Aluminum 6082 has a higher yield strength than 6063 and is better for projects where the component will be exposed to significant load and force. It will maintain its shape better over time and provide greater resistance to fatigue.
6063 aluminum has lower yield strength but is more corrosion resistant and often used in applications such as window frames, door frames, roofs, and sign frames.
Elongation
Elongation is the measure of how much a material can stretch before it breaks, so when deciding what alloy to use, it's important to look at how much strain it can handle. An idiom that may come in handy is 'bend but don't break'.
When considering aluminum alloys 6082 and 6063 for your project, you'll want to understand their respective elongation properties. Aluminum alloy 6082 is known for its high yield strength as well as its excellent elongation capabilities—up to 14% in some cases. In comparison, aluminum alloy 6063 has an even higher yield strength than 6082 but a lower elongation capability of around 8%.
This means that 6082 will be able to handle more strain before breaking than 6063 will. Ultimately, the choice between these two alloys depends on the specific needs of your project and which one can provide the most consistent results while meeting those requirements.
