Explore our top-tier copper alloy materials engineered for precision and performance
C11000, commonly known as Electrolytic Tough Pitch (ETP) copper or pure copper, is one of the most widely used copper grades in the world. With a copper purity of ≥99.90% and outstanding electrical conductivity reaching up to 101% IACS, it stands as the benchmark material for electrical and thermal applications across industries.
Its exceptional ductility, corrosion resistance, and ease of fabrication make C11000 the preferred choice for manufacturers in Hanoi and across Southeast Asia who demand reliability in high-stakes applications such as electrical wiring, heat exchangers, busbars, and precision connectors.
Power cables, busbars, motor windings, transformer components, and EV charging connectors all rely on C11000's unmatched conductivity.
Available in rods, strips, sheets, tubes, and wires — C11000 is easily machined, welded, and formed to meet complex engineering requirements.
C11000 is 100% recyclable without loss of properties, supporting Vietnam's green manufacturing goals and circular economy initiatives.
A decade of excellence in copper alloy innovation and manufacturing
Understanding the local industrial landscape and commercial demand for pure copper materials
Hanoi has emerged as one of Vietnam's most dynamic industrial hubs, with manufacturing output growing at over 8% annually. Industrial zones such as Thang Long, Noi Bai, and Quang Minh host hundreds of electronics, automotive, and precision engineering factories — all of which are major consumers of high-quality C11000 copper alloy materials.
Vietnam's commitment to electric vehicle adoption and 5G network rollout is driving unprecedented demand for C11000 pure copper. EV charging infrastructure alone is projected to require thousands of tonnes of high-conductivity copper by 2030, with Hanoi at the centre of this transformation.
Vietnam's booming lithium battery and energy storage sector — supplying both domestic and export markets — relies heavily on C11000 copper for current collectors, bus bars, and relay components. Hanoi-based battery manufacturers are scaling up procurement of premium copper alloys.
The concentration of electronics assembly plants and precision machining workshops in Hanoi's industrial zones creates strong local demand for C11000 rods and strips. These are used in connectors, terminals, heat sinks, and semiconductor packaging components.
While Vietnam produces some copper, the majority of high-purity C11000 alloy material is imported from China, South Korea, and Japan. Hanoi-based importers and distributors are actively seeking reliable long-term suppliers who can offer consistent quality, competitive pricing, and fast delivery cycles.
Hanoi's strategic location near the Chinese border and its well-connected logistics network make it an ideal re-export hub for processed copper components. Local factories are increasingly value-adding C11000 materials into finished parts for export to Japan, South Korea, and Europe.
Key technological and market forces shaping the future of pure copper alloy materials
Each electric vehicle requires 3–4× more copper than a conventional car. Vietnam's NEV market is expanding rapidly, with Hanoi leading EV adoption. C11000 is essential for motor windings, battery connectors, and charging systems — making it a critical strategic material for the automotive transition.
The rollout of 5G networks across Vietnam demands massive quantities of high-conductivity copper for antenna systems, signal transmission cables, and base station components. C11000's superior electrical performance makes it the material of choice for telecom infrastructure.
Vietnam's advanced manufacturing sector is rapidly adopting laser cutting and plasma cutting technologies. C11000 pure copper is used in laser nozzles and cutting heads due to its excellent thermal conductivity and resistance to high-temperature deformation.
Solar panel installations, wind turbine generators, and grid-scale energy storage systems all rely on C11000 copper for efficient power transmission. Vietnam's ambitious renewable energy targets are creating long-term structural demand for pure copper alloy materials.
As Hanoi's factories embrace Industry 4.0 automation, robotic systems and precision CNC equipment require high-quality copper components. C11000 rods and strips are machined into connectors, slip rings, and electrode tips for automated production lines.
Hanoi's rapid urbanisation is driving demand for copper in building wiring, plumbing, HVAC systems, and architectural applications. C11000's antimicrobial properties also make it increasingly popular in healthcare facility construction projects across the city.
