Abstract (en)
[origin: WO2015147648A1] Method for the manufacturing of products with anodized high gloss surfaces from extruded profiles of Ai-Mg-Si or AS-Mg-Si-Cu, where the alloys initially are cast to extrusion billet(s), containing in wt.% Si: 0,25-1,00 Mg: 0,25-1,00 Fe: 0,00-0,15 Cu: 0,00-0,30 Mn: 0,00 -- 0,20 Cr: 0,00-0,10 Zr: 0,00 -0,10 Sc: 0.00 -0,10 Zn: 0,00-0,10 Ti: 0,00-0,05., and Including incidental impurities and balance A.L a) where the billet is homogenised at a holding temperature between 480°C and 620°C and soaked at this temperature for 0-12 hours, where after the billet is subjected to cooling from the homogenisation temperature at. a rate of 150°C/h or faster, b) the billet is preheated to a temperature between 400 and 540°C and extruded preferably to a solid shape profile and cooled rapidly down to room temperature, c) optionally artificially ageing the profile, d) deforming the profile more than 10% by a cold roiling operation, whereafter e) the profile is flash annealed with a heating time of maximum two minutes to a temperature of between 450 ~ 530 °C for not more than 5 minutes and subsequently quenched, and f) optionally the profile after flash annealing is further subjected to a cold deforming operation to remove residua! stresses from cooling and adjusting dimensional tolerances, and g) the profile is finally aged.
