Researches on brass containing Pb as the material used for precision mechanism (clock and watch, etc.) have been performed, concerning the machinability for cutting and shearing, the qualities of worked surface, and the wear properties. In the first report the experimental results of the mechanical properties, that is hardness, tensile strength, elongation and shock value are described.
