6061 aluminum sheet is a popular material due to its strength, low weight, formability and resistance to moisture, heat and corrosion. 6061 aluminum sheet has an ultimate tensile strength of at least 42,000 psi and yield strength of at least 35,000 psi making it ideal for a wide range of applications. 6061 aluminum is the most widely used aluminum grade.
6063 is widely used as 6063 aluminum sheet sheet and 6063 aluminum profiles, so 6063 is applied in building profiles, irrigation tubes, vehicles, gantry, furniture, lifts, fences, etc. 6061 aluminum alloy is widely used as 6061 aluminum sheet sheet and 6061 aluminum coil, there are generally T6, T4 and T651, 6061 aluminum sheet 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 tubes, rodss, and shaped timber for trucks, tower buildings, ships, trams, furniture, mechanical parts, precision machining, etc. During the applications, 6061 aluminum sheet 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.
