Many domestic aluminum roll manufacturers, due to different conditions, the quality of the aluminum plates produced is uneven, so the prices of aluminum plates are also very different. But the price of domestic aluminum is basically flat. In the process of processing, since there is such a large price difference, the quality difference is very large.
The decisive factor affecting the quality of aluminum plates is 6063 alloys. It is a alloy prepared with aluminum, magnesium, and silicon as its main elements. Each element has a certain content, and the price of magnesium is very high. In order to reduce costs, some manufacturers reduce the content of magnesium to lower allowable content. Some even reduce the magnesium content below the allowable low content. Some factories add scrap iron and scrap aluminum pots in the alloy. Basically, it is not necessary to say that 6063 alloys are needed. In this way, the mechanical strength of aluminum profiles is very low. It is easy to bend with both hands. It is commonly known as "noodles".
When regular aluminum roll manufacturers have their own internal standards when preparing aluminum aluminum plate composition, that is, within the content range of various elements, each manufacturer has its own small range of changes. The proportion of aluminum, magnesium, and silicon is strict. Each factory has its own data and keeps confidential. Only qualified alloys can ensure quality, otherwise the processing method will not improve the quality in the future.
