Folk called "raw aluminum" is the aluminum industry on the "cast aluminum alloy" it is mainly aluminum - silicon, or add some alloy elements, for casting molding, that is, the product is casting. Rough surface of aluminum products, mostly raw aluminum. Raw aluminum is not pure aluminum, it and pig iron, hard to break.
"Wrought aluminum" is "deformed aluminum alloy", the world is divided into seven alloy series, namely: 1 series - pure aluminum, 2 series - aluminum copper, 3 series - aluminum manganese, 4 series - aluminum silicon, 5 series - aluminum magnesium, 6 series - aluminum magnesium silicon, 7 series - aluminum zinc magnesium, aluminum pipe, aluminum bar, aluminum profile, aluminum wire, aluminum plate, aluminum foil and other are deformed aluminum alloy category, after processing deformation forming, they include pure aluminum and aluminum alloy; "Alloy" is not a class, aluminum products include pure aluminum and aluminum alloy products. "Raw" and "wrought" aluminum are now called "cast" and "deformed aluminum." The so-called "waste aluminum" refers to all kinds of aluminum materials that enter the market after being used. In addition to "raw aluminum" (that is, high silicon content) and "wrought aluminum", the aluminum waste on the market can be classified strictly by alloy.
