99 Pb 6 Sn Lead Antimony Alloy For Medical And Dental Fields

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.
