Lead Alloy

Lead alloys are used in a range of applications including:

Solder:

lead solder is used extensively by the electronics industry

Terne plate:

iron and steel can be protected against corrosion by coating the surface with a lead based alloy.

Brass and Bronze Products:

lead had traditionally been used in bearings and bushings to reduce wear and friction in certain type of machinery.

We use Pyrometallurgical process to produce specific Lead Alloys at our Alloying Plant. We have kettle pots of various capacities ranging from 12-35 tonnes per batch accompanied by high efficiency furnace oil burners equipped with preheating arrangements. Emissions control is achieved by a flexible kettle hood venting into a venturi scrubber attached to an induction draft fan along with a chimney/stack arrangement.

It is a matter of pride for us to state that our plant has the capacity to manufacture divergent Lead alloys as per stringent user-industry determined specifications:
