Aluminum 6061 T4 Sheet is solution heat treated and naturally aged giving it slightly lower tolerance accuracy than Aluminum 6061 T6, which undergoes artificial aging. T4 is also slightly less expensive than T6 and has a slightly lower ultimate tensile strength and yield strength, with a higher elongation percentage, which increases the formability of the T4 temper. Aluminum sheet 6061 T4 is also cost friendlier and has improved formability over T6. Aluminum T4 is solution heat treated, and naturally aged to a substantially stable condition.
Due to its physical properties aluminum sheet & plate is valued and sought after choice metal for many different industrial applications, some of which include: Roofing Gutters Wall panels Aerospace Transportation Construction
“the composition of 1100 or 1060 aluminum plates pure aluminum Aluminum content greater than 99% is called pure aluminum, 1100 aluminum sheet content is 99%, and 1060 aluminum content is 99.6%. Other ingredients are iron and silicon.”
