Material introduction:C11000(Cu ETP) Cu ETP is  an  electrolytically refined  oxygen-containing copper. It has good electrical conductivity butcompared 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  material will form water vapor with the hydrogen in the air causing the internal structureof 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 Physical properties
