COPPER

1400 is an all position Phos-Bronze electrode used for joining copper base alloys to themselves and to stainless steels and cast irons. It is excellent for overlays on pumps, shafts, impellers and propeller blades. 1400 is used for building up bearing journals and frictional wear surfaces on heavier sections, galvanized iron, and ornamental iron. It provides a good color match on bronze and will work harden. Weld deposits are ductile, strong, and machinable. 1400 offers corrosion resistance to salt water and chemicals.

Aluminum Bronze A1 is an iron free alloy used primarily to overlay bearings and wear-resistant surfaces that require a 125 BHN hardness and to resist corrosion, especially from salt water, metal salts and acids in varying concentrations and temperatures. It is not recommended for joining since the deposit has a tendency to be hot short. Applications include, tube sheets, valve seats, pickling hooks, impellers, chemical plants, and pulp mills.

Aluminum Bronze A2 is a very versatile bare wire. It is used for joining aluminum bronze of similar composition, silicon and manganese bronze, high strength copper-zinc alloys, some copper-nickel alloys, ferrous metals and dissimilar metals. Dissimilar applications include aluminum bronze to steel and copper to steel. It is also used for building up or overlaying metal for wear and corrosion resistant surfaces. Aluminum Bronze A2 is most commonly used for marine maintenance and repair welding of ship propellers, pump housings, rigging jacks, piston heads, bearings and many overlay or surfacing applications.

Deoxidized Copper provides dense, high quality deposits with relatively high electrical conductivity for use in joining and overlay with inert gas processes. It is used to fabricate deoxidized copper, repair weld copper castings, to weld galvanized steel and deoxidized copper to mild steel where high strength joints are not required. Applications include, billet molds, conductor rolls, heater elements, bus bars, copper connectors, and steel mill electrode holders.

Low Fuming Bronze is available in bare and flux coated rods. It is a machinable brazing alloy used on steels, copper alloys, nickel alloys, and stainless steel. Low Fuming Bronze has a high tensile strength and good ductility. The weld deposits are non-porous for leak proof joints for water, oil and gas lines. The weld deposit freezes rapidly from fluid to a plastic state. Brazing flux is recommended.

Nickel Silver is a low fuming, cadmium free bronze that is available in bare or flux coated rod. It is an excellent replacement for high cost silver brazing alloys when higher brazing temperatures are acceptable. Weld deposits have very high tensile strength, good ductility and excellent corrosion resistance. The weld deposits are also machinable and work-harden when put into service. Brazing flux is recommended.

Phos-Bronze C is recommended for high strength welds on phosphor bronze materials. Weld deposits have high tensile and yield strengths and greater hardness due to the 7 to 9 percent Tin content. It is used as an overlay on cast iron or steel, to join dissimilar metals, for maintenance repair and fabrication of valve bodies, seats, bearings, bushings, gears, propellers, impeller blades and housings. Preheat is recommended.

Silicon Bronze contains 3% Silicon and trace amounts of manganese, tin and zinc. It is used for oxy-acetylene welding and GMAW welding of copper, copper-silicon and copper-zinc metals to themselves and to steel. Silicon Bronze is excellent for plain or galvanized steel sheet metal as well as other coated steels. It is also used for surfacing areas that are subjected to corrosion. For oxy-acetylene welding, the gas flame should be slightly oxidizing. Keep the weld puddle small in order to promote fast solidification and minimize cracking. Preheat is NOT recommended.
