To any welders left here,
My neighbor moved and I ended up with about 15 lbs of 70/30 CuNi .045"
MIG wire. Besides welding copper/nickel alloys what else is it good
for? I can TIG weld with it but I don't know if it's good for anything
special, like welding cast iron.
Carlson alloy 70 30 Cu Ni is a copper nickel alloy with excellent
resistance to corrosion and erosion. It is strong and ductile. 70 30
Cu Ni is utilized in areas where high temperatures and pressures,
combined with high velocities and turbulence are serious problems. It
70 30 Cu Ni exhibits outstanding resistance to general and impingent
attack by clean sea water. It is, however, subject to bio-fouling at
low velocities. 70 30 Cu Ni also has excellent resistance to attack by
fresh water, boiler feedwater, and steam. It withstands the attack of
phosphoric, sulfuric, and mild organic acids. It is attacked by
chromic, hydrobromic, hydrochloric, and nitric acids. 70 30 Cu Ni is
resistant to alkaline chlorides, chromates, nitrates and sulfates. It
is, however, attacked by the cyanides and acid dichromates. 70 30 Cu
Ni resists wet and dry chlorine, bromine, and carbon dioxide at
70 30 Cu Ni is widely used in marine service, tidewater power plants,
desalinization plants, oil refineries, and in the chemical process
industry. It is utilized extensively as a condenser and salt water
tube and piping material for the U.S. Navy.
Product applications include condenser, heat exchanger and distiller
tubes, tube sheets and baffles, sale water piping, water boxes, tanks,
vats, pressure vessels, process equipment, pumps and valves.
Save some for yourself, but sell the rest on ebay, it is worth good
This is extremely corrosion resistant wire and you can use it for all
kinds of outdoor projects.
I have some monel mig wire also.
