Key Features
Zinc Coil at up to 99.99% purity is zinc foil in a continuous spooled format, bringing the metal's moderate electrical conductivity, hexagonal close-packed structure, and well-documented electrochemical behavior to roll-to-roll processing and automated converting operations:
Moderate Electrical Conductivity (5.96 µΩ·cm Resistivity) for Battery & Coating Applications
An electrical resistivity of 5.96 µΩ·cm gives Zinc Coil the moderate electrical conductivity needed for continuous production of battery electrode stock and electroplating feedstock, where zinc's well-documented electrochemical behavior supports reliable performance in established anode and coating chemistries.
Naturally Forming Oxide Layer for Good Corrosion Resistance
Zinc's naturally forming oxide layer provides good corrosion resistance, supporting Zinc Coil's use in continuous production of galvanized coatings and sacrificial anode strips — though surface oxidation under ambient conditions should be accounted for in applications relying on long-term conductive performance.
Low Melting Point (419.5 °C) & Moderate Mohs Hardness (2.5) for Easy Processing
A melting point of 419.5 °C and moderate Mohs hardness of 2.5 allow easy slitting and forming of Zinc Coil, supporting straightforward integration into automated electroplating lines and high-volume anode fabrication without specialist processing equipment.
Continuous Coil Format for Automated Electroplating & Anode Fabrication
The coil format provides the uninterrupted length needed for automated electroplating lines and high-volume anode fabrication, ensuring consistent strip geometry and surface condition across the full roll length for continuous galvanization and battery anode strip production.
Reproducible Strip for Electrochemical Testing & Coating Studies
In research and pilot production, Zinc Coil supports reproducible electrochemical testing and corrosion coating studies across consistent strip lengths — providing a well-characterized zinc substrate for systematic investigation of anode performance and coating system behavior.
Industrial Applications
Zinc Coil is used across battery manufacturing, electroplating and galvanization, corrosion protection, and electrochemical research wherever a continuously processed, moderately conductive zinc strip is required:
- ✦ Zinc-Battery Anode Strip Production
- Used in zinc-battery anode strip production, where zinc's well-established role as an anode material in primary and secondary battery chemistries, combined with the coil format's consistent geometry, supports high-volume continuous fabrication of battery anode stock for alkaline, zinc-carbon, and emerging zinc battery systems.
- ✦ Electroplating & Galvanization Feedstock
- Applied as electroplating and galvanization feedstock, where the coil format provides the uninterrupted length required for automated electroplating lines, and zinc's good corrosion resistance through its naturally forming oxide layer ensures reliable, consistent galvanized coating performance across continuous production runs.
- ✦ Corrosion-Protection Coating Manufacture
- Used in corrosion-protection coating manufacture, where zinc's sacrificial anode behavior and naturally forming protective oxide layer provide established corrosion protection performance for coated steel and other substrates in atmospheric and industrial service environments.
- ✦ Sacrificial Anode Strip Production
- Used in sacrificial anode strip production, where zinc's well-documented electrochemical behavior and the coil format's processing consistency support continuous manufacture of cathodic protection anode strips for marine, infrastructure, and industrial corrosion protection applications.
- ✦ Electrochemical Testing & Corrosion Coating Research
- Used in research and pilot production to support reproducible electrochemical testing and corrosion coating studies, where the coil format provides consistent strip lengths for systematic investigation of zinc anode performance, Coulombic efficiency, and coating system durability under controlled experimental conditions.
