For those of us in the industry, we know for sure that 4 x 8 aluminum sheet won't rust, but for those users, they just want you to answer one of these questions in time so that they can feel at ease in future use, and that's it. So when someone asks you these questions, don't ignore him, we should tell them that aluminum will not rust and can be used with confidence.

Why doesn't aluminum rust on it? Let's take a look.
In fact, in the process of aluminum processing, we can add some other metal elements to the anti-corrosion of aluminum, so that the effect of anti-rust can be achieved. The aluminum ring sold on the market is equivalent to the 3000 series aluminum plate. Manganese alloy. If we add it to the aluminum-magnesium alloy, the density of aluminum will be relatively low, and the strength will increase, so it becomes an aluminum-magnesium alloy.
