Pure Lead
Product Description
Sunraj Industries imports Pure Lead Ingots and exports Lead Sheets, Lead Pipes, wires, Sticks and Foils. Lead Sheets are widely used in the building industry for flashings or weathering to prevent water penetration & for roofing and cladding. The high density of Lead Sheet makes it a very effective material for sound insulation purpose.Lead pipes due to its corrosion resistant properties are used for carriage of corrosive chemicals at chemical plants.
Because of its high ductility, good extrusion ability, relatively low temperature & excellent proven corrosion resistance when in contact with a wide range of industrial and marine environments, soils and chemicals, Lead Alloys are used extensively as sheathing materials for high voltage power cables.

Radiator Alloy
Product Description
Sunraj Industries Imports , Exports and Distribute Radiator Alloys in Foils , wire , sticks and Ingots in various composition of 20/80 ( 20 percent Tin and 80 Percent Lead ), 30/70 ( 25 percent Tin and 75 Percent Lead ), 30/70 ( 30 percent Tin and 70 Percent Lead ), 35/65 ( 35 percent Tin and 65 Percent Lead ), 40/60 ( 40 percent Tin and 60 Percent Lead ).These are widely used in Radiator Tank Assembly, End Dipping and Tube Coating The Solder Joints of all these series are bright and shine without lumps, and joints have excellent heating radiation characteristic.
Titanium is a lightweight material whose density is approximately 60 percent of steel tubing and 50 percent of nickel and copper alloy tubing. Typical applications included marine, refinery, pulp and paper, chlorine and chlorate production, hydrometallurgy, and various other oxidizing and mildly reducing chemical services.
