an ultimate tensile strength of at least 290 MPa (42 ksi) and yield strength of at least 240 MPa (35 ksi). Excellent joining characteristics, good acceptance of applied coatings. Combines relatively high strength, good workability,
