Copper grades are considered to be commercial metals of their excellent thermal and electrical conductivity and other featured strength and properties.
These grades are non-magnetic and are joined by brazing and soldering. Some of the copper grades are welded by different arc, gas, and resistance methods.
Copper grades have six family divisions: brasses, copper-nickel alloys, dilute copper alloy, bronzes, and nickel-silver alloys. Each family may differ when it comes to physical attributes including texture and appearance, chemical composition, and mechanical properties.
Please see the table below to view distinctions between the following copper grades.
|C613||has good formability and machinability||valve and pump components, marine equipment, pole line hardware, high strength fasteners|
|C623||has excellent corrosion resistance; has good acid resistance||used in industrial process streams|
|C624||has excellent corrosion resistance; heat treatable to high strength||marine equipment, pole line hardware, high strength fasteners|
|C30||corrosion resistant; has typical tensile strength||pump and valve components for industrial process streams|
|C632||corrosion resistant; has moderate strengt||marine equipment, high strength fasteners, valve and pump components, pole line hardware|
|C70600||corrosion resistant in marine environments; has good creep resistance and moderate high strength at elevated temperatures||used for seawater service, fittings and hardware, valve and pump components|
|C70690||copper-nickel alloys||marine applications|
|C70610||copper-nickel alloys||marine applications|
|C71500||has moderate high strength; corrosion resistant in marine environments; creep resistant at elevated temperatures||machined and forged pump and valve components, hardware and fittings|
