Aluminum alloys are divided into deformed aluminum alloys and cast aluminum alloys according to their uses. Deformed aluminum alloys include daily-used aluminum alloy doors and windows, and space shuttle structural materials. They can be heat treated or not heat treated according to different use requirements; the other type is cast aluminum alloys, which mainly include aluminum-silicon alloys, aluminum-copper alloys, and aluminum-magnesium alloys. , aluminum-zinc alloy and aluminum rare earth alloy, etc.
In the actual production process, cast aluminum alloys are classified according to the content of various chemical elements. The smelting process needs to add or reduce the amount of raw materials according to the actual chemical composition. The finished aluminum ingots supplied by some manufacturers already contain various alloying elements required for the product.
There is basically no need to add other additional chemical elements during the smelting process, and there is no need to proportion directly. When melted into liquid aluminum, there is no problem with the order of addition. This type of aluminum alloy is suitable for products with a single structure.
