What are C12000 Cu Bars?
The C12000 Copper Bar is also known as Phosphorus Deoxidized Copper. This bar is at least 99.9% copper and a tiny bit of Iron and Manganese is added for strength. This copper bar is strong and can handle pressure. It's also a good conductor of electricity and useful for electrical applications. It is easy to bend, weld, and solder naturally resistant to rust, and conducts heat well. These bars are used in pipes, heat exchangers, and building parts.

C12000 copper bar consists of copper with a purity of over 99%, characterized by a Cu-ETP (Electrolytic Toughness Pitch) grade with traces of silver and oxygen. The copper content is typically around 99.9%, making this alloy highly resistant to corrosion and oxidation in acidic and alkaline environments. Its ductility, malleability and thermal conductivity make it suitable for a variety of industrial applications. In addition, its excellent electrical conductivity makes it the material of choice for all electrical components such as heat sinks, switch parts, junction boxes and more.
FAQ
Q: What is the main advantage of C12000 over standard C11000?
A: The main advantage is weldability. C11000 (ETP) contains oxygen and can suffer from "hydrogen embrittlement" (cracking) when welded or brazed in a hydrogen atmosphere. C12000 is deoxidized, making it safe for gas welding, brazing, and torch soldering.
Q: Can C12000 be used for electrical applications?
A: Yes. While its conductivity (85-98% IACS) is slightly lower than pure C11000 (100% IACS), it is still considered an excellent conductor. It is widely used for welded electrical assemblies, switchgear components, and connectors where fabrication requires joining.
Q: What sizes do you offer in C12000 bars?
A: We offer a comprehensive range:
Round Bars: 3mm to 300mm diameter
Square Bars: 5mm to 150mm
Flat Bars: Thickness from 3mm to 50mm, Width from 20mm to 300mm
Lengths: Up to 4 meters standard, with custom lengths available
Q: Does the bar come with a Mill Test Certificate (MTC)?
A: Yes. All our C12000 Copper Bars are shipped with traceable Mill Test Certificates certifying the chemical composition and mechanical properties as required by ASTM B187 standards.
C12000 Electrolytic Copper Bar Packaging and Transportation
To ensure your C12000 Copper Bars arrive in pristine condition, we employ a rigorous multi-layer packaging process. Each bar is carefully cleaned and dried to prevent surface oxidation, then securely bundled with heavy-duty steel straps to prevent shifting during transit. The bundles are wrapped in a protective layer of moisture-resistant kraft paper followed by a polyethylene film barrier, safeguarding against humidity and mechanical damage. For international shipments, all materials are packed in seaworthy plywood cases or reinforced pallets, fully compliant with export standards, guaranteeing that your order arrives at your facility factory-fresh and ready for fabrication.
