6061 and 6082 aluminum alloy are the alloy in the aluminum-magnesium-silicon family (6xxx series). The main difference is that the composition ratios of silicon and magnesium in 6082 and 6061 are different. But no matter chemical composition or performance, alloy 6061 and 6082 are very similar, and we think they are instead able. Alloy 6061 is very commonly used in North America, while 6082 is commonly used in Europe. Since 6061 is our regular stock material, it can be considered to use 6061 instead of 6082 in production.
