Special-Shaped Lead Brick Heavy Industry Lead-Antimony Alloy Product Description An antimony-containing lead alloy used in the manufacture of grids and conductive parts for lead-acid batteries. Compared with pure lead, it has a lower melting point, good fluidity in molten state, easy casting and molding, and high hardness after solidification; the disadvantage is that the gas evolution overpotential of the grid is low. In order to reduce the precipitation of gas during charging of the battery, reduce self-discharge and improve corrosion resistance, the antimony content has been gradually reduced from the traditional 5% to 7% to about 2% or even lower. At the same time, a small amount of other components such as tin, arsenic, sulfur, selenium and copper are selectively added to improve the physical and chemical properties of the alloy. Welding temperature 287℃-294℃. According to the welding temperature, the composition ratio is also different. Physical: Lead (Pb99) : melting point 327℃, density 11.34g/cm3. Tin (Sn99.95) : melting point 232℃, density 7.29g/cm3. Antimony: melting point 630℃, density 6.62 g /cm3.
