3.15mmX350mm Nickel Aluminum Bronze Welding Rod

Alloy Description And ApplicationNickel-Aluminum Bronze filler metal is used for MIG and TIG welding of cast and wrought nickel-aluminum bronze parts such as ship propellers, where high resistance to corrosion, erosion and cavitations in salt or brackish water is required. Nickel-Aluminum Bronze is a very popular filler metal in offshore technology for such items as sea-water desalting, shipbuilding and repair. Also used in the power plant and chemical industry for pumps and tube systems. Helium may be preferred when TIG welding on Al-bronzes that has 300°F maximum inter pass recommendations.Typical Gmaw Welding Procedures; DCEP Spray transferWire Diameter Wire Speed (ipm) Amps Volts Argon (cfh)0.023 460-580 60-120 21-22 20-250.030 450-525 130-160 21-24 20-300.035 385-455 155-190 23-25 25-300.045 275-310 210-235 26-28 30-351/16 150-240 250-310 27-31 35-40Typical Welding Procedures; DCEN with EWTh-2 truncated conical tipFiller Wire Size Tungsten Amps Volts Gas Cup Size Argon (cfh) Base thickness1/16" 1/16" 80-170 12 3/8-1/2" 20 1/16-1/8"3/32" 3/32" 140-275 12 3/8-1/2" 20 1/8- 3/16"1/8" 1/8" 200-375 12 1/2" 25 1/4-3/8"1/8-5/32" 3/16" 260-475 12 1/2-3/4" 30 3/8-1/2"Procedures may vary with change in position, base metals, filler metals, equipment and other changes.Copper base may need preheat and high side of range, Bronze base may need preheat and mid-high side of range, Steels preheat per carbon contentCHEMICAL COMPOSITION REQUIRMENT (%) AND PHYICAL PROPERTIES;Zinc 0.02 Solidus 1904° FIron 3.0-5.0 Liquidus 1940°FSilicon 0.10 Density (lbs/in3) 0.275Aluminum 8.5-9.5 Thermal Conductivity 37.0 BtuLead 0.02 Brinell Hardness 160-200Copper Remainder Elongation 23 %Manganese 0.60-3.50 Tensile Strength (psi) 72-140,000Nickel 4.0-5.5 Yield Strength (psi) 35-60,000All single values on composition are maximum percentages & Total others elements 0.50AVAILABLE SIZES: TCU CU-NI-AL = Spools of .035, .045, 1/16TCU CU-NI-AL/ Cut lengths of .045, 1/16, 3/32, 1/8, 5/32Other sizes available – please inquireSPECIFICATIONS; ANSI/AWS A5.7 ERCuNiAlASME SFA 5.7 ERCuNiAl
