In the previous report, some characteristics of the six kinds of white bearing alloys have been studied, and in this paper, some properties of Pb-Ca-Na alloys and others were investigated. The results of this investigation were as follows : -(i) Beyond certain values of current density, the hardnesses of alloys once reached the maximum values and decreased to the constant values. And the time required to reach those maximum values varied with current densities. (ii) The ratio of NaCl/CaCl_2 was desired to be small. (iii) Addition of Sn at Zn to Pb-Ca-Na alloy did not effected on the hardnesses of alloys and Sn improved the fluidity and on the other hand, Zn made it worse. (iv) Although the properties for wear of Pb-Ca-Na alloys with no additions were very different from those of other alloys under heavy loads and dry-condition, alloys had similar relations under other conditions, and the properties of Pb-Ca-Na-Sn alloy resembled exceedingly to those of Sn-base white metal.
