"Cold-rolled aluminum" refers to the aluminum industry, "casting aluminum alloy", which is mainly aluminum - silicon, or add some alloying elements for casting molding, the products are castings. Surface roughness of aluminum products, mostly cold-rolled aluminum. Cold-rolled aluminum is not pure aluminum, it and pig iron, like a knock on the broken hard.(aluminium plate 20mm thick)
"Hot-rolled aluminum plate" is "deformed aluminum alloy", the international seven alloy series, namely: 1 series - pure aluminum, 2 series - aluminum copper, 3 series - Al-Mn, 4 series - Al-Si, 5 Series - Al Aluminum, aluminum, aluminum foil, etc. are deformed aluminum alloy category, the processing deformation of forming, which include pure aluminum and aluminum alloy, Aluminum alloy; "alloy" not a class, aluminum products include pure aluminum and aluminum alloy products. "Cold rolled aluminum" and "hot rolled (marine aluminium plate)aluminum" are now called "cast aluminum" and "deformed aluminum". The so-called "scrap aluminum" refers to the use of waste into the market after the various aluminum materials, aluminum scrap on the market in addition to the "cold rolled aluminum" (that is, high silicon) and "hot rolled aluminum" , Pay attention to strictly according to alloy composition class use. aluminium plate in coil
