CZ121 offers the highest possible machinability of any copper alloy.
This alloy is a free-machining brass with a 3% lead content - the addition of lead is finely dispersed throughout the microstructure of the material which acts as both a lubricant and chip breaker; this results in giving the alloy its free machining characteristics. With a machinability rating of 100%, CZ121 is the standard by which all other copper-based alloys are rated. The alloy also offers good corrosion resistance and strength.
CZ121 offers good corrosion resistance and good strength. The alloy promotes excellent hot formability with the highest machinability of any copper alloy.
Commercial applications for this engineering material include:
