Abstract (en)
[origin: WO2021254852A1] The present invention relates to a reliable high extrusion rate production method for recycle friendly aluminum soft alloy of the type 6060X, which besides Al,Mg and Si contains important amounts of Cu, Zn, Fe and Mn as alloying elements, followed by an pretreatment with an alkaline or acid etching of at least 1,0 prefarably 2 gram/m2 yielding to powdercoated aluminum profiles with a very high corrosion resistance after powder coating for the most common conversion ( Ti, Zr,Ti/Zr, preanodisation, etc ) – powdercoating systems available in the market.
