Nickel Calcium

Nickel Calcium (NiCa) increases the resistance to stress fracture and corrosion

NiCa 6% is useful for final deoxidation, sulfide inclusion shape control, and desulfurization. Its addition improves the melt fluidity and enhances the machinability. These characteristics facilitate the hot working of cast steel ingots. NiCa also increases the resistance to stress fracture and corrosion.

It is mainly utilized for desulfurization and deoxidation of Ni-based alloys, stainless and heat resistant alloys, low alloyed steel and super alloy industry.

NiCa has a density of 7.3 to 7.6 g/cc which is greater than that of liquid cast iron. (The theoretical density is 7.6 g/cc.) This allows for a clean, consistent calcium addition to molten iron and steel under controlled conditions.

Calcium is not only a scavenger for deleterious elements but, when present as a residual, it can improve ambient and high temperature properties of both ferrous and nickel-base alloys.
