Lead Anode plates are primarily made from materials such as lead Ingot, Ingot Tin, and T2 Copper, each of which must meet specific industry standards. Lead Ingot should meet the GB/T469-2023 standard, ensuring a purity level of 99.9986%. Ingot Tin is required to comply with GB/T 728-2020, with a minimum purity of 99.90%. T2 Copper, which is used in the production of anode plates, must meet GB/T 1527-2017 equivalent to ASTM C11000， guaranteeing a purity of 99.99%. These standards ensure that the materials used for lead anode plates are reliable and perform well in industrial applications.
