KEI has specially developed Tin (Sn) bearing Copper for manufacture of Copper Radiator Fins for higher tensile strength and resistance to annealing. Tin bearing Copper is being manufactured in thickness up to 0.04 mm and slit width from 20mm to 350mm.
Tensile Strength is more than ETP Copper. Hardness is equivalent to ETP Copper. Good electrical conductivity of 80% IACS. Resistance to Annealing - Heat Proof Maximum Coil Weight is 8Kg/mm width.
Copper Radiators Fins for Automobile as well as Industrial application, Heat Ex-changers, Terminal for Automotive Batteries, Connector Pins, Fuse Boxes in Automobile.
