CU9738 High-Purity Copper Ingot (6N)

High-Purity Copper Ingot (6N) Description

High-Purity Copper Ingot (6N) is manufactured from refined copper with a purity level of 99.9999%. The ingot is produced using controlled melting and casting methods that reduce oxygen content and trace metallic impurities. This ensures enhanced electrical conductivity and material homogeneity, supporting thermal management applications and precision processing. The standardized ingot shape facilitates further reduction processes and mechanical working while minimising contamination risks.

Electronics
- Used as a conductive element in printed circuit board heat sinks to address thermal dissipation issues by leveraging its low impurity levels.
- Applied as interconnects in high-current circuits to reduce resistive losses through its verified six-nines purity.

Industrial
- Used as a raw material in transformer windings to achieve improved current transfer by utilising its high conductivity.
- Applied in high-performance welding electrodes to ensure stable arc performance by taking advantage of its homogeneous structure.

Manufacturing
- Used as feedstock for precision copper foils in semiconductor packaging to minimise contamination by leveraging its controlled purity.

High-Purity Copper Ingot (6N) Packing

The ingots are packaged in moisture-resistant, inert gas-filled containers with an anti-static lining to prevent oxidation and particulate contamination. Each ingot is wrapped in clean-room sealed foil and securely placed in cushioned carriers for transit. The packaging design facilitates controlled storage under low-humidity and stable temperature conditions. Custom packaging options, including size-specific inserts and tamper-evident seals, are available to meet precise handling requirements.

Frequently Asked Questions
