Brass Half Round Bar CZ121 is a semi-circle shaped CZ121 Brass Alloy bar. CZ121 Brass Alloy is a free-machining brass consisting of a duplex phase structure with a 3% lead content. It is suited to high speed machining operations due its superior machinability, thread rolling and knurling characteristics. Particles of lead are finely dispersed throughout the microstructure, acting as both a lubricant and a chip breaker to give the alloy its free-machining characteristics. CZ121 Brass Alloy’s machinability rating of 100 is the standard against which all copper alloys are rated. It offers good strength, is easily soldered or brazed and has good resistance to corrosion.
