Packaging content: You receive 6 pieces of pure zinc plate and 6 pieces of pure copper plate; The sufficient quantity provided ensures that you have enough materials for projects without worrying about material shortages. Reliable material: The pure copper electrode strip is made of 99.9% pure copper, which has a metallic luster and good conductivity and thermal conductivity; The pure zinc electrode strip is made of 99.9% pure zinc and is suitable for electroplating copper and zinc; These materials the service life and reliability of the project. Ideal size: The appropriate size for each copper zinc cathode is approximately 0.04 inches x 0.98 inches x 5.98 inches/1 millimeter x 25 millimeters x 152 millimeters; This convenient size is suitable for many applications; They are easy to operate and install, and can be used for school science experiments, school projects, laboratory applications, experiments, and scientific research. Storage method: To maintain the effectiveness of pure zinc and copper plates, it is recommended to wrap them in fiber film and store them in a dry place; This storage method can prevent material oxidation and that its protective performance is maintained when ready for use. Widely used: Compared with other metals, zinc metal has high efficiency and electroplating is very easy. It is widely used to protect steel parts, especially to prevent oxidation and in the air; Copper electroplating is widely used as a pre coating in the electroplating industry; They are suitable for industrial applications such as marine machinery and engineering, ships, and port facilities.
