Lead Metal Alloying Process

Gravita offer various Lead Alloys manufacturing processes & Kettle / Pots, which are of highest precession of desired Specification. Company’s strength lies in process to manufacture Lead-Calcium Alloy and Lead Selenium Alloy, which are used in grid casting for maintenance free & low maintenance Lead-Acid Battery manufacturing.

Company supply alloying pots of various capacities ranging from 5-35 MT per batch accompanied by high efficiency natural gas / LPG Gas / furnace oil burners equipped with preheating arrangements. The system is equipped with designed sets of Pollution Control equipments. Company configures the total alloying plant package(s) as required.

Gravita has the capability to manufacture different Lead alloys to stringent user-industry determined specifications:
