GB/T ECu
AWS A5.6 ECu
Description: T107 is a pure copper electrode with pure copper as the core and covered with low-hydrogen sodium type flux. Use DCEP (direct current electrode positive). Good mechanical properties, good corrosion resistance to atmosphere and sea water, not suitable for welding oxygen-containing copper and electrolytic copper. Application: It is mainly used for welding copper components such as conductive copper bars, copper heat exchangers, and seawater conduits for ships. It can also be used for surfacing welding of carbon steel parts resistant to seawater corrosion. Chemical composition of weld metal(%):| Cu | Si | Mn | P | Pb | Fe+Al+Ni+Zn |
