Description

2.0401 (CuZn39Pb3) 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. 2.0401 (CuZn39Pb3) 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. It shows the following features and properties:

Free machining

Good corrosion resistance

Good strength levels
