E CuMn SMAW Stick Electrodes




E CuMn

 
TYPE 
Copper based electrode developed for joining and cladding.
APPLICATIONS 
E CuMn is suitable for welding and overlaying copper and copper alloys, Cast Iron and steel.
PROPERTIES 

Ductile welding deposit with high conductivity and corrosion resistance. The weld deposit is free from porosity and offers similar strength as most commercial copper grades. Thicker sections than 5 mm should be preheated upto approximately 500°C.
