GENERAL CHARACTERISTICS
High-alloyed bronze electrode contains aluminum, nickel, and manganese. The unique formula with flux coating makes this electrode outstanding for a wide range of applications.
TYPICAL APPLICATIONS: Structural joining, repair and surfacing of high manganese steel, nickel and iron-containing aluminum bronzes, steel, tin bronzes (phosphor bronze), brass and copper. Also for cast iron surfacing. Commonly used on ship propellers, turbines, valves, thrust bearings, stirrer blades, guides, suction rolls and parts of hydraulic equipment. Construction of machines, fittings, instruments and pumps for the chemical and paper industries. Dissimilar metals are also joined with this electrode.

Procedure:
Preheat copper base metals to 570o F; do not heat other materials. Maintain a short arc. Apply thin layers using either stringer beads or weave beads. Remove slag between passes. Allow part to cool slowly. In most applications it will not be necessary to machine the surface after welding.
