Description
1. Product Overview
Refined Zinc Ingots are high-purity (99.995% min) non-ferrous metal slabs produced via electrolytic refining. They are primarily used for hot-dip galvanizing of steel, die-casting alloys, and brass production. The key value proposition is superior corrosion resistance, consistent melt performance, and low impurity-driven waste. As a critical material in construction, automotive, and infrastructure, securing reliable zinc ingot supply directly impacts downstream production uptime and finished product longevity.

3. Core Industrial Applications
-
Hot-dip galvanizing (steel construction, automotive frames, transmission towers): Lower dross formation (≤3% waste reduction vs. standard grade) cuts rework and zinc consumption by 5–7%.
-
Die-casting alloys (auto parts, hardware, electronics housings): High fluidity and exact composition enable thinner walls (0.5 mm) and 40% faster cycle times.
-
Brass & bronze production (valves, fittings, musical instruments): Ultra-low lead/cadmium meets RoHS and EU drinking water directives without downstream refining.
-
Chemical applications (zinc oxide, sulfate): Consistent purity yields predictable reaction rates, reducing batch rejection by 12–15%.
