Applications
-
Electrical Industry: Used for busbars, electrical connectors, switchgear components, and transformer windings due to excellent conductivity.
-
Construction & Architecture: Ideal for roofing, flashing, facades, and decorative elements for their durability, weather resistance, and iconic appearance.
-
Industrial Machinery: Fabricated into heat exchangers, gaskets, and chemical processing vessels where thermal conductivity and corrosion resistance are critical.
-
Power Generation: Essential in renewable energy systems, including solar power collectors and grounding plates.
-
Manufacturing & Fabrication: Served as raw material for custom parts, prototypes, and OEM components that require high formability and reliability.
Working Principle
Pure copper functions by leveraging its atomic structure, which allows for the nearly unimpeded flow of electrons (electrical conductivity) and efficient transfer of kinetic energy from atoms (thermal conductivity). In practical terms:
-
As a Conductor: When integrated into an electrical circuit, the copper sheet provides a low-resistance path, minimizing energy loss as heat and ensuring efficient power distribution.
-
As a Heat Exchanger: In thermal applications, the copper plate rapidly absorbs heat from a source and dissipates it across its surface or to a cooling medium, making it ideal for managing temperatures.
-
As a Durable Material: Its inherent malleability and ductility (high elongation) allow it to be shaped and formed without cracking, while its corrosion resistance ensures long-term structural integrity in harsh environments.

Frequently Asked Questions
Q1: What is the difference between C11000 and C1100 copper?
A: C11000 is the ASTM (American) standard designation for Electrolytic Tough Pitch copper, while C1100 is the JIS (Japanese) standard for the same material. Both have a purity of 99.90% Cu min and are essentially equivalent in performance and composition.
Q2: Can you provide custom-cut sizes?
A: Absolutely. We specialize in customization. We can precision-cut sheets to your required length, width, and shape using our cutting, punching, and decoiling services. Standard sheets like 4x8ft are also available.
Q3: What is the meaning of "1/2 Hard" or "Hard" temper?
A: Temper indicates the cold-worked state of the copper. "Soft" or "Annealed" is highly malleable, "1/4 Hard" and "1/2 Hard" offer a balance of strength and formability, and "Hard" provides the highest strength but less formability. We can supply all tempers to suit your fabrication needs.
Q4: What are your packaging and delivery terms?
A: We use standard seaworthy packaging to ensure our products arrive damage-free. We offer flexible trade terms including FOB, CIF, CFR, and Ex-Work to facilitate smooth international logistics.
Q5: Why is the copper purity of 99.95% significant?
A: A higher purity level (99.95% vs. the common 99.90%) directly translates to even better electrical and thermal conductivity. This is a critical advantage for high-efficiency electrical systems and advanced thermal management applications, reducing energy loss.
