Etp Copper Wire Rod for Cable

The twist test is a reliable indicator of rod quality. We take samples regularly and twist them until they break. The break pattern tells us about internal structure. A clean, ductile break indicates good material. A brittle, jagged break indicates problems. Our workers have learned to read these signs accurately. They also monitor the rod surface for scale or pits. Surface defects cause breaks during drawing. We reject any material that shows issues. We also track breakage rates from customer feedback. This data helps us refine our process. Our goal is continuous improvement in drawing performance. We also monitor the oxide layer thickness. Too much oxide affects drawing. Too little oxide may indicate other issues.
