Using X-ray diffractometry, double bridge method and dynamic resonance technique structure, electrical resistivity, elastic modulus, internal friction and thermal diffusivity of Pb63-xSn30Sb7Cux [x=0 or x≤2.5] quaternary melt spun alloys have been investigated. Adding Cu to PbSn30Sb7 decreases electrical resistivity, elastic modulus and internal friction. The PbSn30Sb7Cu1 melt spun alloy has better properties as bearing alloy, such as low electrical resistivity, high elastic modulus and adequate internal friction, compared with the Pb88Sn10Cu2 alloy used for automotive applications (FIAT Normalizzazione). That means, it has good properties as lead free (non-toxic) bearing alloy.
