What is Copper Bars and Rods

Our Copper Bars and Rods are typically made from 99.9% pure copper, delivering exceptional thermal and electrical conductivity (up to 101% IACS for ETP copper). Depending on the temper and processing, these products boast tensile strengths ranging from 200–400 MPa. They are incredibly ductile, resistant to corrosion, and easy to machine, braze, or weld. OFHC copper, in particular, offers enhanced conductivity and is free from oxygen, making it perfect for high-vacuum or hydrogen applications. You can find our copper rods and bars in round, square, and rectangular profiles, making them suitable for a variety of forming and joining techniques in industrial settings.

Copper Bars & Rods Uses

Copper Bars and Rods are extensively used in electrical busbars, switchgear, grounding systems, motor components, and conductors thanks to their excellent conductivity. In the construction sector, they find applications in roofing, flashing, and plumbing fittings. For marine and industrial uses, they are ideal for heat exchangers, fasteners, and corrosion-resistant fittings. Plus, copper’s antimicrobial properties make it a great choice for medical and food-grade equipment. With its recyclability, strength, and resistance to weathering, copper is an environmentally friendly and durable option for components that face mechanical stress and diverse environmental conditions.
