What is the difference between aluminum alloy 6063 and 6061?
2022-11-08
There are many specifications of aluminum, 6061 and 6063 are two of them. There are also some differences between the two. The difference between the two mainly includes three aspects, composition, use and production process. The composition of 6061 aluminum is more than that of 6063, and its hardness is stronger; 6063 is mostly used for architectural aluminum doors and windows, curtain wall frames, etc., while 6061 is mostly used for welding, processing, etc.; at the same time, the production process of 6061 is more complicated than 6063. 1. The composition is different The composition of 6063 aluminum alloy contains 0.4% Si and 0.7% Mg, the strength of hard material is 295Mpa, and the strength of soft material is 111Mpa. It is used in tubular railings, furniture, frames, and extruded profiles for construction. The composition of 6061 aluminum alloy contains 0.6%Mg, 0.25%Cu, 1.0%Mg, 0.09%Cr, the hard strength is 316Mpa, and the soft strength is 127Mpa. It is used in corrosion-resistant structures, trucks, ships, vehicles, furniture, etc.
2. Different uses 6063 aluminum alloy is widely used in the frame of aluminum doors, windows and curtain walls in buildings. In order to ensure that doors, windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decorative performance, the requirements for the comprehensive performance of aluminum alloy profiles are much higher than those of industrial Profile standard. 6061 aluminum alloy is a high-quality aluminum alloy product produced by heat treatment and pre-stretching process. It has many characteristics of magnesium and silicon alloys, excellent processing performance, excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness and processing It has excellent characteristics such as no deformation, compact and defect-free material, easy polishing, easy coloring film, and excellent oxidation effect. 3. The production process is different The T6 process of 6061 is: the solution treatment temperature is 530 degrees, the T6 state of artificial aging is 160 degrees for plates, and 175 degrees for bars and plates with a thickness of more than 80 degrees. The T5 state of 6063 is air-cooled and artificially aged. The deformation coefficient is small, easy to control, and the hardness is average. The T6 state is water-cooled, the deformation coefficient is large, it is not easy to control, and the hardness is high.
