DESCRIPTION

The alloy SF-CuAl8 has been developed for welding copper alloys and for coatings on steel, steel castings, nickel alloys and for fixing works in artistic foundries. Excellent for metal spraying. This material offers a very high resistance to seawater-corrosion and to the most commonly used acids in any concentration and at any temperature they may be needed. High erosion resistance. Often used for welding galvanized steel sheets.
