Storage Method: To maintain the effectiveness of zinc and pure copper plates, it is recommended to wrap them in fiber film and store in a dry place; This storage method can prevent oxidation of the material and ensure that its protective performance is maintained when it is for use. 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 galvanizing copper and zinc; These materials ensure useful and the reliability of the project. Package Content: You will receive 6 pieces of pure zinc plate and 6 pieces of pure copper plate; The sufficient quantity provided ensures that enough materials for various projects without worrying about the shortage of material. Ideal Size: The appropriate size for each copper zinc cathode is about 0.04 inch x 0.98 inch x 5.98 inch / 1 mm x 25 mm x 152 mm; 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 research scientific. Widely Used Compared with other metals, metal zinc has high efficiency and electroplating is very easy. It is widely used to protect steel parts, especially to prevent oxidation and corrosion in the air; Copper electroplating is widely used as pre-coating in electroplating industry; They are suitable for industrial applications such as machinery and marine engineering, ships and port facilities., Weight: 0.80027801106 Pounds, Manufacturer: Rtxbvg
