Hindalco's lampcap stock is used in GLS lamps and tube lights
Hindalco's lampcap stock combines strength and high formability with high resistance to softening in vitriting. Manufactured at modern and well-equipped mills, it can be rolled to very fine tolerances, allowing more caps per tonne of coil and enabling uninterrupted operations of high-speed forming presses.
