CZ121 Machining, Properties & Components
What is CZ121?
CZ121 is an alpha/beta brass alloy that contains 3% lead for improved machinability (machinability rating of 90-100, the highest of any copper alloy). The lead remains insoluble in the microstructure of the brass and the soft particles act as chip breakers.
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
- Low magnetic permeability
