C11000 PCB Copper Foil
GB/T | DIN | EN | ASTM |
TU2 | E Cu58 | Cu ETP | C11000 |
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
