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
