Description

Rolling ingots are used for the production of G.AL® C250 ELOXPLUS plates. The chemical composition of these ingots is considerably limited in accordance with the GLEICH factory standard and extensive cleaning of the melt and specific casting parameters are required. Together with the specially-developed parameters of the subsequent heat treatment, Gleich produces aluminum plates which have excellent characteristics for anodizing and hard anodizing and thus the fulfill the highest technical and optical applications. As with G.AL® C250, G.AL® C250 ELOX PLUS is a precision cast plate, precision machined on both sides with protective foil.
