For manufacturers, material purity directly determines product performance — and our C1100 copper strip delivers uncompromising quality, with a copper + silver content of ≥99.9% and negligible impurities. Its electrical and thermal conductivity ranks among the top tier of industrial pure copper grades, making it a versatile choice for a wide range of high-precision applications.
This isn’t just a single-purpose material. In the electronics industry, it’s a staple for flexible PCBs and high-frequency connectors, cutting signal transmission loss by over 20%. In mold manufacturing, it serves as mirror EDM electrodes and hot runner heat sleeves, boosting heat dissipation efficiency and machining precision. Even in medical devices, it’s used in sensors and magnetocardiography components, ensuring accurate data collection and low-noise signal transmission.

FAQ
Q: Is the C1100 copper strip really 99.9% pure?
A: Absolutely! Our C1100 strictly adheres to the JIS H3100 standard, with Cu + Ag content guaranteed to be ≥99.9% and total impurities ≤0.1%. Each batch comes with a third-party inspection report, with clear, verifiable data — on-site verification is also welcome.
Q: Is C1100 copper strip suitable for high-temperature environments?
A: It performs well in general industrial temperature ranges, but avoid using it in reducing atmospheres above 370℃. Due to its trace oxygen content, it may experience "hydrogen embrittlement" in such environments, leading to cracking. Normal hot working (900-1050℃) and annealing (500-700℃) processes are fully compatible.
Q: What’s the difference between C1100 and other copper grades?
A: C1100’s core advantage is its high cost-performance ratio. Its purity is close to oxygen-free copper, with almost identical electrical and thermal conductivity, but at a more affordable price point. It also offers better machinability than T2 copper — bending and stamping without cracking. Compared to T2, C1100 has stricter impurity control, making it ideal for high-precision applications like high-frequency electronics and precision molds.
Q: Do you provide processing services after purchase?
A: Definitely! We offer cut-to-size, slitting, stamping, and bending services. The minimum slitting width is 5mm, with a cutting precision of ±0.05mm. No matter what shape or size you need, we can customize it to your requirements, saving you the trouble of secondary processing — parts are ready for immediate use upon delivery.
