Lead Alloys
Engineered for Performance
At Gee Emm Industries, we manufacture a wide range of lead alloys tailored to the specific needs of the battery and industrial sectors. Using spectrometer-controlled refining and alloying kettles, we ensure consistent chemistry, mechanical properties, and lot traceability.
Antimonial Lead (Pb-Sb)
-
Sb content: 1.8% to 2.5% (as per requirement)
-
Used in automotive, inverter, and industrial battery grids
-
Improves hardness, strength, and corrosion resistance
Selenium Lead (Pb-Se)
-
Small selenium additions for fine grain structure (over 0.025%)
-
Reduces grid growth, enhances conductivity, preferred in modern low-maintenance batteries
Calcium Lead (Pb-Ca-Sn)
-
Advanced alloys with 0.03–0.10% Ca and controlled Sn
-
Provides mechanical strength with low water loss
-
Suitable for sealed maintenance-free (SMF/VRLA) batteries
Tin Lead (Pb-Sn)
-
Improves corrosion resistance and durability
-
Used in specialty applications like radiation shielding, cable sheathing, and soldering alloys
Pure Lead (99.97%+)
-
Base metal
-
Used directly or as a foundation for alloying
