LEAD ALLOYS

Gravita Alloying plant is capable to produce all kind of Lead Alloys as per the customer requirement Like: Antimony Lead Alloy, Calcium Lead Alloy, Selenium Lead Alloy, Copper Lead Alloy, Lead Tin Alloys, Arsenic Lead Alloy etc. Emissions control is achieved by a flexible kettle hood venting into a Venturi scrubber attached to an induced draft fan along with a chimney/stack arrangement.

Our plants have the capability to manufacture different Lead Alloys as per stringent user-industry determined specifications:
