ASTM B280 C11000 Copper Flat Bar - 101.6x6.35x2540mm
Our high-quality ASTM B280 C11000 Copper Flat Bar is meticulously engineered for superior electrical conductivity and mechanical durability. Also known as electrolytic tough pitch (ETP) copper, this busbar is designed to meet the rigorous demands of industrial power distribution, grounding systems, and heavy-duty electrical applications.
With precise dimensions of 101.6 mm x 6.35 mm x 2540 mm (4 inches x 0.25 inches x 100 inches), this product offers an optimal balance of cross-sectional area and length for minimal resistance and efficient installation. Manufactured under strict ASTM standards, it guarantees consistent hardness, excellent corrosion resistance, and a conductivity rating of 100.98% IACS, ensuring maximum energy efficiency.
Whether you are building switchgear, panel boards, or renewable energy systems, this copper flat bar provides the reliability and performance required for critical infrastructure.

How It Works
Copper busbars operate on the principle of low-resistance power distribution. Unlike insulated cables, a flat copper bar provides a rigid, high-surface-area conductor that minimizes electrical resistance (Joule heating) and voltage drop.
Due to the high conductivity of C11000 copper (100.98% IACS), electrons flow efficiently through the solid metal structure. The flat rectangular shape (101.6mm x 6.35mm) optimizes the skin effect in AC applications, ensuring that the majority of the current travels across the wide surface area rather than the core. This results in superior thermal dissipation and allows for higher current-carrying capacity in a compact form factor compared to round cables of equivalent cross-section.

Frequently Asked Questions
Q1: What is the difference between C11000 and standard copper?
A: C11000 is Electrolytic Tough Pitch (ETP) copper, the most common type of high-conductivity copper. It contains a minimum of 99.9% copper and is the industry standard for electrical applications requiring conductivity above 100% IACS.
Q2: Can this copper bar be cut to custom lengths?
A: Yes. While the standard dimension listed is 2540 mm, we offer custom cutting services ranging from 0 to 6 meters (6000 mm) to meet your specific project requirements.
Q3: Is this bar suitable for outdoor use?
A: While copper has natural corrosion resistance, prolonged exposure to harsh outdoor environments may cause tarnishing. For outdoor applications, we recommend applying anti-oxidation coating or tin-plating to maintain optimal conductivity and aesthetics.
Q4: What is the minimum order quantity (MOQ)?
A: The MOQ is 200 kg. However, for samples or smaller trial orders, please contact our sales team to discuss feasibility.
Q5: How is the product packaged for shipping?
A: The bars are securely packaged in sturdy wooden boxes to prevent bending, scratching, or oxidation damage during transit.
