Analysis and Control of Copper Brittleness Defects in Nickel Free Weather Resistant Box Boards
Copper containing weather resistant box boards are prone to copper brittleness defects during the nickel free production process.The morphology and causes of copper brittleness defects were analyzed by using OM(optical microscope)and SEM(scanning electron microscope),and improvement measures were proposed.By optimizing the composition and rolling process.The surface copper brittleness defect has been improved,achieving industrial and stable production of nickel free weather resistant box boards.
