Cost-Effective Choice with Good Performance
Our ETP copper rod offers a balanced solution for many customers. It has slightly higher oxygen content than oxygen-free material. But it costs less to produce. The price difference is significant. Many cable manufacturers choose ETP when they do not need maximum conductivity. The performance remains good for most applications. Our team monitors the oxide layer during production. A thick oxide layer affects downstream drawing. We control the oxide thickness through cooling water adjustment. This method came from years of experience. Our workers have refined the process over many runs. The result is a consistent product at a competitive price.
Oxide Layer Control
The oxide layer on ETP rod must stay within a specific range. Too much oxide and the wire breaks during drawing. Too little oxide and the rod surface may suffer. Our cooling system applies water at the right flow rate. This controls oxidation effectively. We test samples regularly to verify the oxide thickness. The visual appearance also tells us a lot. A uniform color indicates consistent oxidation. Our workers check every coil. We also monitor the copper temperature. Temperature affects oxidation rates. Our process keeps temperature within a narrow band. This helps maintain consistency.
