Sažetak

The paper presents results of the studies into microstructure and mechanical properties of PbCa grade alloys for starting battery grids. Three lead-calcium alloys with alloy additions of aluminium, tin, silver and magnesium were studied. Lead alloys were produced in laboratory tests from industrial master alloys and pure elements. The examined alloys have monophase microstructure of tin solid solution in the lead. The range between liquidus and solidus temperatures is c.a. 10 °C. The mechanical properties alloys depend on the amount of tin. PbCa alloys exposed to the process of natural ageing increase their strength, proof strength and hardness, simultaneously the plasticity decreases.
