A Guide to Brass CZ121 CNC Machined Parts: Properties, Applications and Design Considerations
What is CZ121?
CZ121 (CW614N) is an alpha/beta (duplex) brass alloy containing 37 to 39% zinc. These duplex alloys have restricted ductility being harder and have a higher tensile strength than alpha alloys which contain less than 37% zinc.
CZ121 typically contains 3% lead, giving great high speed, free machining characteristics (machinability rating of 90-100, the highest of any copper alloy).
As a result CZ121/CW614N is the European brass grade of choice for many machined components.
Main Attributes of Brass CZ121:
- Excellent machinability
- High tensile strength
- Good corrosion resistance
- Easily soldered or brazed
- Good conductivity
- Good spark resistance
- Toughness at all temperatures - excellent for hot working (between 630 - 730°C)
- Low magnetic permeability
