Applications for High Grade 4N5 SHG Zinc Ingots
The exceptional purity of 4N5 zinc makes it essential for applications where standard commercial grades won’t suffice, and trace elements must be strictly controlled.
- Continuous galvanising lines require SHG zinc for consistent coating quality.
- High-end zinc alloy production (e.g., specific Zamak variants) demands ultra-pure source material.
- Chemical manufacturing uses high purity zinc anodes and powders.
- Electroplating applications rely on pure zinc for superior finishes and process control.
- Battery production requires high grade zinc ingots for dependable performance.
- Die Casting complex, durable parts for automotive, electronics, and appliance industries.
