Why E-Ni99 ?

1) pure nickel core

2) strong reducing power

3) graphite type electrode

4) welding: no preheating, good crack resistance and machinability 5) suitable for AC and DC

6) relatively expensive

7) used for thin welding cast iron parts and maintenance of welded surfaces such as cylinder heads, engine bases, gearboxes and lathe rails cast iron parts

 E-Ni99 Application field：

Suitable for connection of non-ferrous and ferrous metals, heavy castings requiring machinability, repair of broken castings, engine covers, pump housings, ingot molds
