Copper bars and rods consist of ≥99.9% pure copper (electrolytic tough pitch or oxygen-free types). They have excellent thermal and electrical conductivity and are, therefore, suited for electrical applications. Mechanical characteristics usually consist of tensile strength between 210 and 250 MPa, elongation of 30–45%, and Brinell hardness of 40–60 HB. They possess high ductility and resistance to corrosion. General grades conform to ASTM B187/B187M. Depending on temper (half-hard, hard, annealed), copper bars can be hot or cold worked for diverse manufacturing purposes in stressful industrial applications.

Yes, Copper Bars and Rods can be susceptible to galvanic corrosion when in contact with dissimilar metals, particularly in the presence of moisture or electrolytes. Proper insulation helps prevent this.
Yes, Copper Bars and Rods are fully recyclable. The material retains its properties after recycling, making it an eco-friendly choice for sustainable industrial applications and reducing environmental impact.
Yes, Copper Bars and Rods can be used for natural gas applications. They offer excellent corrosion resistance and conductivity, making them suitable for gas systems, provided they are properly maintained.
Copper rods and bars are unavoidable in a broad array of industries. In the electrical industry, they are used as wiring conductors, terminals, motor components, switchgear parts, and busbars based on their better conductivity. Construction industries employ them for architectural accents, grounding systems, roofing, and plumbing. Due to their outstanding resistance to biofouling and corrosion, they are the preferred choice for marine and HVAC use. They also appear in power substations, transformers, and generators. They are turned into custom fittings, bolts, and fasteners in the manufacturing industry. Copper‘s antimicrobial nature allows them to fit equally well in food processing and healthcare environments as well.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
