The present invention provides a new aluminum alloy material which may be used for a core alloy of a corrosion-resistant brazing sheet. This core alloy displays with high strength, and good corrosion resistance for use in heat exchangers. This aluminum alloy material was made by direct chill (DC) casting. The present inventions also provides corrosion-resistant brazing sheet packages including the aluminum alloy material as a core and one or more cladding layers.

This application discloses a corrosion-resistant brazing sheet package for use in manufacturing tubing. The brazing sheet package includes a core layer of aluminum-containing alloy comprising from 0.1 wt % to 0.2 wt % of titanium. The core layer has a first side and a second side. The first side of the core layer is adjacent to a first cladding layer to form a first interface. The second side of the core layer is adjacent to a second cladding layer to form a second interface. The first cladding layer and the second cladding layer each include from 2.5 wt % to 4.0 wt % of zinc.

Provided herein is a hydrogen permeation barrier coating, a coated substrate, and methods of coating a substrate.

A method for decorating metallic or non-metallic surfaces treated with Physical Void Deposition, PVD, comprising: an electrochemical activation action of the decoration by means of an electrical circuit with electrodes in electrical contact and for at least one thereof with the mediation of an electrolytic solution towards a surface being treated; an electrically conductive surface facing one of said electrodes to form said surface being treated; at least one masking resistant to the electrochemical activation action of the decoration and interposed between the facing electrode and the surface being treated; and has the electrochemical action of activating the decoration of the treated surface occurs by electrochemical oxidation of the metallic oxide layer normally present on the electrically conductive surface whether it is placed below the PVD coating layer, i.e., performed before such PVD coating, or such electrochemical oxidation action is performed above said vacuum metallic coating, electrically conductive PVD layer; the electrochemical oxidation acts with the surface of the treated metal, its natural oxide, or the PVD coating itself, i.e., on the oxides, carbides, nitrides forming it, without any removal of metallic material but with the aesthetic modification of the treated surface in the shape determined by the aforesaid masking.
