Zinc Oxide | Lead Alloys | Pondy Oxides & Chemicals

Pondy Oxides & Chemicals is a leading secondary lead smelter in India producing the highest quality lead, lead alloys, master alloys, tin alloys, babbit alloys and zinc oxide. They are India’s first and only London Metal Exchange registered Secondary Lead brand.

The highest quality lead and lead alloys and PVC additives are supplied to customers who are mainly battery manufacturers, chemical manufacturers and manufacturers of PVC extruded and moulded products. About Fifty percent (50%) of the production is exported to numerous international customers mainly but not limited to the Asian region like South Korea, Japan, Indonesia and Middle East.

LEAD

Lead has been one of the oldest metal known to have widespread uses commonly due of its properties like easy extraction and to work with, highly malleable, corrosion resistant and so on. The largest known pre industrial producer of lead was the Roman economy, which accounted for about 40% of world production back then. The main uses were construction and ornamentation. Even today Lead continues to be used in the modern society extensively and is an ever-growing industry.

Uses of Lead:

The largest use of lead is in the lead acid battery industry. It is also used for radiation shielding, ammunitions, roofing sheets, extruded products, solders in the electronic, plumbing and automotive industry. Some other uses like cable sheathing, pigments, glass and others also contribute to the consumption of lead.
