Virami Steel Hub is a leading manufacturer, supplier, stockist, and exporter of Copper Commercial Grade Round Bars in Mumbai, India. We supply these premium copper bars across India and export globally to the USA, Europe, Middle East, Canada, Australia, and Southeast Asia.
Copper commercial grade is known for its excellent electrical and thermal conductivity, corrosion resistance, and ductility, making it one of the most widely used non-ferrous metals in electrical, mechanical, and industrial applications. Copper round bars are used extensively in wiring, electrical components, plumbing, heat exchangers, and precision engineering parts.
Copper Commercial Grade Round Bars are solid cylindrical rods made from high-purity commercially pure copper (C11000 / ETP Copper). These bars combine excellent conductivity, corrosion resistance, and machinability, making them highly versatile in industrial, electrical, and mechanical applications.
Key features of copper commercial grade round bars:
These properties make copper round bars suitable for electrical bus bars, mechanical components, plumbing, heat exchangers, and precision engineering.
These features make commercial copper round bars essential for electrical, industrial, and mechanical engineering applications.
Copper commercial grade bars typically conform to C11000 / ETP (Electrolytic Tough Pitch) copper with the following composition:
| Element | Composition (%) |
|---|---|
| Copper (Cu) | 99.90% min |
| Oxygen (O) | 0.02 – 0.05% |
| Impurities (Fe, Pb, Zn) | 0.05% max |
Role of Purity
High-purity copper ensures reliable electrical performance and superior mechanical properties.
Copper commercial grade round bars provide excellent mechanical and physical properties:
These properties make copper bars suitable for structural, electrical, and thermal applications where ductility, formability, and conductivity are required.
