9V Laminated Battery
When manufacturing 9V laminated battery, zinc foil is usually used as one of the negative electrode materials, zinc foil provides stable support and conductive path for the electrode structure inside the battery, and its excellent conductivity improves the energy output efficiency of the battery to ensure that the battery can provide power statically. In addition, the corrosion resistance of zinc helps to extend the life of the battery, preventing corrosion or degradation during storage and use.
Hardware and Electrical Products
In the hardware and electrical industry, zinc foil is used to produce various components, such as grounding devices, switches, electrical shielding materials, etc. Its superior electrical conductivity and corrosion resistance ensure reliable performance in critical electrical applications, help prevent electromagnetic interference and improve safety.
Building and Decorative Materials
Zinc foil's durability and corrosion resistance are widely used in roofing and wall cladding in the construction industry, as well as in interior decoration. In addition, the ease of processing of zinc foil allows for the creation of complex decorative patterns, further increasing its value in building materials.
1. Usually, how heavy is a coil?
The multiple of each coil is related to the width, the larger the width, the heavier, more than ten kg to 500kg.
2. Under normal circumstances, what is the diameter of the inside diameter?
The inner diameter is conventional 200-250mm, the outer diameter is about 500mm, and the inner diameter of 300mm with the inner core can also be done, but it will be wider and the thickness is within 1mm.
