What is the density of 6061?

2700 kg/m³ — the figure the weight calculators on this site use for 6061. The value is Hydro / Aluminium Association style alloy data’s.

What is the chemical composition of 6061?

Si 0.4–0.8, Mn ≤ 0.15, Cr 0.04–0.35, Cu 0.15–0.4, in mass %, to AA/ASTM chemistry reference. An element the standard sets no requirement for is left blank here rather than written as zero.

What are the mechanical properties of 6061?

Tensile ≥ 290 MPa, Yield ≥ 240 MPa, Elongation min ≥ 10 % — ASTM B209, Sheet/Plate, T6. Those are the standard’s requirements; the mill test certificate governs the metal delivered.

What is 6061 equivalent to?

6082. Equivalents are approximate, never identical — compare the certificate against your specification before substituting.
