Our aluminium strip for lamp base materials combines strength and high form-ability with high resistance to softening in vitriting. 3004 aluminum strip temper O is usually used for lamp base materials. 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.
