Selecting a premium copper rod is crucial for ensuring peak performance in demanding electrical, thermal, and mechanical applications worldwide. Hangzhou Target Import & Export Co., Ltd. is a specialized B2B non-ferrous metal supplier. We export high-grade round bar solutions sourced from top-tier Chinese processing factories. We offer an extensive inventory of high-conductivity alloys. This includes C10100 (Oxygen-Free Electronic), C11000 (Electrolytic Tough Pitch), and C14500 (Tellurium Copper), designed to meet rigorous international standards.
Our global logistics network and expert technical consultation ensure that industrial clients receive the precise materials required for their operations. Whether your business operates in power distribution, advanced electronics manufacturing, or precision CNC machining, we supply high-purity materials optimized for your specific fabrication challenges. By coordinating sourcing, custom processing, and worldwide shipping under one roof, we streamline your supply chain. This allows us to deliver reliable, long-term non-ferrous metal solutions.
Our copper round rods are manufactured and supplied in strict accordance with prominent global standards, including ASTM B187 and relevant UNS designations. By working with top-tier private and state-owned Chinese mills, we guarantee consistent metallurgical properties. Our material provides tight dimensional tolerances and reliable mechanical characteristics across all batches.
Below is a technical overview of our primary copper alloys. It details their chemical purity, conductivity benchmarks, and available tempers to assist procurement managers in selecting the ideal material:
| Alloy Grade (UNS) | Common Name | Minimum Purity (%) | Electrical Conductivity (% IACS) | Standard Temper Options | Primary Features |
|---|---|---|---|---|---|
| C10100 | Oxygen-Free Electronic (OFE) | 99.99% | 101% | Soft Annealed (O60), Half-Hard (H02), Hard (H04) | High vacuum compatibility, zero hydrogen embrittlement, ultimate purity |
| C11000 | Electrolytic Tough Pitch (ETP) | 99.90% | 100% | Soft Annealed (O60), Half-Hard (H02), Hard (H04) | Outstanding electrical and thermal conductivity, excellent formability |
| C14500 | Tellurium Copper | 99.50% (Nominal) | 90% - 98% | Half-Hard (H02), Hard (H04) | Superior machinability (85% rating), high thermal and electrical conductivity |
Alloy 101 represents the pinnacle of purity in our product line. It features a minimum of 99.99% pure copper with virtually zero volatile impurities. This exceptional purity yields a guaranteed minimum electrical and thermal conductivity of 101% IACS. Because it is manufactured in an oxygen-free environment, C10100 is immune to hydrogen embrittlement. This makes it the absolute standard for high-vacuum electronic devices, semiconductor fabrication, and critical medical instrumentation where outgassing must be avoided entirely.
As the primary industry workhorse for electrical applications, Alloy 110 contains a minimum of 99.90% copper. It exhibits excellent electrical conductivity of at least 100% IACS. This variant is highly favored for its exceptional cold and hot workability, ductility, and resistance to atmospheric corrosion. These characteristics make ETP materials the optimal choice for electrical switchgears, busbars, power transmission components, and heavy-duty grounding systems.
When high-volume CNC machining is required, pure copper can be difficult to cut efficiently due to its ductility. Alloy 145 addresses this challenge by incorporating a precise addition of tellurium. This modification yields a machinability rating of 85% while retaining up to 98% of the electrical and thermal conductivity. Tellurium copper rods significantly reduce tooling wear and produce short, manageable chips. This makes them ideal for manufacturing electrical connectors, fasteners, and welding torch tips.
At Hangzhou Target, we understand that standard mill lengths do not always align with your direct operational needs. To minimize scrap rates, reduce preparation labor, and shorten assembly times, we offer comprehensive custom processing services. Our precision cut-to-length services utilize advanced industrial bandsaws to deliver custom metric or imperial dimensions. We maintain tight dimensional tolerances tailored directly to your manufacturing blueprints.
Additionally, we provide customized surface treatments. These include polishing, oiling, and customized protective coatings to safeguard materials against atmospheric oxidation during long-distance maritime transit. Our advanced capabilities also extend to custom diameter drawing, chamfering, and specialized profile shaping. This ensures your materials arrive fully prepared for immediate installation.
Due to their exceptional physical properties, our round copper bars serve as critical components across diverse heavy industries. They are essential in energy infrastructures and specialized high-tech applications. Our technical consultation team works closely with engineering partners to select the optimal alloy and temper for each operational environment.
High-conductivity ETP and oxygen-free copper bars are widely utilized in heavy-duty power infrastructure. Applications include high-voltage busbars, distribution panelboards, switchgear terminals, transformer windings, and grounding systems where energy loss must remain minimal.
In the manufacturing and automotive sectors, tellurium variants are highly favored for producing high-speed machined connectors. They are perfect for electrical contacts, fasteners, plumbing nozzles, and welding torch tips. Their excellent chip-breaking characteristics suit automated Swiss-screw machining perfectly.
Ultra-pure, oxygen-free materials are indispensable for specialized vacuum seal interfaces, electron tubes, and semiconductor fabrication equipment. They also support high-frequency transmitters and medical diagnostic machinery. The absence of oxygen ensures high resistance to embrittlement and exceptional reliability in ultra-high vacuum environments.
