C11000 PCB Copper Foil

Material introduction:C11000(Cu ETP)

Cu ETP is an electrolytically refined oxygen-containing copper. It has good electrical conductivity but compared with other high conductivity copper due to the high residua oxygen content of the alloy it is not suitable for processing (annealing welding etc.) and use in high temperature ( temperature greater than 370 ° C ) reducing gas. Because it is prone to hydrogen embrittlement when the material is heated to 600 ° C or higher the oxygen inside the material will form water vapor with the hydrogen in the air causing the internal structure of the material to be brittle and cremated so hydrogen embrittlement occurs.

Material Features:

1. Cu copper content is greater than 99.9% oxygen content 5-40 PPM
2. Compared with oxygen-free copper C10200 OFC the processing cost is lower.
3. Not suitable for use at temperatures above 370 ° C prone to hydrogen embrittlement
4. Widely used in electronic parts of electrical components, electrical products

Founded in 1998 as Keram Equipment Co., LTD, KERAMCONTROLS launched as a specialized manufacturer of pressure control products—laying the groundwork for its growth as a trusted player in the industrial components space. By 2005, the firm had expanded its portfolio to three distinct product lines, surpassing $100,000 in annual sales: a milestone that highlighted its growing market relevance and ability to adapt to the evolving needs of industrial clients.

A defining expansion followed in 2006, when the company moved operations to Huai’an Industrial Park (Jiangsu Province) and added a dedicated production line for heating system equipment—broadening its capabilities to serve a wider range of industrial and commercial heating requirements.

In 2009, KERAMCONTROLS entered a strategic joint venture with a leading German enterprise: aligning its manufacturing processes with rigorous German quality standards, expanding its heating equipment offerings, and cementing its reputation for technical excellence and reliability.

In 2014, the company re-branded as KERAMCONTROLS CO., LTD and relocated its headquarters to Nanjing—a move to enhance regional market access, streamline operations, and position itself for broader domestic and international growth. Building on this momentum, 2020 saw significant investments in sensor /transmitter product technologies: reinforcing its commitment to advancing performance, energy efficiency, and sustainability to meet the demands of modern industrial and commercial stakeholders.

In 2025, KERAMCONTROLS will establish a dedicated research and development center, focusing on the innovative research and development of sensor-related products.

Rooted in its core values—Customer First, Quality-Oriented, Keep Innovating, Dedication, and Faithful—

With a global design concept, KERAMCONTROLS is committed to becoming a high-quality supplier in the industry, providing industry-leading and highly reliable solutions, fostering long-term strategic partnerships, and adhering to the highest operational integrity standards within its global business scope.
