What is Aluminum 6061 T4?

2019-02-18

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.

6063 is widely used as 6063 aluminum sheet plate and 6063 aluminum profiles, so 6063 is applied in building profiles, irrigation pipes, vehicles, gantry, furniture, lifts, fences, etc. 6061 aluminum alloy is widely used as 6061 aluminum sheet plate and 6061 aluminum coil, there are generally T6, T4 and T651, 6061 aluminum plate has hardness of more than 95, so it is widely used in the machining industry. 6061 aluminum alloy can be applied in the place which requires a variety of industrial structures with high strength, weldability, and corrosion resistance, such as pipes, rods, and shaped timber for trucks, tower buildings, ships, trams, furniture, mechanical parts, precision machining, etc. During the applications, 6061 aluminum plate is used more wide than 6063 aluminum because it has higher strength.

6061 aluminum sheet and 6063 aluminum sheet are both belong to the 6000 series aluminum alloy, they are similar but still have difference. The main alloying elements of 6061 and 6063 aluminum alloy are magnesium and silicon. 6061 aluminum has more alloy elements content than 6063 aluminum. With excellent processing performance, excellent weldability, extrusion and electroplating, good corrosion resistance, toughness. Easy to polish, coated, and anodized, is a typical extruded alloy.
