OXYGEN-FREE COPPER ANODE

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

CHEMICAL STRUCTURE AND DESCRIPTION:

Oxygen-Free (OF) Copper Anode is a high-purity (≥ 99.99%) copper material with extremely low oxygen content (< 0.001%). It has a face-centered cubic (FCC) crystal structure. It offers higher electrical conductivity and better mechanical properties compared to standard electrolytic copper. The absence of oxygen reduces gas evolution in vacuum applications and eliminates the risk of hydrogen embrittlement at high temperatures. It is widely used as an anode in electrolytic plating processes, in electrical and electronic applications requiring high conductivity, in vacuum devices and high-frequency systems, in cathodic protection systems, and in metal refining and electrochemical production.

Structural Features:

• Face-centered cubic (FCC) crystal structure

• Very high electrical conductivity

• Low oxygen content (< 0.001%)

• High purity (≥ 99.99%)

• Excellent ductility

• Good mechanical properties

12. SUMMARY AND CRITICAL WARNINGS

SUMMARY:

Oxygen-Free Copper Anode is a high-purity (≥ 99.99%) copper anode material with very low oxygen content (< 0.001%). It has a density of 8.96 g/cm³, melting point of 1,085 °C, and electrical conductivity of ≥ 101% IACS.

Its most important applications include use as an anode in electrolytic plating processes, in high-conductivity electrical and electronic applications, in vacuum devices and high-frequency systems, in cathodic protection systems, and in metal refining and electrochemical production.

Non-toxic in solid form, but copper dust may be harmful if inhaled. Storage should be in dry, clean, moisture-free environments.

Key Properties:

CRITICAL WARNINGS:

1. High Purity: Oxygen-Free copper has ≥ 99.99% purity. Lower oxygen content compared to standard copper reduces gas evolution in vacuum applications and eliminates hydrogen embrittlement risk.

2. Oxygen Sensitivity: The absence of oxygen eliminates the risk of hydrogen reaction at high temperatures (no hydrogen embrittlement).

3. Surface Cleanliness: Dirt, oil, and oxide layers on the surface reduce electrical performance. Surface cleaning before use is important.

4. Dust Inhalation: Copper dust inhalation may cause respiratory tract irritation. Prolonged exposure may cause metal fume fever risk.

5. Customs Tariff Code: 7407.10.00

6. Recycling: Copper is highly recyclable. At the end of service life, it should be sent to recycling facilities.
