Highest Conductivity for Premium Applications
Our OFHC copper wire rod has the best conductivity among our wire rod products. The conductivity reaches ≥97.3% IACS. This means very low energy loss during power transmission. The oxygen content is extremely low. This makes it suitable for the most demanding applications. Our customers in the premium cable sector specify this material. The high purity also improves surface quality. The rod draws smoothly into fine wire. There are fewer breaks and defects. Our team applies very tight process controls when producing this rod. Temperature fluctuations affect conductivity. So we monitor temperature carefully throughout production.
Strict Temperature Control
Cooling speed also affects the final properties. We control the cooling rate precisely. Every production run has complete records. This traceability helps us maintain consistent quality. We can trace any batch back to its production date. This helps with quality investigations if needed. Our workers check the rod surface regularly. They also sample for conductivity testing. The results must meet our internal standards. We keep records of all test results. This documentation supports our quality claims. The rod comes in 16mm and 20mm diameters.
