"Raw aluminum" is the "cast aluminum alloy" in the aluminum industry, which is mainly based on aluminum-silicon, or some alloying elements are added to the casting molding, that is, the product is a casting. Aluminum products with rough surfaces are mostly raw aluminum. Pig aluminium is impure aluminum, and like pig iron, it shatters when struck hard.
"Wrought aluminum" is "deformed aluminum alloy", which is divided into seven alloy series in the world, namely: 1 series - pure aluminum, 2 series - aluminum copper, 3 series - aluminum-manganese, 4 series - aluminum-silicon, 5 series - aluminum-magnesium, 6-aluminum-magnesium-silicon, 7 series - aluminum-zinc-magnesium, aluminum pipes, aluminum bars, aluminum profiles, aluminum wires, aluminum plates, aluminum foils, etc. are all deformed aluminum alloys, which are processed and deformed, and they include pure aluminum and aluminum alloys; "Alloy" is not a category, aluminum products include pure aluminum and aluminum alloy products. "Raw aluminum" and "wrought aluminum" are now called "cast aluminum" and "deformed aluminum". The so-called "scrap aluminum" refers to a variety of aluminum materials that are discarded into the market after use, and the aluminum scrap on the market can be divided into "raw aluminum" (that is, high silicon content) and "cooked aluminum", pay attention to the use of alloy composition in strict accordance with the classification.
