LEAD ALLOYS
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:
