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.

Applications

Binary Nickel-Iron (Ni-Fe) and Ni based complex welding alloys are supplied in welding rod and wires in standard length or length up to the consumers' request. For normal service conditions, the chemical compositions are available in various Ni contents according to the most of American and European standards.

Our customers can buy ERNi-CI online according to their requests.
