Weldability
CW614N has poor weldability. Because of its material properties, processes such as gas, TIG (WIG) or MIG welding are not suitable. If welding cannot be avoided in the process, resistance welding is the most appropriate option.
Detail
Machinability
CW614N is among the copper alloys with the best machinability. Machining yields smooth surfaces and generally favorable chip formation. The process typically produces short, needle-like chips. Specific machining parameters vary especially with the material’s strength condition.
Detail
Forgeability
CuZn39Pb3 is frequently used for forging applications. Thanks to its good formability, even complex forged parts can be reliably produced.
Detail
Magnetic behavior
The alloy exhibits diamagnetic characteristics as long as free iron is not present.
Detail
Corrosion resistance
Compared with other copper alloys, the corrosion resistance of CW614N is relatively poor. This is mainly due to the high zinc content, which makes the material more sensitive to water, saline solutions and organic fluids. Associated with this is dezincification, a form of corrosion that can occur in certain waters. The alloy is also susceptible to stress corrosion cracking, which can be reduced by appropriate heat treatments.
