Round Copper Bar

CuMetal manufactures high-quality round copper bars (also known as copper rod) from premium C11000 electrolytic copper. Our round copper bars offer uniform dimensions, excellent surface quality, and superior electrical conductivity.

Product Overview

Round copper bars are widely used in electrical grounding systems, component manufacturing, and various industrial applications where a circular cross-section is required.

Key Features

Precision Diameter Control

Our round copper bars are manufactured with strict diameter tolerances, ensuring consistent sizing for your machining and assembly processes.

Multiple Temper Options

Available in both hard drawn (for structural strength) and soft annealed (for maximum conductivity and formability) tempers to suit your application.

Surface Quality

Bright, clean surface free from defects, with oxide-free options available for critical applications.
