Z408 cast iron electrode 
 Model GB / T: EZNiFe-1 is equivalent to AWS: ENiFe-CI 
 Description: welding nickel-iron alloy core, strong strong reduction of the iron rod of graphite, high strength, good plasticity, low coefficient of linear expansion. Crack resistance of gray cast iron and the Z308 is almost, but the cast iron than in Z30 
 8 strong, high phosphorus (0.2% P) of the cast iron also has a good effect. Cutting of somewhat less than the Z308 and Z508 for the room temperature or slightly preheated (to about 200 ℃) gray iron and ductile iron welding, AC and DC arc stability, and good technology. 
 Uses: used in important high-strength gray cast iron and ductile iron welding, such as cylinder, engine, seat and other gear. 
 Chemical Composition of Deposited Metal /% 
 C ≤ 2 Si ≤ 2.5 Mn ≤ 1.8 Fe I Ni 45-60 

 Z408A cast iron electrode 
 Model GB / T: EZNiFe-Cu 
 Description: welding nickel-copper alloy of iron core, strong reduction of the iron strong graphite electrode, AC, DC, can be all-position welding, high strength, good plasticity, and base metal fusion and good characteristics, similar to cutting of the Z408 , arc stability, welding is not red, technology is good, the equivalent of the Swiss Forest Company 2240 Custer electrode. 
 Uses: used in important high-strength gray cast iron and ductile iron welding, such as cylinder, engine, seat and other gear. 
 Chemical Composition of Deposited Metal /% 
 C ≤ 2 Si ≤ 2. Mn ≤ 1.5 Fe I Ni 45-60 Cu 4-10
