ERNi-CI
UNS N02215
AWS A5.15
Corrosion-Resistant Alloy used for welding of cast irons to other cast irons as well as for joining cast irons to mild steels and stainless steels. Readily used for the repair of castings
Ni 99 (AWS class ERNi-CI) is a nominally 99% Nickel wire. Nickel is expensive, and so, therefore, is this premium wire. The wire will deposit welds that are machine-able, an important consideration when the casting is to be machined after welding. Repairs made with Ni 99 are often single pass welds with high admixture. Even with high admixture, the weld deposit will remain machine-able. It works best on castings with low or medium phosphorous contents.
