Aluminum Bronze A4 electrode is a nickel-aluminum bronze alloy used to weld cast and wrought nickel-aluminum bronze. It has excellent resistance to corrosion, erosion, and cavitations in salt or brackish water. Aluminum Bronze A4 applications include, ship fittings, ship propellers, power plant valves, piping systems, intake screens, oil recovery pumps, and propeller gear housings .

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.

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.

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.
