6065F

6065F is a designation found in some aluminum alloy catalogs to denote a variant of the 6065 aluminum alloy in the F (as-fabricated) temper. The 6065 family is a magnesium–silicon alloy in the 6xxx series, offering a balance of strength, formability, and corrosion resistance, and it is commonly used for extruded profiles and structural components.

As the F temper, 6065F is delivered in an as-fabricated condition, without artificial aging or significant heat treatment. This means the material generally has lower strength and hardness than its heat-treated counterparts (such as T6 or T5 tempers) but retains good ductility and weldability. The exact mechanical properties can vary by supplier and production route.

The composition of 6065 alloys centers on magnesium and silicon as the primary alloying elements, with other elements present within standard allowable ranges. Because 6065F is a designation used by specific producers, exact chemical limits and properties can differ between sources. Typical applications for 6065-type alloys include extruded architectural and structural components, automotive parts, and other fabrications where moderate strength, good corrosion resistance, and workable form are desirable.

Availability and standards concerning 6065F can vary by region and manufacturer. Users should consult the supplier’s data sheet and material certification to confirm chemical composition, mechanical properties, and temper designation for a given lot, and to ensure compatibility with design requirements and processing methods.
