The 6082 doesn't mean anything without it's temper #... like the 6061T6 gives you. T6 is pretty damn hard stuff as aluminum goes (T0 is untempered) and 6061T6 is commonly used in heavier duty aircraft structure. Generally if 6061T6 isn't strong enough, the next step slightly up is 7075T6, if it has to be stronger than that, it'll be steel or titanium. I'm not exactly sure of the properties of 6082, but you could look it up on the net. The different numbers stand for what other materials are alloyed with aluminum to make it stronger. Probably something that makes it easier to polish up nice, as 6061 is not one of the more lusterous alloys.
