RepTec Cu8
CEWELD®E CuAl8 is an alkaline electrode for bonding aluminum bronzes with an Al content of max. 10 %, as well as for wear-resistant and corrosion-resistant coatings on steel, cast steel and cast iron, especially when exposed to erosion.
by erosion. CEWELD®E CuAl8 is suitable for filling cavities in new aluminum castings, as a buffer layer between Cu and Ni alloys and as a bearing material under high compressive stress.

by erosion. CEWELD®E CuAl8 is suitable for filling cavities in new aluminum castings, as a buffer layer between Cu and Ni alloys and as a bearing material under high compressive stress.
The weld metal of CEWELD®E CuAl8 offers good wear and corrosion resistance. The weld metal has good mechanical properties, is acid-resistant and resistant to seawater and erosion.
Welding instructions: - Preheating for sections >6 mm from 150 to 300 ºC is recommended. For thick sheets, a V-seam with a 90° opening angle should be made. Preferably weld in a horizontal position (PA) electrode perpendicular to the workpiece with a short arc, low current and high speed.
