Aufhauser Phosphor Bronze A Electrode is useful for welding copper tin bronzes (Cu-Sn 6-8%) and some brasses (Cu-Zn). Also suitable for joining wrought copper-tin bronzes and brasses to cast iron and carbon steel. The PhosBronze A Electrode is recommended for repairing wrought bronzes (Cu-Sn); for surfacing on brasses, steels, and cast iron. The deposit is resistant to salt water corrosion. This electrode is especially designed to weld with the alternative current, but it can be used either on DC positive or negative. PhosBronze A Electrodes may be used to weld copper if the resultant weld metal has adequate electrical conductivity and corrosion resistance for the specific application. Postweld heat treatment is desirable for maximum ductility, especially if the weld metal is cold worked.

APPLICATIONS

• Joining base metals of similar composition
• Construction of equipment for the chemical industry and petrochemical industry
• Naval constructions and installations for sea water desalination, repair works

GENERAL INFORMATION

Note: Copper contains Silver. All values are maximum percentage, unless shown in range. * Total Other elements include Manganese, Nickel, Silicon, Zinc.

ADDITIONAL INFORMATION

Copper and its alloys require a relatively high heat input with shortened welding time. Higher preheat temperatures and faster welding rates than for steel are necessary.
