Anodizing process oriented to castings and die-castings,
characterized by a high silicon content. In addition to a good aesthetic
appearance, it stands out for its very high resistance to corrosion.
The aluminum treated with the Zancofuso® process satisfactorily withstands
atmospheric agents and chemical solutions with a pH varying from 4 to 9.
Its duration to corrosion, in addition to depend on the percentage of
silicon of the base material present in the fusion or die-casting, it
also depends on the thickness of the coating itself.
Thicknesses are determined according to the final purpose. For parts used in closed environments, a layer of 5-10 microns is sufficient. For weathered parts a layer of 10 to 20 microns is recommended.
Zancofuso® was developed to solve problems on die-cast
alloys with a percentage of silicon higher than 10%. It’s important having as
base material a surface as much homogeneous as possible.
