C11000 CU ETP Strips

Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of c11000 cu etp strips in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount c11000 cu etp strips for sale here from our factory. Customized orders are welcome.

C10100, also known as Oxygen-Free Electronic (OFE) Copper, represents the pinnacle of copper purity. With a minimum copper content of 99.99% and an oxygen content controlled to less than 5 ppm (0.0005%), C10100 is engineered for industries where even the slightest impurity can lead to catastrophic failure.

Unlike standard ETP (Electrolytic Tough Pitch) copper, C10100 is produced by melting and casting copper in a high-vacuum or inert gas environment. This process eliminates oxides and volatile impurities, resulting in a material with exceptional electrical conductivity, thermal stability, and vacuum integrity.

Extreme High Conductivity: Achieving 101% IACS, it ensures minimal energy loss in high-precision circuits.

Superior Vacuum Integrity: Extremely low hydrogen embrittlement risk and low volatility in high vacuum, ideal for aerospace and vacuum tubes.

Excellent Formability: Outstanding ductility for deep drawing, bending, and complex stamping without cracking.

Perfect Weldability: Excellent for brazing and welding due to the absence of oxides at the grain boundaries.

To ensure the highest performance, our C10100 copper strips strictly adhere to international standards such as ASTM B152, ASTM B170 (Grade 1), and DIN EN 13601.

Thickness Range: From ultra-thin foils (0.01mm) to heavy-duty strips (3.0mm).

Temper Control: Available in Annealed (O), 1/4 Hard, 1/2 Hard, Full Hard, and Extra Hard to match your stamping requirements.

Surface Treatment: Options for Electro-tin plating, Silver plating, or Anti-oxidation (passivation) coating to extend shelf life.

Edge Finishing: Slit edge, Deburred edge, or Rounded edge for safety and precision fit.

Quality is the soul of our C10100 products. Every shipment is accompanied by a Material Test Report (MTR) including:

Chemical Analysis: Verified via Optical Emission Spectrometry (OES).

Conductivity Test: Verified via Eddy Current testing.

Mechanical Test: Tensile strength, Yield strength, and Elongation % verified.

Dimensional Inspection: Digital micrometers and laser gauges.

Compliance: Fully compliant with RoHS, REACH, and Conflict Minerals regulations.

Q: Is C10100 the same as Oxygen-Free Copper?
A: Yes, but specifically it is "Oxygen-Free Electronic" grade. While C10200 is also oxygen-free, C10100 has a higher purity (99.99%) and lower levels of specific impurities like phosphorus and sulfur.

Q: How do you prevent oxidation of the copper strip during storage?
A: We apply a microscopic anti-oxidation film (passivation) upon request and use multi-layer protective packaging. We recommend storing the material in a temperature-controlled, low-humidity environment.

Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, our MOQ starts at 100kg. For custom thicknesses or widths, it may range from 300kg to 500kg depending on the production cycle.
