Rolling ingots are used for the production of G.AL® C250 ELOX PLUS 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, we produce aluminum plates which have excellent characteristics for anodizing and hard anodizing and thus the fulfil 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.

Printing industry

Hard, uniform and smooth, functional surfaces are in demand for printing plates, for example, which also have to satisfy optical demands. G.AL® C250 ELOX PLUS exceeds these requirements.

If anodized components must be aesthetically appealing or reproducible, G.AL® C250 ELOX PLUS is the right choice. Please note our anodizing specifications.
