AMPCO-TRODE 10

Description and Application

AMPCO-TRODE 10 aluminum bronze is the most versatile welding electrode in this family of alloys. It is intended for deposition with electric arc welding processes.

AMPCO-TRODE 10 will weld and join many ferrous and nonferrous metals and combinations of dissimilar metals. These metals include the more weldable grades of cast  iron, high and low carbon steels, copper, bronze and copper-nickel alloys. Applications for AMPCO-TRODE 10 include: building up bearing surfaces, joining and fabricating copper alloys, overlaying for resistance to corrosion and erosion and general maintenance and repair welding.
