Tin Plated Copper


General Specifications:

We manufacture a wide range of Tin plated (Hot Dip) Copper conductors. Tin plating protects the copper from the corrosion and also allows high temperature insulation processing compare to bare (plain) copper wire. We manufacture this range in compliance with the specification IS 8130, ASTM B 174-90, BS 6360 for wires and cables as per IS 694, IS 1554, IS 9968, IS 7098.

Our range covers 0.00785 to 240sqmm with individual strand diameters 0.1mm to 1.29 mm.
